0down votefavorite I have two Feature Layers added into a Map that I can see when I display the MapView. However, it's only the last added Feature Layer that can be processed by the Touch Listener. I cannot figure out how to make all Features Layers taken into account by the Touch Listener. My goal is to differentiate a click on a CARTO_ETARE's feature from a click on a CARTO_PT_EAU's one. Any help would be appreciated. import android.Manifest; import android.content.pm.PackageManager; import android.graphics.Color; import android.os.Bundle; import android.os.Environment; import android.support.v7.app.AppCompatActivity;
