How to empty a gridview on Android?

Question

I am developping a launcher with two different profiles : one is the main one the other is secondary. If I go on the play store and then come back with the "back" button, I land on my main profile, but there, the icons of my gridview (displayed through an adapter) appear in double (if I install two apps from the play store, coming back with the back button will give me icons 3 times and so on).

If I restart my main activity in the onresume method, things go fine and my icons aren't doubled, or tripled or whaterver. But I don't want to restart the activity, I only want to empty my gridview.

if((admin == true) ){
        Intent intent = getIntent();
        finish();
        startActivity(intent);}

I had the same problem myself. The easiest way to do this is:

gridview.setAdapter(null);
