There was a need to integrate a google map into the project, put it on the google MapFragment guide, hadn’t had a deal with google maps before, checked yesterday on the phone (Samsung Galaxy S4) - the fragment opens and displays the map correctly. The GoogleMaps API on google is activated, the Api key is registered in the manifest. An activity in which fragments are launched is inherited from AppCompatActivity. When you try to go to the fragment with a map on the emulator built into the studio (Nexus 4 21 API (with GoogleAPIs) and Nexus 4 23 API (with GoogleAPIs), the application crashes.

Question: What can be done to run the map fragment correctly and display the maps on the emulator?

I enclose the error of the error, the complete code of the fragment, and partly the layout, the manifest and Build.gradle.

  • @AndroidAndroid Installed on the emulator with 23 API com.android.vending.apk (v6.0.0) and com.google.android.gms.apk (v8.3.01), now before the departure of the emulator writes: "unfortunately google services has stopped", the same thing he writes when starting the store - rockon

Solved the problem as follows. First, I changed the code of the fragment class so that the application does not crash on API versions 21 and higher:

 public class OrdersFragmentMap extends Fragment implements OnMapReadyCallback, LoaderManager.LoaderCallbacks<Cursor> { ArrayList<Order> freeOrders = new ArrayList<>(); ArrayList<Order> myOrders = new ArrayList<>(); private FragmentActivity myContext; public static OrdersFragmentMap newInstance() { return new OrdersFragmentMap(); } public OrdersFragmentMap() { } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.courier_fragment_map, container, false); FragmentManager fm = myContext.getSupportFragmentManager(); SupportMapFragment mapFragment = SupportMapFragment.newInstance(); fm.beginTransaction().replace(R.id.map, mapFragment).commit(); mapFragment.getMapAsync(this); return view; } @Override public void onMapReady(GoogleMap googleMap) { LatLng sydney = new LatLng(-33.867, 151.506); googleMap.setMyLocationEnabled(true); googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(sydney, 13)); googleMap.addMarker(new MarkerOptions().title("Sydney").snippet( "The most populous city in Australia.").position(sydney)); } @Override public void onResume() { super.onResume(); } @Override public void onDestroy() { super.onDestroy(); } @Override public void onLowMemory() { super.onLowMemory(); } @Override public void onAttach(Activity activity) { myContext=(FragmentActivity) activity; super.onAttach(activity);

The onAttach () method is obsolete and I use it temporarily only to run android.support.v4.app.FragmentManager in the AppCompatActivity.

Secondly, I created a MapActivity template. To do this, right-click in the project root and select new> Google> GoogleMapsActivity. Of the three files created, I left only res / values ​​/ google_maps_api.xml (debug), copied from it a link to generate the key that is in the comment, followed it in the browser, created the key and it all worked. The strangest thing is that before this he introduced the same fingerprint and package name. Such are the cases.

And on the Galaxy S4 API it worked, apparently, bypassing Google protection, since there were no requests in the developer console while the application was running.
