title: Android move app to sd
body: <p>Actually I want to find that what kind of items that are involved when we move the app to sd card? I have tried to search, but all the answer point me to "how to move app to sd" but actually I just want to know what items been move to sd and what items are left. I can see that there is still some memory left (in internal memory) when I move the app to sd. I am just curious what are the things left ? Where actually the app move to (in which part of the sd card)? </p>
