Android java.lang.VerifyError:拒绝类

当我意识到我的应用程序，许多用户给我发送了一个ANR。所有ANR都来自Android 5.0

java.lang.VerifyError: Rejecting class de.berger.marcus.nwa_app.MapsActivity$2$1 because it failed compile-time verification (declaration of 'de.berger.marcus.nwa_app.MapsActivity$2$1' appears in /data/app/de.berger.marcus.nwa_app-1/base.apk)

MapsActivity.java:181中的我的代码：

if (mapView != null) {
mapView.getMapAsync(new OnMapReadyCallback() {

    @Override
    public void onMapReady(final GoogleMap googleMap) {

        showGPSPreview();
        if (startGPS()==true) {googleMap.setMyLocationEnabled(true);}
        if (startGPS()==false) {Log.d("GPS"," is OFF");}
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(52.33101, 7.91667), 8));

googleMap.setOnMapLoadedCallback(new GoogleMap.OnMapLoadedCallback() {   // THIS IS LINE 181 
@Override
    public void onMapLoaded() {

    CameraPosition cameraPosition = new CameraPosition.Builder()
        .target(new LatLng(52.33101, 7.91667))      // Osnabrück als Zentrum
        .zoom(9)                   // Zoomstufe
        .bearing(0)                // Ausrichtung nach Norden
        .tilt(60)                   // 60 Grad Blickrichtung (Schräge)
        .build();                   // Los geht es

有人给我一只母鹿吗？

好的，我找到了。 我在地图上的物体太多了。我删除了一些后，它就工作了。 但只有在Android 5.0.x上才会出现崩溃
