Launcher activity onResume () method is called twice, but onCreate () only once

Question

When my application starts, the onCreate () start function usually runs only once. But this is immediately followed by two calls to onResume (). When I check the code, both instances of the same class, but only one of them has instances from onCreate (), obviously.

Everything is working fine. I'm just curious to know why this is happening. Does anyone have any ideas? I use SherlockFragmentActivity, does this have anything to do with this? I am pleased to provide additional information as necessary. I just don’t know what else is needed.

Thanks!
