Hello there. I am using agis sdk 10.2.2 with Android API 19.
I add a MapView to MainActiviety it works.
When I add a Blank MapView to Fragment it works too,.
But when I Add a Layer to MapView of Fragment, App crashed.

Does anyone has an example to show how to add MapView to Fragment ?
Thanks.

I know what happened�?��?�

Just
mMapView = (MapView)findViewById(R.id.map);
when Fragment unload, so mMapView is null and
java.lang.NullPointerException.

What a foolish mistake�?�
