Failed to create OpenGL ES 3.0 Context

Question

I'm trying to to use GLSL for OpenGL ES 3.0 with OpenGL ES Context 2.0 on Android Emulator Nexus 6 API 24. I declare in my vertex shader and fragment shader with

"#version 300 es"

But I got error: "unsupported shader version". After searching around, I think that maybe changing to OpenGL ES Context 3.0 would solve my problem. Therefore, I edit my GLES3JNIView.java (from this sample: https://github.com/googlesamples/android-ndk/tree/master/gles3jni/app/src/main/java/com/android/gles3jni).

Change the context from 2 to 3 with

setEGLContextClientVersion(3);

and edit the manifest:

< uses-feature android:glEsVersion="0x00030000" android:required="true" />

But I ran into another problem, when I run the app, it crashes on launching. I found these in the logcat:

What am I doing wrong?

OpenGL ES 3.0 isn't supported on the Android emulator.

See:

https://developer.android.com/ndk/guides/stable_apis.html

Specifically:

Note: The Android emulator does not support OpenGL ES 3.0 hardware emulation. Running and testing code that uses this API requires a real device with hardware that can support OpenGL ES 3.0

Thanks for your reply. Btw, I also found this in the given link: Note: The Android emulator does not support OpenGL ES 2.0 hardware emulation. Running and testing code that uses this API requires a real device with hardware that can support OpenGL ES 2.0. However, the example that i use could create OpenGL ES 2.0 Context and declare the OpenGL ES 2.0 in the manifest.xml with no problem. Is this some kind of mistake in the given link or it just doesn't work with GLSL for OpenGL ES 2.0? – Toan Tran Feb 14 '17 at 15:51
