MediaPlayer class can be used to control playback of audio/video files and streams.
MediaPlayer is not thread-safe. Creation of and all access to player instances should be on the same thread. If registering callbacks, the thread must have a Looper.

State Diagram
Playback control of audio/video files and streams is managed as a state machine. The following diagram shows the life cycle and the states of a MediaPlayer object driven by the supported playback control operations. The ovals represent the states a MediaPlayer object may reside in. The arcs represent the playback control operations that drive the object state transition. There are two types of arcs. The arcs with a single arrow head represent synchronous method calls, while those with a double arrow head represent asynchronous method calls.

From this state diagram, one can see that a MediaPlayer object has the following states:
- When a MediaPlayer object is just created using
newor afterreset()is called, it is in the Idle state; and afterrelease()is called, it is in the End state. Between these two states is the life cycle of the MediaPlayer object.- There is a subtle but important difference between a newly constructed
MediaPlayer object and the MediaPlayer object after
reset()is called. It is a programming error to invoke methods such asgetCurrentPosition(),getDuration(),getVideoHeight(),getVideoWidth(),setAudioAttributes(android.media.AudioAttributes),setLooping(boolean),setVolume(float, float),pause(),start(),stop(),seekTo(long, int),prepare()orprepareAsync()in the Idle state for both cases. If any of these methods is called right after a MediaPlayer object is constructed, the user supplied callback method OnErrorListener.onError() won't be called by the internal player engine and the object state remains unchanged; but if these methods are called right afterreset(), the user supplied callback method OnErrorListener.onError() will be invoked by the internal player engine and the object will be transfered to the Error state. - You must keep a reference to a MediaPlayer instance to prevent it from being garbage
collected. If a MediaPlayer instance is garbage collected,
release()will be called, causing any ongoing playback to stop. - You must call
release()once you have finished using an instance to release acquired resources, such as memory and codecs. Once you have calledrelease(), you must no longer interact with the released instance. - MediaPlayer objects created using
newis in the Idle state, while those created with one of the overloaded convenientcreatemethods are NOT in the Idle state. In fact, the objects are in the Prepared state if the creation usingcreatemethod is successful.
- There is a subtle but important difference between a newly constructed
MediaPlayer object and the MediaPlayer object after
- In general, some playback control operation may fail due to various
reasons, such as unsupported audio/video format, poorly interleaved
audio/video, resolution too high, streaming timeout, and the like.
Thus, error reporting and recovery is an important concern under
these circumstances. Sometimes, due to programming errors, invoking a playback
control operation in an invalid state may also occur. Under all these
error conditions, the internal player engine invokes a user supplied
OnErrorListener.onError() method if an OnErrorListener has been
registered beforehand via
setOnErrorListener(android.media.MediaPlayer.OnErrorListener).- It is important to note that once an error occurs, the MediaPlayer object enters the Error state (except as noted above), even if an error listener has not been registered by the application.
- In order to reuse a MediaPlayer object that is in the
Error state and recover from the error,
reset()can be called to restore the object to its Idle state. - It is good programming practice to have your application register a OnErrorListener to look out for error notifications from the internal player engine.
- IllegalStateException is
thrown to prevent programming errors such as calling
prepare(),prepareAsync(), or one of the overloadedsetDataSourcemethods in an invalid state.
- Calling
setDataSource(java.io.FileDescriptor), orsetDataSource(java.lang.String), orsetDataSource(android.content.Context, android.net.Uri), orsetDataSource(java.io.FileDescriptor, long, long), orsetDataSource(android.media.MediaDataSource)transfers a MediaPlayer object in the Idle state to the Initialized state.- An IllegalStateException is thrown if setDataSource() is called in any other state.
- It is good programming
practice to always look out for
IllegalArgumentExceptionandIOExceptionthat may be thrown from the overloadedsetDataSourcemethods.
- A MediaPlayer object must first enter the Prepared state
before playback can be started.
- There are two ways (synchronous vs.
asynchronous) that the Prepared state can be reached:
either a call to
prepare()(synchronous) which transfers the object to the Prepared state once the method call returns, or a call toprepareAsync()(asynchronous) which first transfers the object to the Preparing state after the call returns (which occurs almost right away) while the internal player engine continues working on the rest of preparation work until the preparation work completes. When the preparation completes or whenprepare()call returns, the internal player engine then calls a user supplied callback method, onPrepared() of the OnPreparedListener interface, if an OnPreparedListener is registered beforehand viasetOnPreparedListener(android.media.MediaPlayer.OnPreparedListener). - It is important to note that the Preparing state is a transient state, and the behavior of calling any method with side effect while a MediaPlayer object is in the Preparing state is undefined.
- An IllegalStateException is
thrown if
prepare()orprepareAsync()is called in any other state. - While in the Prepared state, properties such as audio/sound volume, screenOnWhilePlaying, looping can be adjusted by invoking the corresponding set methods.
- There are two ways (synchronous vs.
asynchronous) that the Prepared state can be reached:
either a call to
- To start the playback,
start()must be called. Afterstart()returns successfully, the MediaPlayer object is in the Started state.isPlaying()can be called to test whether the MediaPlayer object is in the Started state.- While in the Started state, the internal player engine calls
a user supplied OnBufferingUpdateListener.onBufferingUpdate() callback
method if a OnBufferingUpdateListener has been registered beforehand
via
setOnBufferingUpdateListener(android.media.MediaPlayer.OnBufferingUpdateListener). This callback allows applications to keep track of the buffering status while streaming audio/video. - Calling
start()has no effect on a MediaPlayer object that is already in the Started state.
- While in the Started state, the internal player engine calls
a user supplied OnBufferingUpdateListener.onBufferingUpdate() callback
method if a OnBufferingUpdateListener has been registered beforehand
via
- Playback can be paused and stopped, and the current playback position
can be adjusted. Playback can be paused via
pause(). When the call topause()returns, the MediaPlayer object enters the Paused state. Note that the transition from the Started state to the Paused state and vice versa happens asynchronously in the player engine. It may take some time before the state is updated in calls toisPlaying(), and it can be a number of seconds in the case of streamed content.- Calling
start()to resume playback for a paused MediaPlayer object, and the resumed playback position is the same as where it was paused. When the call tostart()returns, the paused MediaPlayer object goes back to the Started state. - Calling
pause()has no effect on a MediaPlayer object that is already in the Paused state.
- Calling
- Calling
stop()stops playback and causes a MediaPlayer in the Started, Paused, Prepared or PlaybackCompleted state to enter the Stopped state.- Once in the Stopped state, playback cannot be started
until
prepare()orprepareAsync()are called to set the MediaPlayer object to the Prepared state again. - Calling
stop()has no effect on a MediaPlayer object that is already in the Stopped state.
- Once in the Stopped state, playback cannot be started
until
- The playback position can be adjusted with a call to
seekTo(long, int).- Although the asynchronuous
seekTo(long, int)call returns right away, the actual seek operation may take a while to finish, especially for audio/video being streamed. When the actual seek operation completes, the internal player engine calls a user supplied OnSeekComplete.onSeekComplete() if an OnSeekCompleteListener has been registered beforehand viasetOnSeekCompleteListener(android.media.MediaPlayer.OnSeekCompleteListener). - Please
note that
seekTo(long, int)can also be called in the other states, such as Prepared, Paused and PlaybackCompleted state. WhenseekTo(long, int)is called in those states, one video frame will be displayed if the stream has video and the requested position is valid. - Furthermore, the actual current playback position
can be retrieved with a call to
getCurrentPosition(), which is helpful for applications such as a Music player that need to keep track of the playback progress.
- Although the asynchronuous
- When the playback reaches the end of stream, the playback completes.
- If the looping mode was being set to true with
setLooping(boolean), the MediaPlayer object shall remain in the Started state. - If the looping mode was set to false
, the player engine calls a user supplied callback method,
OnCompletion.onCompletion(), if a OnCompletionListener is registered
beforehand via
setOnCompletionListener(android.media.MediaPlayer.OnCompletionListener). The invoke of the callback signals that the object is now in the PlaybackCompleted state. - While in the PlaybackCompleted
state, calling
start()can restart the playback from the beginning of the audio/video source.

Permissions
One may need to declare a corresponding WAKE_LOCK permission
<uses-permission>element.This class requires the
Manifest.permission.INTERNETpermission when used with network-based content.Callbacks
Applications may want to register for informational and error events in order to be informed of some internal state update and possible runtime errors during playback or streaming. Registration for these events is done by properly setting the appropriate listeners (via calls to
setOnPreparedListener,setOnVideoSizeChangedListener,setOnSeekCompleteListener,setOnCompletionListener,setOnBufferingUpdateListener,setOnInfoListener,setOnErrorListener, etc). In order to receive the respective callback associated with these listeners, applications are required to create MediaPlayer objects on a thread with its own Looper running (main UI thread by default has a Looper running).Summary

Added in API level 26public void prepareDrm (UUID uuid)
Prepares the DRM for the current source
If
OnDrmConfigHelperis registered, it will be called during preparation to allow configuration of the DRM properties before opening the DRM session. Note that the callback is called synchronously in the thread that calledprepareDrm. It should be used only for a series ofgetDrmPropertyStringandsetDrmPropertyStringcalls and refrain from any lengthy operation.If the device has not been provisioned before, this call also provisions the device which involves accessing the provisioning server and can take a variable time to complete depending on the network connectivity. If
OnDrmPreparedListeneris registered, prepareDrm() runs in non-blocking mode by launching the provisioning in the background and returning. The listener will be called when provisioning and preparation has finished. If aOnDrmPreparedListeneris not registered, prepareDrm() waits till provisioning and preparation has finished, i.e., runs in blocking mode.If
OnDrmPreparedListeneris registered, it is called to indicate the DRM session being ready. The application should not make any assumption about its call sequence (e.g., before or after prepareDrm returns), or the thread context that will execute the listener (unless the listener is registered with a handler thread).Parameters uuidUUID: The UUID of the crypto scheme.

Added in API level 26public void seekTo (long msec, int mode)Moves the media to specified time position by considering the given mode.
When seekTo is finished, the user will be notified via OnSeekComplete supplied by the user. There is at most one active seekTo processed at any time. If there is a to-be-completed seekTo, new seekTo requests will be queued in such a way that only the last request is kept. When current seekTo is completed, the queued request will be processed if that request is different from just-finished seekTo operation, i.e., the requested position or mode is different.
Parameters mseclong: the offset in milliseconds from the start to seek to. When seeking to the given time position, there is no guarantee that the data source has a frame located at the position.

Added in API level 16public void selectTrack (int index)
Selects a track.
If a MediaPlayer is in invalid state, it throws an IllegalStateException exception. If a MediaPlayer is in Started state, the selected track is presented immediately. If a MediaPlayer is not in Started state, it just marks the track to be played.
In any valid state, if it is called multiple times on the same type of track (ie. Video, Audio, Timed Text), the most recent one will be chosen.
The first audio and video tracks are selected by default if available, even though this method is not called. However, no timed text track will be selected until this function is called.
Currently, only timed text, subtitle or audio tracks can be selected via this method. In addition, the support for selecting an audio track at runtime is pretty limited in that an audio track can only be selected in the Prepared state.
Parameters indexint: the index of the track to be selected. The valid range of the index is 0..total number of track - 1. The total number of tracks as well as the type of each individual track can be found by callinggetTrackInfo()method.Throws IllegalStateExceptionif called in an invalid state. See also:
setAudioAttributes
Added in API level 21public void setAudioAttributes (AudioAttributes attributes)
Sets the audio attributes for this MediaPlayer. See
AudioAttributesfor how to build and configure an instance of this class. You must call this method beforeprepare()orprepareAsync()in order for the audio attributes to become effective thereafter.Parameters attributesAudioAttributes: a non-null set of audio attributesThrows IllegalArgumentExceptionsetAudioSessionId
Added in API level 9public void setAudioSessionId (int sessionId)
Sets the audio session ID.
Parameters sessionIdint: the audio session ID. The audio session ID is a system wide unique identifier for the audio stream played by this MediaPlayer instance. The primary use of the audio session ID is to associate audio effects to a particular instance of MediaPlayer: if an audio session ID is provided when creating an audio effect, this effect will be applied only to the audio content of media players within the same audio session and not to the output mix. When created, a MediaPlayer instance automatically generates its own audio session ID. However, it is possible to force this player to be part of an already existing audio session by calling this method. This method must be called before one of the overloadedsetDataSourcemethods. Note that session id set using this method will override device-specific audio session id, if theMediaPlayerwas instantiated using device-specificContext- seeMediaPlayer.MediaPlayer(Context).Throws IllegalStateExceptionif it is called in an invalid state IllegalArgumentExceptionsetAudioStreamType
public void setAudioStreamType (int streamtype)
This method was deprecated in API level 26.
usesetAudioAttributes(android.media.AudioAttributes)Sets the audio stream type for this MediaPlayer. See
AudioManagerfor a list of stream types. Must call this method before prepare() or prepareAsync() in order for the target stream type to become effective thereafter.Parameters streamtypeint: the audio stream typeSee also:
setAuxEffectSendLevel
Added in API level 9public void setAuxEffectSendLevel (float level)
Sets the send level of the player to the attached auxiliary effect. See
attachAuxEffect(int). The level value range is 0 to 1.0.By default the send level is 0, so even if an effect is attached to the player this method must be called for the effect to be applied.
Note that the passed level value is a raw scalar. UI controls should be scaled logarithmically: the gain applied by audio framework ranges from -72dB to 0dB, so an appropriate conversion from linear UI input x to level is: x == 0 -> level = 0 0 < x <= R -> level = 10^(72*(x-R)/20/R)
Parameters levelfloat: send level scalarsetDataSource
Added in API level 24public void setDataSource (AssetFileDescriptor afd)
Sets the data source (AssetFileDescriptor) to use. It is the caller's responsibility to close the file descriptor. It is safe to do so as soon as this call returns.
Parameters afdAssetFileDescriptor: the AssetFileDescriptor for the file you want to play This value cannot benull.Throws IllegalStateExceptionif it is called in an invalid state IllegalArgumentExceptionif afd is not a valid AssetFileDescriptor IOExceptionif afd can not be read setDataSource

Parameters fdFileDescriptor: the FileDescriptor for the file you want to playThrows IllegalStateExceptionif it is called in an invalid state IllegalArgumentExceptionif fd is not a valid FileDescriptor IOExceptionif fd can not be read setDataSource
Added in API level 1public void setDataSource (FileDescriptor fd, long offset, long length)
Sets the data source (FileDescriptor) to use. The FileDescriptor must be seekable (N.B. a LocalSocket is not seekable). It is the caller's responsibility to close the file descriptor. It is safe to do so as soon as this call returns.
Parameters fdFileDescriptor: the FileDescriptor for the file you want to playoffsetlong: the offset into the file where the data to be played starts, in byteslengthlong: the length in bytes of the data to be playedThrows IllegalStateExceptionif it is called in an invalid state IllegalArgumentExceptionif fd is not a valid FileDescriptor IOExceptionif fd can not be read setDataSource
Added in API level 1public void setDataSource (String path)
Sets the data source (file-path or http/rtsp URL) to use.
When
pathrefers to a local file, the file may actually be opened by a process other than the calling application. This implies that the pathname should be an absolute path (as any other process runs with unspecified current working directory), and that the pathname should reference a world-readable file. As an alternative, the application could first open the file for reading, and then use the file descriptor formsetDataSource(java.io.FileDescriptor).Parameters pathString: the path of the file, or the http/rtsp URL of the stream you want to playThrows IllegalStateExceptionif it is called in an invalid state IOExceptionIllegalArgumentExceptionSecurityExceptionsetDataSource
Added in API level 23public void setDataSource (MediaDataSource dataSource)
Sets the data source (MediaDataSource) to use.
Parameters dataSourceMediaDataSource: the MediaDataSource for the media you want to playThrows IllegalStateExceptionif it is called in an invalid state IllegalArgumentExceptionif dataSource is not a valid MediaDataSource setDataSource
Added in API level 26public void setDataSource (Context context, Uri uri, Map<String, String> headers, List<HttpCookie> cookies)
Sets the data source as a content Uri. To provide cookies for the subsequent HTTP requests, you can install your own default cookie handler and use other variants of setDataSource APIs instead. Alternatively, you can use this API to pass the cookies as a list of HttpCookie. If the app has not installed a CookieHandler already, this API creates a CookieManager and populates its CookieStore with the provided cookies. If the app has installed its own handler already, this API requires the handler to be of CookieManager type such that the API can update the manager's CookieStore.
Note that the cross domain redirection is allowed by default, but that can be changed with key/value pairs through the headers parameter with "android-allow-cross-domain-redirect" as the key and "0" or "1" as the value to disallow or allow cross domain redirection.
Parameters contextContext: the Context to use when resolving the Uri This value cannot benull.uriUri: the Content URI of the data you want to play This value cannot benull.headersMap: the headers to be sent together with the request for the data The headers must not include cookies. Instead, use the cookies param. This value may benull.cookiesList: the cookies to be sent together with the request This value may benull.Throws IllegalArgumentExceptionif cookies are provided and the installed handler is not a CookieManager IllegalStateExceptionif it is called in an invalid state NullPointerExceptionif context or uri is null IOExceptionif uri has a file scheme and an I/O error occurs setDataSource
Added in API level 14public void setDataSource (Context context, Uri uri, Map<String, String> headers)
Sets the data source as a content Uri.
Note that the cross domain redirection is allowed by default, but that can be changed with key/value pairs through the headers parameter with "android-allow-cross-domain-redirect" as the key and "0" or "1" as the value to disallow or allow cross domain redirection.
Parameters contextContext: the Context to use when resolving the Uri This value cannot benull.uriUri: the Content URI of the data you want to play This value cannot benull.headersMap: the headers to be sent together with the request for the data This value may benull.Throws IllegalStateExceptionif it is called in an invalid state IOExceptionIllegalArgumentExceptionSecurityExceptionsetDataSource

Added in API level 1public void setDisplay (SurfaceHolder sh)
Sets the
SurfaceHolderto use for displaying the video portion of the media. Either a surface holder or surface must be set if a display or video sink is needed. Not calling this method orsetSurface(android.view.Surface)when playing back a video will result in only the audio track being played. A null surface holder or surface will result in only the audio track being played.Parameters shSurfaceHolder: the SurfaceHolder to use for video displayThrows IllegalStateExceptionif the internal player engine has not been initialized or has been released. setDrmPropertyString
Added in API level 26public void setDrmPropertyString (String propertyName, String value)

Added in API level 1public void setLooping (boolean looping)
Sets the player to be looping or non-looping.
Parameters loopingboolean: whether to loop or notsetNextMediaPlayer
Added in API level 16public void setNextMediaPlayer (MediaPlayer next)
Set the MediaPlayer to start when this MediaPlayer finishes playback (i.e. reaches the end of the stream). The media framework will attempt to transition from this player to the next as seamlessly as possible. The next player can be set at any time before completion, but shall be after setDataSource has been called successfully. The next player must be prepared by the app, and the application should not call start() on it. The next MediaPlayer must be different from 'this'. An exception will be thrown if next == this. The application may call setNextMediaPlayer(null) to indicate no next player should be started at the end of playback. If the current player is looping, it will keep looping and the next player will not be started.
Parameters nextMediaPlayer: the player to start after this one completes playback.setOnBufferingUpdateListener

Added in API level 23public void setPlaybackParams (PlaybackParams params)
Sets playback rate using
PlaybackParams. The object sets its internal PlaybackParams to the input, except that the object remembers previous speed when input speed is zero. This allows the object to resume at previous speed when start() is called. Calling it before the object is prepared does not change the object state. After the object is prepared, calling it with zero speed is equivalent to calling pause(). After the object is prepared, calling it with non-zero speed is equivalent to calling start().Parameters paramsPlaybackParams: the playback params. This value cannot benull.Throws IllegalStateExceptionif the internal player engine has not been initialized or has been released. IllegalArgumentExceptionif params is not supported. setPreferredDevice
Added in API level 28public boolean setPreferredDevice (AudioDeviceInfo deviceInfo)
Specifies an audio device (via an
AudioDeviceInfoobject) to route the output from this MediaPlayer.Parameters deviceInfoAudioDeviceInfo: TheAudioDeviceInfospecifying the audio sink or source. If deviceInfo is null, default routing is restored.Returns booleantrue if succesful, false if the specified AudioDeviceInfois non-null and does not correspond to a valid audio device.setScreenOnWhilePlaying
Added in API level 1public void setScreenOnWhilePlaying (boolean screenOn)
Control whether we should use the attached SurfaceHolder to keep the screen on while video playback is occurring. This is the preferred method over
setWakeMode(Context, int)where possible, since it doesn't require that the application have permission for low-level wake lock access.Parameters screenOnboolean: Supply true to keep the screen on, false to allow it to turn off.setSurface
Added in API level 14public void setSurface (Surface surface)
Sets the
Surfaceto be used as the sink for the video portion of the media. This is similar tosetDisplay(android.view.SurfaceHolder), but does not supportsetScreenOnWhilePlaying(boolean). Setting a Surface will un-set any Surface or SurfaceHolder that was previously set. A null surface will result in only the audio track being played. If the Surface sends frames to aSurfaceTexture, the timestamps returned fromSurfaceTexture.getTimestamp()will have an unspecified zero point. These timestamps cannot be directly compared between different media sources, different instances of the same media source, or multiple runs of the same program. The timestamp is normally monotonically increasing and is unaffected by time-of-day adjustments, but it is reset when the position is set.Parameters surfaceSurface: TheSurfaceto be used for the video portion of the media.Throws IllegalStateExceptionif the internal player engine has not been initialized or has been released. setSyncParams
Added in API level 23public void setSyncParams (SyncParams params)
Sets A/V sync mode.

Added in API level 16public void setVideoScalingMode (int mode)
Sets video scaling mode. To make the target video scaling mode effective during playback, this method must be called after data source is set. If not called, the default video scaling mode is
VIDEO_SCALING_MODE_SCALE_TO_FIT.The supported video scaling modes are:
Parameters modeint: target video scaling mode. Must be one of the supported video scaling modes; otherwise, IllegalArgumentException will be thrown.setVolume
Added in API level 1public void setVolume (float leftVolume, float rightVolume)Sets the volume on this player. This API is recommended for balancing the output of audio streams within an application. Unless you are writing an application to control user settings, this API should be used in preference to
AudioManager.setStreamVolume(int, int, int)which sets the volume of ALL streams of a particular type. Note that the passed volume values are raw scalars in range 0.0 to 1.0. UI controls should be scaled logarithmically.Parameters leftVolumefloat: left volume scalarrightVolumefloat: right volume scalarsetWakeMode
Added in API level 1public void setWakeMode (Context context, int mode)
Set the low-level power management behavior for this MediaPlayer. This can be used when the MediaPlayer is not playing through a SurfaceHolder set with
setDisplay(android.view.SurfaceHolder)and thus can use the high-levelsetScreenOnWhilePlaying(boolean)feature.This function has the MediaPlayer access the low-level power manager service to control the device's power usage while playing is occurring. The parameter is a combination of
PowerManagerwake flags. Use of this method requiresManifest.permission.WAKE_LOCKpermission. By default, no attempt is made to keep the device awake during playback.Parameters contextContext: the Context to usemodeint: the power/wake mode to setSee also:
start
Added in API level 1public void start ()
Starts or resumes playback. If playback had previously been paused, playback will continue from where it was paused. If playback had been stopped, or never started before, playback will start at the beginning.
Throws IllegalStateExceptionif it is called in an invalid state stop
Added in API level 1public void stop ()
Stops playback after playback has been started or paused.
Throws IllegalStateExceptionif the internal player engine has not been initialized. Protected methods
finalize
Added in API level 1protected void finalize ()
Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. A subclass overrides the
finalizemethod to dispose of system resources or to perform other cleanup.The general contract of
finalizeis that it is invoked if and when the Java virtual machine has determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, except as a result of an action taken by the finalization of some other object or class which is ready to be finalized. Thefinalizemethod may take any action, including making this object available again to other threads; the usual purpose offinalize, however, is to perform cleanup actions before the object is irrevocably discarded. For example, the finalize method for an object that represents an input/output connection might perform explicit I/O transactions to break the connection before the object is permanently discarded.The
finalizemethod of classObjectperforms no special action; it simply returns normally. Subclasses ofObjectmay override this definition.The Java programming language does not guarantee which thread will invoke the
finalizemethod for any given object. It is guaranteed, however, that the thread that invokes finalize will not be holding any user-visible synchronization locks when finalize is invoked. If an uncaught exception is thrown by the finalize method, the exception is ignored and finalization of that object terminates.After the
finalizemethod has been invoked for an object, no further action is taken until the Java virtual machine has again determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, including possible actions by other objects or classes which are ready to be finalized, at which point the object may be discarded.The
finalizemethod is never invoked more than once by a Java virtual machine for any given object.Any exception thrown by the
finalizemethod causes the finalization of this object to be halted, but is otherwise ignored.Content and code samples on this page are subject to the licenses described in the Content License. Java and OpenJDK are trademarks or registered trademarks of Oracle and/or its affiliates.
