Hi everybody ! I'm currently working on an app that will display a GMap view inside Unity. So i have to use the Android SDK of GMaps with Android Studio to create a plugin that'll do the trick. But I ran into a problem that get me stuck for a while, when I try to call my plugin inside Unity with Code (CSharp): AndroidJavaClass _class = new AndroidJavaClass ("net.tuttifruttigames.mapsplugin.MapsPlugin"); I have this error : AndroidJavaException: java.lang.ClassNotFoundException: net.tuttifruttigames.mapsplugin.MapsPlugin. The definition of my java class is : Code (CSharp): package net.tuttifruttigames.mapsplugin; public class MapsPlugin extends FragmentActivity implements OnMapReadyCallback I followed this tutorial http://eppz.eu/blog/unity-android-plugin-tutorial-2/ to do a basic Android plugin (that was working), then I customized it to display a map (that is not working). This allowed me to found the problem come from the classes FragmentActivity and OnMapReadyCallback. If I remove both of them, my class is found by Unity but I need to implement and extend them to display my map. So I'm kind of stuck since I didn't find any satisfying answer on the forums. Does anyone know where this problem can come from and how to solve it? Thanks !
