How to run shared obb files on Android

You may need to follow the following steps. The apps normally search for the additional files from the specific folders. If the application fails to find the specified folder, it may not run even if you have the obb files on your device, because the app will not search the entire memory.
1. If you have extracted the data folder, place it in Android/data.
2. Paste the obb files in Android/obb
3. Install the game and run it.
If your game does not run, or wants to download the files again - don't panic. You don't need to download them again. Let the app begin the download. Maybe it needs a specific folder for the data. Stop the download as soon as it begins, and using file manager- find the folders newly created by the app. Cut and Paste your data folder and obb files in the respective folders. Now run your game. It should run properly.

If your game is not running in spite of placing file in internal storage obb folder then there are chances your Leos Fortune game is asking for downloading additional data. But there is no need to download data again. You just need to verify your data. Some games need first time verification check to run on your device. Turn on your device internet and let the game verify your data.

For example, if you smartphone's internal memory is 512 MB and if you want to install a game of 1 GB, then you cannot install it without rooting your device. So in this case, obb file plays a very important role.
