RangingResultCallback

Kotlin |Java

public abstract class RangingResultCallback
extends Object

java.lang.Object
↳	android.net.wifi.rtt.RangingResultCallback

Base class for ranging result callbacks. Should be extended by applications and set when calling WifiRttManager.startRanging(RangingRequest, java.util.concurrent.Executor, RangingResultCallback). If the ranging operation fails in whole (not attempted) then onRangingFailure(int) will be called with a failure code. If the ranging operation is performed for each of the requested peers then the onRangingResults(java.util.List) will be called with the set of results (@link RangingResult, each of which has its own success/failure code RangingResult.getStatus().

Summary

Constants
`int`	`STATUS_CODE_FAIL` A failure code for the whole ranging request operation.
`int`	`STATUS_CODE_FAIL_RTT_NOT_AVAILABLE` A failure code for the whole ranging request operation.

Public constructors
`RangingResultCallback()`

Public methods
`abstract void`	`onRangingFailure(int code)` Called when a ranging operation failed in whole - i.e.
`abstract void`	`onRangingResults(List<RangingResult> results)` Called when a ranging operation was executed.

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

public static final int STATUS_CODE_FAIL

A failure code for the whole ranging request operation. Indicates a failure.

Constant Value: 1 (0x00000001)

Added in API level 28

public static final int STATUS_CODE_FAIL_RTT_NOT_AVAILABLE

A failure code for the whole ranging request operation. Indicates that the request failed due to RTT not being available - e.g. Wi-Fi was disabled. Use the WifiRttManager.isAvailable() and WifiRttManager.ACTION_WIFI_RTT_STATE_CHANGED to track RTT availability.

Constant Value: 2 (0x00000002)

public RangingResultCallback ()

Added in API level 28

public abstract void onRangingFailure (int code)

Called when a ranging operation failed in whole - i.e. no ranging operation to any of the devices specified in the request was attempted.

Parameters
`code`	`int`: A status code indicating the type of failure. Value is `STATUS_CODE_FAIL`, or `STATUS_CODE_FAIL_RTT_NOT_AVAILABLE`

Added in API level 28

public abstract void onRangingResults (List<RangingResult> results)

Called when a ranging operation was executed. The list of results corresponds to devices specified in the ranging request.

Parameters
`results`	`List`: List of range measurements, one per requested device. This value cannot be `null`.
