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`.
