Games on Andriod OpenGL ES 2.0 support

GPU Option with Android Virtual Device. Exceptions cases and Solution

Android 4.2.2 ( API 17 )
Debugging with Android Virutal Device

FATAL EXCEPTION: GLThread 75
java.lang.IllegalArgumentException: No configs match configSpec
at android.opengl.GLSurfaceView$BaseConfigChooser.chooseConfig(GLSurfaceView.java:863)
at android.opengl.GLSurfaceView$EglHelper.start(GLSurfaceView.java:1024)
at android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1401)
at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1240)

The above exception occurs for the following below casea . The code ( for the Category.LAUNCHER class ) + emulator configuration for each case is given below

CASE-1 #

Code that throws the above exception

Code:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.d(this.getClass().getName(), "Into onCreate Draw triangle");
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        requestWindowFeature(Window.FEATURE_NO_TITLE);

        if (detectOpenGLES20()){

            Log.d("GLES20", "GL ES 2.0 Supported..............!");

          } else {

            Log.d("GLES20", "GL ES 2.0 Not Supported...............!");

          }

        view = new GLSurfaceView(this);
        view.setEGLContextClientVersion(2);
        view.setEGLConfigChooser(true);
        view.setRenderer(new TriangleRenderer(view));
        setContentView(view);
    }

Emulator configuration:

In the 'Edit Android Virtual Device' windoow
'Snapshot' is unchekced and 'Use Host GPU' are unchecked

CASE-2 #

This is same as CASE-1# except 'Use Host GPU' checkbox is CHECKED
This option can be edited in the Eclipse --> 'Edit Android Virtual Device' windoow ---> 'Use Host GPU'

In this Case we still get an IllegalArgumentException but with a different error message ( 'No config chosen' ) and also from different part the andriod.opengl.GLSurfaceViewBaseConfigChooser class



Exception:

java.lang.IllegalArgumentException: No config chosen
:     at Android.opengl.GLSurfaceView$BaseConfigChooser.chooseConfig(GLSurfaceView.java:874)

Code:

    public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            Log.d(this.getClass().getName(), "Into onCreate Draw triangle");
            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
            requestWindowFeature(Window.FEATURE_NO_TITLE);

            if (detectOpenGLES20()){

                Log.d("GLES20", "GL ES 2.0 Supported..............!");

              } else {

                Log.d("GLES20", "GL ES 2.0 Not Supported...............!");

              }

            view = new GLSurfaceView(this);
            view.setEGLContextClientVersion(2);
            view.setEGLConfigChooser(true);
            view.setRenderer(new TriangleRenderer(view));
            setContentView(view);
        }

Emulator configuration:
In the 'Edit Android Virtual Device' windoow

'Snapshot' and 'Use Host GPU' checkboxes is CHECKED

CASE-3 #

This is same as CASE-2# except the an additional '-gpu on' is present in the Emulator Launch Command Line Options

This option can be edited in the Eclipse --> Run as ---> Target ---> Additional Emulator Command Line Options

In this Case we still get an IllegalArgumentException but with a different error message ( 'No config chosen' ) and also from different part the andriod.opengl.GLSurfaceViewBaseConfigChooser class



Exception:

: java.lang.IllegalArgumentException: No config chosen
:     at android.opengl.GLSurfaceView$BaseConfigChooser.chooseConfig(GLSurfaceView.java:874)

Code:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

                 getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

                view.setRenderer(new TriangleRenderer(view));
                setContentView(view);
            }

Emulator configuration:
In the 'Edit Android Virtual Device' windoow

'Snapshot' and 'Use Host GPU' checkboxes is CHECKED

Emulator Launch Command line options:
-gpu on

SOLUTION

None of the Above three CASES# solve the problem
The problem gets RESOLVED by two steps below

a.) Adding an extra line of code: view.setEGLConfigChooser(8 , 8, 8, 8, 16, 0);

b.) setting '-gpu on' via Eclipse --> Run as ---> Target ---> Additional Emulator Command Line Options


Code:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.d(this.getClass().getName(), "Into onCreate Draw triangle");
            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
            requestWindowFeature(Window.FEATURE_NO_TITLE);

            if (detectOpenGLES20()){

                Log.d("GLES20", "GL ES 2.0 Supported..............!");

              } else {

                Log.d("GLES20", "GL ES 2.0 Not Supported...............!");

              }

            view = new GLSurfaceView(this);
            view.setEGLContextClientVersion(2);
            view.setEGLConfigChooser(8 , 8, 8, 8, 16, 0);
            view.setRenderer(new TriangleRenderer(view));
            setContentView(view);
    }
