: Developers can "mix and match" vertex and fragment programs without a strict linking step, increasing flexibility and productivity.

In conclusion, OpenGL ES 3.1 is a powerful and widely used API for 3D graphics rendering on Android. Its features, such as programmable pipeline, vertex and fragment shaders, and texture support, make it suitable for demanding 3D graphics applications. By using OpenGL ES 3.1 on Android, developers can create high-performance, low-power 3D graphics applications that run on a wide range of devices.

If you require 3.1 specifically, you must request it during configuration.

Because many "top" cross-engine solutions (Unity's Built-in Render Pipeline, Cocos Creator) still rely heavily on ES 3.1 as their high-end fallback. Furthermore, maintenance of legacy codebases requires ES 3.1 expertise.

Draw scene to FBO → CPU reads depth → CPU ping-pong textures → Too slow.

Add the following to your AndroidManifest.xml to ensure your app is only installed on compatible devices:
