Question

Problem with checkbox in installed application in listview

I referred to these links link , link , link , link

but my problem is not resolved. I know there are many questions regarding this problem, but my problem

I have grade 4 A, B, C, D

From class A, I goto class B, where all installed applications are listed. in class B, send Packagelist to class c (BaseAdapter class) and then the user who selected the user will go to class A.

So my problem is where and how can I use the POJO class to transfer installed applications to the baseadapter class, and then how can I get all the checked value (application string name) and pass it to class A. as well as how I can support checked flag status.

any help plz.
