Example OpenGLES2 Android app for an Android phone and Android Things Rpi3 Device using Developer Preview 4.1, 5.1, 6.0
Just playing about trying to learn opengles2 using Android Things on the Raspberry Pi. Any help or input is much appreciated. It's a very simple app to display (a simplified) Maxwell's colour triangle.
Please note this app comes in 4 flavours: phone, Android Things 41, Android Things 51 and Android Things 60
v1.1: The code is now running on Android Things DP60. I'd recommend you upgrade to Dev Preview 6.0.
as there are some ghosting issues using DP51 and some hdmi screens.
Android 41 is not hardware accelerated and therefore unlikey to work but I made it for completeness. The phone flavour does work and indicates the code is valid in a general sense and just highlights the ghosting issue in DP51.
