checkbox issue in installed app in listview

I had refer these link , link , link , link
but my problem is not getting solved. i know there are many question
regarding this issue but my problem is
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.
any help plz. if code require then tell me.
