어플 목록 불러와서 삭제버튼을 통해 삭제해야되는데 삭제버튼이 안되요..도와주세요 ㅜㅜ

Question

어플 목록을 불러와서 삭제해주는 어플을 구현중인데요... 잘안되요 ㅠㅠㅠ

버튼을 누르면 삭제가 되야하는데 안되네요,,ㅠㅠㅠ 

버튼이 각각의 어플 패키지명을 받아야하는데 못받는거같아요..

도와주세요 ㅜㅜ

 

그리고 혹시.. 어플 실행했던 마지막 시간을 받아오는 방법은 없나요.,,? 좀 알려주세요 ㅠㅠ
 
이 부분과

         Uri packageURI = Uri.fromParts("package", (String) v.getTag() , null);//이부분이문제인듯한데요.....ㅜㅜㅜ
            Intent uninstallIntent = new Intent(Intent.ACTION_DELETE, packageURI);
            uninstallIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

..

이쪽 부분이 문제인듯 싶은데요,,
        addInfo.mAppPackge = app.packageName;
        btn.setTag(app.packageName);  //이렇게하는거아닌가요...;;
        mListData.add(addInfo);
도와주세요 고수님들 ㅠㅠ
