Well, when installing external APK, many of the games have in-app data downloader. One of them is battle cats which is the green bar download everytime after update.

Other games such as The World Ends With You, most online games like Brave Frontier, Summoner Wars, Valkrie Crusade, etc etc also have such thing.

However, some others like Chaos Rings III, SAS IV: Zombie Assault, Knights of Pen Paper, or Beast Breakers don't have it. So if you don't download and put the data along manually, the app just gonna force close or crash.
