Get GPU info on Android without SurfaceView

问题

On Android, is there a way to get GPU information without creating a SurfaceView? I'm not looking to draw anything using OpenGL, but I just need to get hardware information like vendor, OpenGL ES version, extensions available etc.

I am sorry I am not sure how to do that with Android but the function glGetString allows you to access the OpenGL information. Here is a sample C++ style code that will output the extensions supported by your hardware that I hope you'll be able to adapt to Android:

void PrettyPrintExtensions(){
    std::string extensions = (const char*) glGetString(GL_EXTENSIONS);
    char* extensionStart = &extensions[0];
    char** extension = &extensionStart;
    std::cout << "Supported OpenGL ES Extensions:" << std::endl;
    while (*extension)
        std::cout << '\t' << strsep(extension, " ") << std::endl;
    std::cout << std::endl;
}

By changing the parameter of glGetString you can also access the Vendor, renderer and version. Please see:
