Question

Hi After setting wall paper in Android 1.6 using code

Context context = ImageSwitcher2.this.getBaseContext(); 
Bitmap mBitmap = BitmapFactory.decodeResource(getResources(),
                    mImageIds[pos]);
context.setWallpaper(mBitmap);

sets the wallpaper. But on the home screen on Android 1.6 device screen gets blurred on doing any action.
