You could programatically take a screenshot of your device, that should do the trick. Take a look at this SO answer, it should get you started.

You can render different views of your app to Bitmap Objects, by capturing the drawing cache.

just refer to http://blog.neurolive.net/2010/11/385/ for more details. (thx, for the great tutorial)

especially

private Bitmap getScreenViewBitmap(View v) {
    v.setDrawingCacheEnabled(true);

    // this is the important code :)  
    // Without it the view will have a dimension of 0,0 and the bitmap will be null          
    v.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), 
                MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
    v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight()); 

    v.buildDrawingCache(true);
    Bitmap b = Bitmap.createBitmap(v.getDrawingCache());
    v.setDrawingCacheEnabled(false); // clear drawing cache
}

seems what you would be interested in. (Just find your top-level View and use this method to capture the Bitmap)
