[Interest] [Android] Preserve data files after deployment

[Ben Lau]

Hi all,

I found that every time deploying an application through Qt creator to
Android device will erase the previous created data file.

For example , my application stores the user preference using SQLite. It is
saved in the HomeLocation ( /data/data/${package}/files ) . When a new
version is deployed via Qt creator , the path and all the data will be
erased and therefore the user preference will be lost.

It is very annoying. Is there any method which can preserve the data file
after deployment?

Thanks.
