我尝试编写示例代码以在我的应用程序中测试Google Maps API。一切看起来都不错，但是当我从应用程序中打开Google地图时，它将停止工作。
请给我一些帮助。
public class SmarttreenearbyActivity extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_smarttreenearby);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
mMap.setMyLocationEnabled(true);
// Add a marker in Sydney and move the camera
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria();
String provider = locationManager.getBestProvider(criteria, true);
Location location = locationManager.getLastKnownLocation(provider);
double y = location.getLatitude();
double x = location.getLongitude();
LatLng sydney = new LatLng(x,y);
mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}
}
尝试使用FusedLocationApi。这是一个官方的Google API，它使我们能够获取位置，而无需自己创建复杂的位置逻辑。
