I have added below a screenshot I took of the app settings page. I want to know what the clear data and the force stop will do to my app?
Specifically, if my app has stored data into a file (I'm making a game and I want to store the progress) and the user presses any one of those buttons, especially clear data, I want to know if my file will be deleted and all the progress of the user in the game will be lost.
If I have stored my files in internal storage, will this happen? If so, should I use external storage? And what about SharedPreferences?
回答1:
on cleardata all internal data of the app will be lost,sharedprefrences,intenal files,database but the data saved on the external storage will remain.So i will advise you to store your data on external storage.
