As we know, most of the games general  tmp and persistent data on running. My question is that it's quite easy to mistakenly delete those data when managing the device with apps such as AirDroid. Is there any way to recover game data in such case? or just store the data on cloud?

 

Did you try some Android data recovery programs? maybe it works for you, but I should remind you that stop using your Android phone in case the "deleted data" was covered by new data, if that's the truth, you will lost your data forever.

Yes, you should do regular backups, any accidents can result in data loss.

I think you can have a try of data recovery programs, I have tried that before, you can easily recover contacts, texts. oh, the premise is that you did add more data to your phone.
