Mapbox-gl-native: java.lang.NullPointerException: Attempt to invoke virtual method 'android.graphics.Bitmap$Config android.graphics.Bitmap.getConfig()' on a null object reference

[Noxagon]

I don't quite get this still, anyone can help out?

Here's my code:

public Bitmap getBitmap() {
        Bitmap mBitmap = BitmapFactory.decodeResource(this.getResources(), R.drawable.ic_marker_orange);

        if (mBitmap != null && mBitmap.getConfig() != Bitmap.Config.ARGB_8888) {
            mBitmap = mBitmap.copy(Bitmap.Config.ARGB_8888, false);
        }
        return mBitmap;
    }

    private void setUpImage(@NonNull Style loadedMapStyle) {
        loadedMapStyle.addImage(MARKER_IMAGE_ID, getBitmap());
    }

Error:

@Noxagon thank you for reaching out and using our products. Can you confirm that R.drawable.ic_marker_orange is a vector drawable? decodeResource will only work for bitmap drawable.

I was able to reproduce the same NullPointerException using a vector drawable. Using following code mitigates the crash:

    Drawable drawable = ResourcesCompat.getDrawable(getResources(), R.drawable.ic_my_location, null);
    Bitmap mBitmap = BitmapUtils.getBitmapFromDrawable(drawable);

great to hear @Noxagon, closing as resolved
