Following the example given here, I created the application, I have 2 files here (activity_main.xml and activity_maps.xml). In the end, I inserted a code snippet into content_main.

When you start the application through the phone, the application crashes and writes “Application Stopped”. What is the problem?

Here is a crash:

12-17 22: 59: 15.899 1719-1719 /? E / NotificationService: WARNING: In a future release: this will crash the app: com.android.providers.downloads

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback { static final LatLng TutorialsPoint = new LatLng(21 , 57); private GoogleMap googleMap; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_maps); // Obtain the SupportMapFragment and get notified when the map is ready to be used. try { if (googleMap == null) { googleMap = ((MapFragment) getFragmentManager(). findFragmentById(R.id.map)).getMap(); } googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID); Marker TP = googleMap.addMarker(new MarkerOptions(). position(TutorialsPoint).title("TutorialsPoint")); } catch (Exception e) { e.printStackTrace(); } } /** * Manipulates the map once available. * This callback is triggered when the map is ready to be used. * This is where we can add markers or lines, add listeners or move the camera. In this case, * we just add a marker near Sydney, Australia. * If Google Play services is not installed on the device, the user will be prompted to install * it inside the SupportMapFragment.

    You already asked to attach the code. The application stops due to an error, and the error can be anywhere. Initializing GoogleMap is the place where you implement it. - Eugene Troyanskii
  • Do you mean it? - No Name
  • How is "As a result, I inserted a code fragment in content_main" and the fact that your markup is still from activity_maps? - Android Android
  • Oh, I apologize, corrected ... I just had the content first and then changed it to activate_meps the same problem remained ... - No Name
  • I'll check just in case. You got and added a key for Google maps? - Eugene Troyanskii

To solve your problem try this:

 String uri = String.format(Locale.ENGLISH, "http://maps.google.com/maps?saddr=%f,%f(%s)&daddr=%f,%f (%s)", sourceLatitude, sourceLongitude, "Home Sweet Home", destinationLatitude, destinationLongitude, "Where the party is at"); Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri)); intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity"); startActivity(intent);

Although for the flexibility of your application, I would still recommend that you carefully go through the tutorial on installing google maps https://developers.google.com/maps/documentation/android-api/start . You obviously missed some kind of in your opinion not an important detail that you did not attach to the question.
