PixelCopy

ERROR_DESTINATION_INVALID

public static final int ERROR_DESTINATION_INVALID

The destination isn't a valid copy target. If the destination is a bitmap this can occur if the bitmap is too large for the hardware to copy to. It can also occur if the destination has been destroyed.

Constant Value: 5 (0x00000005)

ERROR_SOURCE_INVALID

public static final int ERROR_SOURCE_INVALID

It is not possible to copy from the source. This can happen if the source is hardware-protected or destroyed.

Constant Value: 4 (0x00000004)

ERROR_SOURCE_NO_DATA

public static final int ERROR_SOURCE_NO_DATA

The source has nothing to copy from. When the source is a Surface this means that no buffers have been queued yet. Wait for the source to produce a frame and try again.

Constant Value: 3 (0x00000003)

ERROR_TIMEOUT

public static final int ERROR_TIMEOUT

A timeout occurred while trying to acquire a buffer from the source to copy from.

Constant Value: 2 (0x00000002)

ERROR_UNKNOWN

public static final int ERROR_UNKNOWN

The pixel copy request failed with an unknown error.

Constant Value: 1 (0x00000001)

SUCCESS

public static final int SUCCESS

The pixel copy request succeeded

Constant Value: 0 (0x00000000)

request

public static void request (SurfaceView source, 
                Bitmap dest, 
                PixelCopy.OnPixelCopyFinishedListener listener, 
                Handler listenerThread)

Requests for the display content of a SurfaceView to be copied into a provided Bitmap. The contents of the source will be scaled to fit exactly inside the bitmap. The pixel format of the source buffer will be converted, as part of the copy, to fit the bitmap's Bitmap.Config. The most recently queued buffer in the SurfaceView's Surface will be used as the source of the copy.

public static void request (Surface source, 
                Rect srcRect,

                PixelCopy.OnPixelCopyFinishedListener listener, 
                Handler listenerThread)

Requests a copy of the pixels at the provided Rect from a Surface to be copied into a provided Bitmap. The contents of the source rect will be scaled to fit exactly inside the bitmap. The pixel format of the source buffer will be converted, as part of the copy, to fit the bitmap's Bitmap.Config. The most recently queued buffer in the Surface will be used as the source of the copy.

Requests for the display content of a SurfaceView to be copied into a provided Bitmap. The contents of the source will be scaled to fit exactly inside the bitmap. The pixel format of the source buffer will be converted, as part of the copy, to fit the bitmap's Bitmap.Config.

request

public static void request (Window source, 
                Rect srcRect, 
                Bitmap dest, 
                PixelCopy.OnPixelCopyFinishedListener listener, 
                Handler listenerThread)

Requests a copy of the pixels at the provided Rect from a Window to be copied into a provided Bitmap. The contents of the source rect will be scaled to fit exactly inside the bitmap. The pixel format of the source buffer will be converted, as part of the copy, to fit the bitmap's Bitmap.Config. The most recently queued buffer in the Window's Surface will be used as the source of the copy. Note: This is limited to being able to copy from Window's with a non-null DecorView. If Window#peekDecorView() is null this throws an IllegalArgumentException. It will similarly throw an exception if the DecorView has not yet acquired a backing surface. It is recommended that OnDrawListener is used to ensure that at least one draw has happened before trying to copy from the window, otherwise either an IllegalArgumentException will be thrown or an error will be returned to the OnPixelCopyFinishedListener.
