As written in the title, I'm trying to create an android live wallpaper using unity3d. Unfortunately, I can't find any information on how to do that.
After doing a lot of research, trials and errors, I finally managed to make it work. For those who are interested in running or trying to create Android live wallpapers on Unity3D I created a GitHub Unity3dAndroidLiveWallpaper project that you can use as a base for your own projects. I only tested this project on Unity 2018.3.5f1, but any versions above 2018.3 should work, because since that version Unity allows you to add .java files into your Unity project and they are compiled when you build an Android player. Because of that Android Studio is not required to compile this project.
