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

Answer 1

Make sure the icon that you are using for marker should not be vector,it should be .png image.

Answer 2

This exception happens when your marker was reclustered by ClusterManager. ClusterManager recreates marker on clustering. So, to avoid it you must get your marker from render of ClusterManeger:

ClusterIconRender render = (ClusterIconRender) mClusterManager.getRenderer();
Marker trueMarker = render.getMarker(clusterMarker);
if (trueMarker != null) {
    trueMarker.setIcon(...);
    ... // do whatever else your want with marker
}

In code above ClusterMarker implements ClusterItem and ClusterIconRender extends DefaultClusterRenderer.

Answer 3

I found this happening when accessing marker after it was removed. Interacting with marker in callback is exactly that case. As mentioned in Map's API:

After a marker has been removed, the behavior of all its methods is undefined. https://developers.google.com/android/reference/com/google/android/gms/maps/model/Marker.html#remove()

Best option would be checking is marker removed from map or not.
But we don't have such API. And I found another workaround, we can use Marker's setTag and getTag. Tag is set to null, when marker is removed:

Google Maps Android API neither reads nor writes this property, except that when a marker is removed from the map, this property is set to null. https://developers.google.com/android/reference/com/google/android/gms/maps/model/Marker.html#setTag(java.lang.Object)

When creating marker use some tag for it.
When updating marker check tag is not null.

This could help in your case.

@Override
protected void onClusterItemRendered(Sucursal clusterItem, Marker marker) {
    // we don't care about tag's type so don't reset original one
    if (marker.getTag() == null) {
        marker.setTag("anything");
    }
    CustomSimpleTarget simpleTarget = new CustomSimpleTarget();
    simpleTarget.sucursal = clusterItem;
    simpleTarget.markerToChange = marker;
    ImageLoaderManager.setImageFromId(simpleTarget, clusterItem.logo, mContext);
}

And in callback

private class CustomSimpleTarget extends SimpleTarget<GlideDrawable> {
    ...

    @Override
    public void onResourceReady(GlideDrawable resource, GlideAnimation<? super GlideDrawable> glideAnimation) {
        ...

        // if found - change icon
        if (markerToChange != null) {
            //GlideShortcutDrawable is a WeakReference<>(drawable)
            sucursal.setGlideShortCutDrawable(resource);
            if (markerToChange.getTag != null) {
                markerToChange.setIcon(BitmapDescriptorFactory.fromBitmap(icon));
            }
        }
    }
}

Answer 4

I fixed it by calling the following method.

clusterManager.clearItems()

After that, you can set bitmap to the markers.

Answer 5

Marker centerPoint

when you do that： centerPoint.remove();

And then you do it again ：

marker.setIcon(BitmapDescriptorFactory.fromBitmap(bitmap));

It throws an error ：

Unmanaged descriptor

You should centerPoint.remove(); centerPoint=null;

Answer 6

Try

mClusterManager.markerCollection.clear();
mMap.clear()
