public class MapsActivity extends FragmentActivity implements OnMapReadyCallback { 

    private GoogleMap mMap; 

    @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. 
     SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager() 
       .findFragmentById(R.id.map); 
     mapFragment.getMapAsync(this); 
    } 


    @Override 
    public void onMapReady(GoogleMap googleMap) { 
     mMap = googleMap; 

     // Add a marker in Sydney and move the camera 
     LatLng sydney = new LatLng(-34, 151); 
     mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney")); 
     mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney)); 
    } 
}

Ihr nächster Fehler, weil ** name == null ** –

Welcher Name? - @ isnotmenow – Rishabh

Sie nicht das ganze Spiel-Services-Bibliothek enthalten, aber die eine, die Sie brauchen, denke ich, dass die Linie zu ersetzen:

compile 'com.google.android.gms:play-services:9.2.0'

mit:

compile 'com.google.android.gms:play-services-maps:9.2.0'

Ihr Problem

lösen sollte

2016-07-21 06:47:02 Signo

es funktionierte, aber jetzt gibt es einen weiteren Fehler – Rishabh

@ Rishabh können Sie den Fehler bei Ihrer Frage posten? – Signo

ja ich habe geschrieben – Rishabh

Im Rahmen der Aktivierung von Google APIs oder Firebase-Diensten in Ihrer Android-Anwendung müssen Sie möglicherweise das google-services-Plugin zu Ihrem root build.grad hinzufügen le Datei:

dependencies { 
    classpath 'com.google.gms:google-services:3.0.0' 
    // ... 
}

Dann an der Unterseite des app/build.gradle hinzufügen:

apply plugin: 'com.google.gms.google-services'
