IllegalArgumentException: Unmanaged descriptor using gms.maps.model.Marker.setIcon

Question

I have an app that use android-maps-utils and glide for marker icons.
I got an error report using Firebase crash reporting which I can\'t track in source code because

I have the same environment (maps-utils + custom renderer + Glide) and the same error IllegalArgumentException: Unmanaged descriptor.

I solved the error by checking if the marker is "valid" before setting the icon, using the methods DefaultClusterRenderer.getCluster(Marker) and DefaultClusterRenderer.getClusterItem(Marker). If both return null, I don't do anything on the onResourceReady(...) method.

In your case I would try the following change to CustomSimpleTarget:

private class CustomSimpleTarget extends SimpleTarget {
    Sucursal sucursal;
    Marker markerToChange = null;

    @Override
    public void onResourceReady(GlideDrawable resource, GlideAnimation glideAnimation) {

        if (getCluster(markerToChange) != null || getClusterItem(markerToChange) != null) {

            mImageView.setImageDrawable(resource);
            //currentSelectedItem is the current element selected in the map (Sucursal type)
            //mIconGenerator is a: CustomIconGenerator extends IconGenerator
            if (currentSelectedItem != null && sucursal.idalmacen.contentEquals(currentSelectedItem.idalmacen))
                mIconGenerator.customIconBackground.useSelectionColor(true, ContextCompat.getColor(mContext, R.color.colorAccent));
            else
                mIconGenerator.customIconBackground.useSelectionColor(false, 0);

            Bitmap icon = mIconGenerator.makeIcon();

            //GlideShortcutDrawable is a WeakReference<>(drawable)
            sucursal.setGlideShortCutDrawable(resource);
            markerToChange.setIcon(BitmapDescriptorFactory.fromBitmap(icon));
        }
    }
}

PS.: I can reproduce the problem easily on a slow device and clearing the app cache before testing (to force Glide to load from network). Then I open the map and perform some zoom in/out before any markers load.
