Android Studio: googlemap als Fragment integrieren: Fehler beim Aufblasen des Klassenfragments

Question

Ich versuche, eine Android-App mit einem Folienmenü zu entwickeln, die verschiedene Fragmente lädt. Ein Fragment ist eine Google-Karte.

Wenn die Anwendung gestartet wird, wird das Kartenfragment gut geladen. Aber wenn ich Fragment mit Slidemenu switch und zurück zum Kartenfragment komme, stürzt die Anwendung ab.

Irgendeine Idee? Vielen Dank

bekam ich diese Fehlermeldung in logcat:

Answer 1

private GoogleMap googleMap; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 

      super.onCreate(savedInstanceState); 
      SetupActionBar(); 

      try { 
       setContentView(R.layout.activity_near_by_deals_details); 
       try { 

        context = this; 
        if (googleMap == null) { 
         googleMap = ((MapFragment) getFragmentManager() 
           .findFragmentById(R.id.map)).getMap(); 
        } 
        DrawPoint(pass param if needed); 
     } 


    public void DrawPoint(String param) { 
      googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL); 
      MarkerOptions marker = new MarkerOptions().position(new LatLng(LAT, LON)).title(name); 
      marker.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_ROSE)); 
      googleMap.addMarker(marker); 

      CameraPosition cameraPosition = new CameraPosition.Builder().target(
        new LatLng(LAT, LON)).zoom(15).build(); 

      googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition)); 
      googleMap.getUiSettings().setZoomControlsEnabled(true); 
      googleMap.getUiSettings().setZoomGesturesEnabled(true); 
     } 

Und die XML-Datei:

<LinearLayout 
      android:id="@+id/lnr_deal_detaisl_maps" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:gravity="center" 
      android:orientation="vertical"> 


      <fragment 
       android:id="@+id/map" 
       android:name="com.google.android.gms.maps.MapFragment" 
       android:layout_width="fill_parent" 
       android:layout_height="300dp" 
       android:layout_marginTop="20dp" 
       android:layout_weight="0.92" /> 


    </LinearLayout> 

Above Codes perfekt funktioniert für mich. Hast du dein Manifest überprüft? Google API-Schlüssel funktioniert?
