Scenario:-

I have two ArrayList

list contains images

postList contains position of selected images

now when ever i am selecting the images and press delete menu ,it should delete the selected images .

when i am running the code in debug ,its working fine and give the desire output.

but when i am running it normal mode ,its crashing and giving above exception.

if (posList.size() > 0)
{
    Toast.makeText(getBaseContext(), "i value" +posList.size(), 
                   Toast.LENGTH_SHORT).show();
    for (int i = 0; i < posList.size(); i++)
        appAdp.list.remove(appAdp.list.get(posList.get(i)));
    appAdp.notifyDataSetChanged();
    posList.clear();
    Toast.makeText(getBaseContext(), "You deleted selected items",
                   Toast.LENGTH_SHORT).show();              
}
return true;

postList values here

@Override
        public void onItemCheckedStateChanged(ActionMode mode, int position, long id,
                boolean checked) {
            posList.add(position);

error showing here 

appAdp.list.remove(appAdp.list.get(posList.get(i)));

logcat:-

java.lang.IndexOutOfBoundsException: Invalid index 2, size is 2

at java.util.ArrayList.throwIndexOutOfBoundsException(ArrayList.java:251)

at java.util.ArrayList.get(ArrayList.java:304)

why its behaving like this ,not getting any clue.

Thanks for any help.
