我的谷歌地图Android应用程序不能在三星手机上运行，​​但它在其他手机品牌上运行

Question

这是我的代码MapsActivity.java文件，请参阅 我的代码不是在三星手机上运行，​​而是在所有手机中运行。我很困惑我应该怎么做代码。

public class MapsActivity extends FragmentActivity {

    private GoogleMap mMap;
    private GoogleApiClient client;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        setUpMapIfNeeded();

        client = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build();

    }

    @Override
    protected void onResume() {
        super.onResume();
        setUpMapIfNeeded();
    }

    public void onSearch(View view) {
        EditText location_tf = (EditText) findViewById(R.id.TFaddress);
        String location = location_tf.getText().toString();
        List<android.location.Address> addressList = null;
        if (location != null || !location.equals("")) {
            Geocoder geocoder = new Geocoder(this);
            try {
                addressList = geocoder.getFromLocationName(location, 1);
            } catch (IOException e) {
                e.printStackTrace();
            }
            android.location.Address address = addressList.get(0);
            LatLng latLng = new LatLng(address.getLatitude(), address.getLongitude());
            mMap.addMarker(new MarkerOptions().position(latLng).title("Marker"));


            mMap.animateCamera(CameraUpdateFactory.newLatLng(latLng));
        }
    }


    public void changeType(View view) {
        if (mMap.getMapType() == GoogleMap.MAP_TYPE_NORMAL) {
            mMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
        } else
            mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
    }

    private void setUpMapIfNeeded() {

        if (mMap == null) {
            mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
                    .getMap();
            if (mMap != null) {
                setUpMap();
            }
        }
    }

    private void setUpMap() {
        mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker"));
        mMap.setMyLocationEnabled(true);
        mMap.getUiSettings().setZoomControlsEnabled(true);
        mMap.getUiSettings().setIndoorLevelPickerEnabled(true);

        LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

        Criteria criteria = new Criteria();

        String provider = locationManager.getBestProvider(criteria, true);

        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

            return;
        }
        Location myLocation = locationManager.getLastKnownLocation(provider);

        mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);

        double latitude = myLocation.getLatitude();

        double longitude = myLocation.getLongitude();

        LatLng latLng = new LatLng(latitude, longitude);

        CameraPosition cameraPosition = new CameraPosition.Builder()
            .target(latLng)      
            .zoom(12)               
            .build();                  
        mMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));

        mMap.addMarker(new MarkerOptions().position(new LatLng(latitude, longitude)).title("You are here!").snippet("Consider yourself located"));

    }

}

我的谷歌地图Android应用程序不能在三星手机上运行，​​但它在其他手机品牌上运行。有什么问题？
