I have an application which has a gridview with images in it. The problem is its showing in all phones except for API 21 i.e. Lollipop version. In Lollipop its shows just background and no gridview. The targetSDK is 21 and minSDK is 8. Any help in this would be much appreciated.

If you app has a values-21 folder in res folder, either set the layout there or delete the folder if you want persistent layout for all APIs.

in your adapter getView() method set the status of the clicked checkbox in model and call notify data set changed, try that
I added the following lines with my code and it started working fine:
ArrayList<Integer> checkedPositions = new ArrayList<Integer>();
final Integer index = new Integer(position);
holder1.chckbx1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (((CheckBox) v).isChecked()) {
// if checked, we add it to the list
checkedPositions.add(index);
} else if (checkedPositions.contains(index)) {
// else if remove it from the list (if it is present)
checkedPositions.remove(index);
}
}
});
// set the state of the checbox based on if it is checked or not.
holder1.chckbx1.setChecked(checkedPositions.contains(index));

It seems the values are not really being overwritten. Each time the second activity is loaded new part and type ArrayLists are being created. In these new lists only the latest part and type are added (in the onCreate Function) which have travelled with the intent.
If you want the list to keep adding the part and type selected by the user you can maintain the lists on the MainActivity. So upon selection of each item and type add it to the list on the MainActivity and then pass it to the ListViewItems activity.
This way the list will always have all the items selected by you.
I must admit I am not 100% sure if I understood your question correctly. But I have tried to answer with as much as I did.
EDIT:

Very old question, but no answer. I'm sure you have found a fix by now, but anyway.
You're changing the songs list object in background, and if Android decides to redraw your list (user scrolls your list), effectively accessing the songs list object, it may have changed and cause this exception to be thrown.
You need to use a temporary songs list and create a new adapter with it to update your list, thus not changing the current adapter list until you set a new adapter from the main UI thread.
