i have 4 class A,B,C,D
From class A i goto Class B where all installed apps listed in listview. in Class B i send Packagelist to Class c (BaseAdapter class) and then which apps user have selected will pass to Class A.
So my problem is where or how can i use POJO class to pass installed Apps to baseadapter class and then how i can get all checked value(string app name) and pass it to the Class A. and also how i can maintain checked status of check box.
