“IBitmapDescriptorFactory is not initialized” error

问题

I'm trying to get a marker with an custom icon in Google Maps Android API v2. I just changed one of the examples Google provides. I added .icon(BitmapDescriptorFactory.fromResource(R.drawable.arrow)) to RawMapViewDemoActivity in method setUpMap().

private void setUpMapIfNeeded() {
    if (mMap == null) {
        mMap = ((MapView) findViewById(R.id.map)).getMap();
        if (mMap != null) {
            setUpMap();
        }
    }
}

private void setUpMap() {
    mMap.addMarker(new MarkerOptions()
        .position(new LatLng(0, 0))
        .title("Marker")
        .icon(BitmapDescriptorFactory.fromResource(R.drawable.arrow)));
}

But I'm always getting an "IBitmapDescriptorFactory is not initialized".

In BitmapDescriptorFactory it says:

Prior to using any methods from this class, you must do one of the following to ensure that this class is initialized:

• Wait for a GoogleMap to become available from a MapFragment or MapView that you have added to your application. You can verify that the GoogleMap is available by calling the getMap() method and checking that the returned object is not null.

• Call MapsInitializer.initialize(Context). As long as a com.google.android.gms.common.GooglePlayServicesNotAvailableException GooglePlayServicesNotAvailableException isn't thrown, this class will be correctly initialized.

I did the first one, but still getting this error. Any suggestions?

回答1:

Call MapsInitializer.initialize(getApplicationContext()) in the onCreate()

回答2:

Call following in onCreate()

try {
        MapsInitializer.initialize(getApplicationContext());
    } catch (GooglePlayServicesNotAvailableException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

回答3:

Move your code to be called onMapReady(), a callback provided by the GoogleMaps API.

回答4:

This happened to me and finally In my case what I could find was the google play services were not installed. So installed them and app did not crash. So may be one can put try and a dialog saying so in the catch block.

回答5:

See Custom marker in google maps in android with vector asset icon.

In my case I had markers over Google Maps. But on API 19 emulator there is a problem with Google Play Services. So this error is misleading, Google Play Services tried to create BitmapDescriptor, but could not.

You should create markers in onMapReady(), also move there any other code, working with Google Maps.

If you have problems with showing Google Maps on Android 4, maybe you should downgrade a library from 16.1.0 to 16.0.0, see https://stackoverflow.com/a/54772374/2914140. But if you do so, you will get a crash on Androif 9, see Google Maps crashing on Android Pie.

回答6:

  GoogleApiAvailability googleApiAvailability=GoogleApiAvailability.getInstance();

  int status=googleApiAvailability.isGooglePlayServicesAvailable(getActivity());



  if (status != ConnectionResult.SUCCESS) {
        int requestCode = 10;
        Dialog dialog = googleApiAvailability.getErrorDialog(getActivity(),status,requestCode);
        dialog.show();
    }else {}
