How to add a feature in an existing GeodatabaseFeatureTable

[GaelDurand]

I'm trying to add a new feature into an existing GeodatabaseFeatureTable but I get the following error when createFeature is called:

com.esri.arcgisruntime.ArcGISRuntimeException: Cannot call this method in this context

Here is the code:

    // create a new Geodatabase from local path
    mGeodatabase = new Geodatabase(mGeoDb);
    // load the geodatabase
    mGeodatabase.loadAsync();
    // add feature layer from geodatabase to the ArcGISMap
    mGeodatabase.addDoneLoadingListener(new Runnable() {
    @Override
    public void run() {
        for (GeodatabaseFeatureTable geoDbTable : mGeodatabase.getGeodatabaseFeatureTables()){
            java.util.Map<String, Object> attributes = new HashMap<String, Object>();
            attributes.put("COD", "SIG"); 
                
            Point gps = new Point(-1.640235, 48.127568, SpatialReferences.getWgs84());
            Feature addedFeature = geoDbTable.createFeature(attributes, gps);
        }
    }

Any help would be appreciated.

My assumption is that it is probably not fully loaded yet (need to check with that team).  If you put this in at a different time, say after another button click, does it get inserted correctly?

I tried to put the following code in an onClick method long after loading features, but the feature doesn't appear. Do I need to use a SyncGeodatabaseTask? If that is the case, I have no clue how to code it...

java.util.Map<String, Object> attributes2 = new HashMap<String, Object>();
attributes2.put("COD", "SIG"); // Coded Values: [0: No] , [1: Yes]
Point gps = new Point(-1.640235, 48.127568, SpatialReferences.getWgs84());
Feature addedFeature = mGeodatabase.getGeodatabaseFeatureTable("CARTO_ETARE").createFeature(attributes2, gps);
final ListenableFuture<Void> addFeatureFuture = mGeodatabase.getGeodatabaseFeatureTable("CARTO_ETARE").addFeatureAsync(addedFeature);
addFeatureFuture.addDoneListener(new Runnable() {
    @Override
    public void run() {
    }

});
