Is it possible to debug shaders in Android OpenGL ES 2?

Question

Is there a possibility to debug the shaders (fragment and vertex) in an Android Application with OpenGL-ES 2?

Since we only pass a String with code and a bunch of variables to replace with handles, it is very tedious to find the proper changes that need to be done.

• Is it possible to write to the Android Log, as in Log.d()

• Is it possible to use break points and to inspect the current values in the shader calculations?

I am simply not used to write code with a pen anymore and that's what it feels like to code within the shader text code.

否。请记住，GPU将执行每个程序数百万次（每个顶点一次，每个片段一次），通常同时运行数百个线程，因此几乎没有“连接调试器”的概念。
