How do I the data saved in local storage persist after updating the app?

Hi there.

I made a game for android that uses local storage to save the player's progress (saves and reads the data from an array), while I was testing and installing the debug apks, the data was kept correctly, no matter how many times the app is updated. But now that it is already in the play store, every time I upload an update (without modifying anything in the local storage) and it is installed, the data is not maintained.

Thanks for the help.

The data should be maintained if you update the app from the play store. But if you uninstall the app and then install a new version, the old data will be lost.
