I'm having to do some GL work with Android and I thought I'd share some code for querying your GL driver for it's complete list of configurations.

import javax.microedition.khronos.egl.*;
import android.util.Log;

...

EGL10 egl = (EGL10)EGLContext.getEGL();
EGLDisplay dpy = egl.eglGetDisplay(EGL10.EGL_DEFAULT_DISPLAY);

int[] version = new int[2];
egl.eglInitialize(dpy, version);

EGLConfig[] conf = new EGLConfig[100];
int[] num_conf = new int[100];
egl.eglGetConfigs(dpy, conf, 100, num_conf);

for(int i = 0; i < 100; i++)
{
	int[] value = new int[1];
	
	if (conf[i] != null)
	{
    	
		Log.v("ANDROID", String.format("conf[%d] = %s", i, conf[i].toString() ) );
		
		egl.eglGetConfigAttrib(dpy, conf[i], EGL10.EGL_RED_SIZE, value);
		Log.v("ANDROID", String.format("EGL_RED_SIZE  = %d", value[0] ) );
		
		egl.eglGetConfigAttrib(dpy, conf[i], EGL10.EGL_BLUE_SIZE, value);
		Log.v("ANDROID", String.format("EGL_BLUE_SIZE  = %d", value[0] ) );

		egl.eglGetConfigAttrib(dpy, conf[i], EGL10.EGL_GREEN_SIZE, value);
		Log.v("ANDROID", String.format("EGL_GREEN_SIZE  = %d", value[0] ) );

		egl.eglGetConfigAttrib(dpy, conf[i], EGL10.EGL_ALPHA_SIZE, value);
		Log.v("ANDROID", String.format("EGL_ALPHA_SIZE  = %d", value[0] ) );
		
		egl.eglGetConfigAttrib(dpy, conf[i], EGL10.EGL_DEPTH_SIZE, value);
		Log.v("ANDROID", String.format("EGL_DEPTH_SIZE  = %d", value[0] ) );
		
		egl.eglGetConfigAttrib(dpy, conf[i], EGL10.EGL_ALPHA_FORMAT, value);
		Log.v("ANDROID", String.format("EGL_ALPHA_FORMAT  = %d", value[0] ) );
		
		egl.eglGetConfigAttrib(dpy, conf[i], EGL10.EGL_ALPHA_MASK_SIZE, value);
		Log.v("ANDROID", String.format("EGL_ALPHA_MASK_SIZE  = %d", value[0] ) );
							
	}
	else
	{
		break;
	}
}
