I have a ListFragment reading from a DB many records using AsyncTask.This fragment will need to be instantiated many times with different queries - basically I need multiple lists readily available.
I can't decide what is the best strategy for handling configuration change.
In their simplest implementation each strategy has side effects:
1) setRetainInstance seems not to keep the selected items/action mode when in CHOICE_MODE_MULTIPLE_MODAL
2) Saving Instance State will force me to reload the DB as the cursor is not persisted
3) As for retain a Model Fragment it would have to handle multiple instances of cursor
I will probably have to implement one of these anyway and work around the limitations, but i can't decide which one is the best option, any suggestion - or any other option?

I am writing a file to my external usb flash drive using the code in this stack overflow question. 
http://stackoverflow.com/questions/28228335/eacces-permission-denied-file-not-found
I am able to write the file but when I disconnect the flash drive keeping the device turned on 
and when I connect it back in and then try to write the file, I get a EACCES-permission-denied-file-not-found error. 
But if I do not disconnect the flash drive I am able to write to it multiple times without the error.

Still the same app as before, it has a single activity and several fragments - like your EU4YOU sample - but I've got a problem with the back button
If I start a fragment and then replace with a different one, when I press back the app disappears rather than going back to the previous fragment, I used the
beginTransaction()
.replace()
.addToBackStack()
.commit()
as in your example, but something else is missing I guess...

To get it to work I tried to implement onBackPressed() this way - found on S.O. - :
    @Override
    public void onBackPressed() {
        if (getFragmentManager().getBackStackEntryCount() > 0) {
            getFragmentManager().popBackStack();
        } else {
            this.finish();
