public static void getCurrentLocation(
    @NonNull LocationManager locationManager,
    @NonNull String provider,
    @Nullable CancellationSignal cancellationSignal,
    @NonNull Executor executor,
    @NonNull Consumer<Location> consumer
)

Asynchronously returns a single current location fix from the given provider. This may activate sensors in order to compute a new location. The given callback will be invoked once and only once, either with a valid location or with a null location if the provider was unable to generate a valid location.

A client may supply an optional CancellationSignal. If this is used to cancel the operation, no callback should be expected after the cancellation.

This method may return locations from the very recent past (on the order of several seconds), but will never return older locations (for example, several minutes old or older). Clients may rely upon the guarantee that if this method returns a location, it will represent the best estimation of the location of the device in the present moment.

Clients calling this method from the background may notice that the method fails to determine a valid location fix more often than while in the foreground. Background applications may be throttled in their location accesses to some degree.

public static @Nullable String getGnssHardwareModelName(@NonNull LocationManager locationManager)

Returns the model name (including vendor and hardware/software version) of the GNSS hardware driver, or null if this information is not available.

No device-specific serial number or ID is returned from this API.

public static int getGnssYearOfHardware(@NonNull LocationManager locationManager)

Returns the model year of the GNSS hardware and software build, or 0 if the model year is before 2016.

public static boolean hasProvider(
    @NonNull LocationManager locationManager,
    @NonNull String provider
)

Returns true if the given location provider exists on this device, irrespective of whether it is currently enabled or not. If called on Android Q and below for the FUSED_PROVIDER, this method may return incorrect results if the client does not hold at least the ACCESS_COARSE_LOCATION permission.

public static boolean isLocationEnabled(@NonNull LocationManager locationManager)

Returns the current enabled/disabled state of location.

NOTE: Calling this method on API levels prior to 20 may require the ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION permission if run on non-standard Android devices. The vast majority of devices should not require either permission to be present for this method.

public static boolean registerGnssMeasurementsCallback(

)

Registers a GNSS measurement callback. See registerGnssMeasurementsCallback.

The primary purpose for this compatibility method is to help avoid crashes when delivering GNSS measurements to client on Android R. This bug was fixed in Android R QPR1, but since it's possible not all Android R devices have upgraded to QPR1, this compatibility method is provided to ensure GNSS measurements can be delivered successfully on all platforms.

public static boolean registerGnssMeasurementsCallback(
    @NonNull LocationManager locationManager,
    @NonNull Executor executor,
    @NonNull GnssMeasurementsEvent.Callback callback
)

Registers a GNSS measurement callback. See registerGnssMeasurementsCallback.

In addition to allowing the use of Executors on older platforms, this compatibility method also helps avoid crashes when delivering GNSS measurements to clients on Android R. This bug was fixed in Android R QPR1, but since it's possible not all Android R devices have upgraded to QPR1, this compatibility method is provided to ensure GNSS measurements can be delivered successfully on all platforms.

public static boolean registerGnssStatusCallback(
    @NonNull LocationManager locationManager,
    @NonNull GnssStatusCompat.Callback callback,
    @NonNull Handler handler
)

Registers a platform agnostic GnssStatusCompat.Callback. See addGpsStatusListener and registerGnssStatusCallback.

public static boolean registerGnssStatusCallback(
    @NonNull LocationManager locationManager,
    @NonNull Executor executor,
    @NonNull GnssStatusCompat.Callback callback
)

Registers a platform agnostic GnssStatusCompat.Callback. See addGpsStatusListener and registerGnssStatusCallback.

Internally, this API will always utilize GnssStatus APIs and instances on Android N and above, and will always utilize GpsStatus APIs and instances below Android N. Callbacks will always occur on the given executor.

If invoked on Android M or below, this will result in GpsStatus registration being run on either the current Looper or main Looper. If the thread this function is invoked on is different from that Looper, the caller must ensure that the Looper thread cannot be blocked by the thread this function is invoked on. The easiest way to avoid this is to ensure this function is invoked on a Looper thread.

public static void removeUpdates(
    @NonNull LocationManager locationManager,

)

Register for location updates from the specified provider, using a LocationRequestCompat, and a callback on the specified Executor.

See requestLocationUpdates for more information.

@RequiresApi(value = VERSION_CODES.N)
public static void unregisterGnssMeasurementsCallback(
