Hi!I have to report, that the bug discussed here http://forums.arcgis.com/threads/46792-mapview.getMapDrawingCache%28%29-returns-null is only partly fixed for me. As said in that thread:The problem is that when the bitmap is the entire map there is a lag in generating the bitmap.
If the bitmap is a smaller area the lag is unnoticeable.
This a bug we are fixing.
The code posted earlier if executed twice works without a problem.
Try using the code below, if you single tap on the map twice you will see the bitmap.
map.setOnSingleTapListener(new OnSingleTapListener() {
/**
*
*/
private static final long serialVersionUID = 1L;
public void onSingleTap(float arg0, float arg1) {
Polygon polygon = map.getExtent();
Envelope env = new Envelope();
polygon.queryEnvelope(env);
Bitmap bitmap = map.getDrawingMapCache(arg0, arg1,
100, 100));
// Bitmap bitmap = map.getDrawingMapCache(0, 0,
// map.getWidth(), map.getHeight()));
Log.d(TAG, "width = " + map.getWidth() + " ht = "
+ map.getHeight());
ImageView img = new ImageView(HelloWorld.this);
img.setImageBitmap(bitmap);
map.addView(img);
}
});
Thanks

If you get the drawingcache from your whole mapview like this map.getDrawingMapCache(0f, 0f,mMapView.getWidth(), mMapView.getHeight()));
it becomes really unresponsive and simply unusable. If the area is smaller like for example 200x200 there is no noticeable drop in responsiveness. And sometimes I still need to call the method more then one time (but 2 times max).I have tested this with SDK v1.1, v1.1.1 and v2.0 on a Galaxy Tab 10.1n, Galaxy S 2.3.6 and a Galaxy Nexus with 4.1.1 with our ArcGIS Server 10.03. Unfortunately I can not provide any logs, because there are none for this bug.
