在设置中开启位置信息后,task.getResult()返回null。如果再试一次就可以了。问题出在哪里?
这是代码:
mFusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(MainActivity.this);
try {
if (mLocationPermissionsGranted) {
Task<Location> location = mFusedLocationProviderClient.getLastLocation();
location.addOnCompleteListener(new OnCompleteListener<Location>() {
@Override
public void onComplete(@NonNull Task<Location> task) {
if (task.isSuccessful()) {
Log.d(TAG, "onComplete: found location!");
currentLocation = task.getResult(); // task.getResult() returns null
if (currentLocation != null) {
moveCamera(new LatLng(currentLocation.getLatitude(), currentLocation.getLongitude()), DEFAULT_ZOOM, "My Location", cameraMovingMode);
}
} else {
Log.d(TAG, "onComplete: current location is null");
Toast.makeText(MainActivity.this, "unable to get current location", Toast.LENGTH_SHORT).show();
}
}
});
}
} catch (SecurityException e) {
Log.e(TAG, "getDeviceLocation: SecurityException: " + e.getMessage());
}
