I’m compressing some textures using ETC1 when my application starts. I also have a fallback method if ETC1 is not supported.

The problem: 

ETC1Util.isETC1Supported(); // Returns false with no available gl context even if the device supports it.

So my question: Is there a way to query this without a current gl context or I will have to make my splash screen render using a GLSurfaceView in order to get that flag ?

I’ve read that i can filter devices with no such support in AndroidMarket but that is not an option.

    There is no way to query OpenGL extension without OpenGL context.

    But if you use OpenGL ES 2.0, then ETC will always be available there: http://developer.android.com/guide/topics/manifest/supports-gl-texture-element.html

    GL_OES_compressed_ETC1_RGB8_texture

    Ericsson texture compression. Specified in OpenGL ES 2.0 and available in all Android-powered devices that support OpenGL ES 2.0.
