                         ApplicationInfo info;

                            try {

                                info = p.getApplicationInfo(myPackage, );

                                draw=info.loadIcon(p);

                            } catch (NameNotFoundException e) {

                                // TODO Auto-generated catch block

                                e.printStackTrace();

                            }

    public static  Bitmap drawableToBitmap(Drawable drawable) {

        Bitmap bitmap = Bitmap.createBitmap(

                                        drawable.getIntrinsicWidth(),

                                        drawable.getIntrinsicHeight(),

                                        drawable.getOpacity() != PixelFormat.OPAQUE ? Bitmap.Config.ARGB_8888

                                                        : Bitmap.Config.RGB_565);

        Canvas canvas = new Canvas(bitmap);

        //canvas.setBitmap(bitmap);

        drawable.setBounds(, , drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());

        drawable.draw(canvas);

        return bitmap;
