Moving MapFragment (SurfaceView) causes black background flickering

Question

I\'m trying to implement new Android Google Maps API (v2). However it doesn\'t seem to go well with SlidingMenu. As you may know, MapFragment implementation is

Taking screenshot of a map isn't possible, but maybe someone will get inspired by this.

It's possible with the snapshot interface from GoogleMap. Now you can display a snapshot of the map while scrolling the page. With this I solved my problem with the ViewPager, maybe you can change the code to fit your SlidingMenu.

Here is my code to setting the snapshot (it's in the same fragment as map, called FragmentMap.java):

public void setSnapshot(int visibility) {
    switch(visibility) {
    case View.GONE:
        if(mapFragment.getView().getVisibility() == View.VISIBLE) {
            getMap().snapshot(new SnapshotReadyCallback() {
                @Override
                public void onSnapshotReady(Bitmap arg0) {
                    iv.setImageBitmap(arg0);
                }
            });
            iv.setVisibility(View.VISIBLE);
            mapFragment.getView().setVisibility(View.GONE);
        }
        break;
    case View.VISIBLE:
        if(mapFragment.getView().getVisibility() == View.GONE) {
            mapFragment.getView().setVisibility(View.VISIBLE);
            iv.setVisibility(View.GONE);
        }
        break;
    }
}

Where "mapFragment" is my SupportedMapFragment and "iv" is an ImageView (make it match_parent).

And here I am controlling the scroll:

pager.setOnPageChangeListener(new OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
            if(position == 0 && positionOffsetPixels > 0 || position == 1 && positionOffsetPixels > 0) {
                ((FragmentMap)adapter.getRegisteredFragment(1)).setSnapshot(View.GONE);
            } else if(position == 1 && positionOffsetPixels == 0) {
                ((FragmentMap)adapter.getRegisteredFragment(1)).setSnapshot(View.VISIBLE);
            }
        }
        @Override
        public void onPageScrollStateChanged(int arg0) {}
        @Override
        public void onPageSelected(int arg0) {}
    });

My fragment with map (FragmentMap) is on position 1, so I need to controll the scroll from position 0 to 1 and from position 1 to 2 (the first if-clause). "getRegisteredFragment()" is a function in my custom FragmentPagerAdapter, in which I have a SparseArray(Fragment) called "registeredFragments".

So, whenever you scroll to or from your map, you always see a snapshot of it. This works very well for me.
