Question

What is the different beetween this, and how i can query what is supported by the actual phone? (GL10 or GL11)

Or hero…etc… ?

Answer 1

There’s an API for that:

public int getGLVersion() 
{
    ActivityManager am = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
    ConfigurationInfo info = am.getDeviceConfigurationInfo();
    return info.reqGlEsVersion;
}

The upper order 16 bits represent the major version and the lower order 16 bits the minor version. For more information, visit this link.
So:

• For OpenGLES 1.1, getGLVersion() == 0x00010001
• For OpenGLES 2.0, getGLVersion() == 0x00020000

If you want the string representation (for display), call ConfigurationInfo.getGlEsVersion()
