Criteria criteria = new Criteria();
                criteria.setAccuracy(Criteria.ACCURACY_FINE);
                Log.d(TAG, "requestSingleUpdate: ");
                locationManager.requestSingleUpdate(criteria, new LocationListener() {
                    @Override
                    public void onLocationChanged(Location location) {
                        callback.onNewLocationAvailable(new GPSCoordinates(location.getLatitude(), location.getLongitude()));
                    }

                    @Override
                    public void onStatusChanged(String provider, int status, Bundle extras) {
                        callback.onSomethingWrong("Status Changed" + status);
                    }

                    @Override
                    public void onProviderEnabled(String provider) {
                        callback.onSomethingWrong("Provider Enabled " + provider);
                    }

                    @Override

LocationManager API,如requestSingleUpdate,对于Oreo来说已经过时了:您必须使用 FusedLocationProviderClient 相反。

google developer tutorials . 特别是对于移民: Migrate to location and context APIs

我的测试证实这个补丁是向后兼容的(同样在Android 6上测试过)

requestSingleUpdate 是 deprecated

使用getCurrentLocation(java.lang.String文件, 安卓操作系统取消信号, java.util.concurrent文件遗嘱执行人, 电池耗尽。

看着 https://medium.com/@priyavrat.acharya01/using-new-on-demand-location-update-api-introduced-in-android-11-69c65b3787aa

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
    // Fetching the one time current location.
    val locationManager: LocationManager = getSystemService(Context.LOCATION_SERVICE) as LocationManager

    // Handle runtime location permission, before calling this method, otherwise it will through the SecurityException.
    // Provider, executor and Consumer<Location> cannot be passed null.
    // CancelationRequest object can be passed as null.          
    locationManager.getCurrentLocation(LocationManager.NETWORK_PROVIDER, null, this.mainExecutor, locationCallback)
} else {
    // Keep using the legacy code, such as LocationManager.requestSingleUpdate()
}

private val locationCallback = Consumer<Location> { location ->
    location?.let {
        Timber.d("Latitude: ${it.latitude.toString()}, longitude: ${it.longitude.toString()}")
    }
}

我没有任何问题 请求SingleUpdate FusedLocationProviderClient . getCurrentLocation 在API 30之前不能工作。
