Hello,
I'm trying to prepare an update to one of my apps and I just realized
that the updated version cannot read or write over the previous
version's SharedPreferences.
Some details:
* I'm using the 1.6 SDK and compiling for 1.5.3.
* My androidmanifest.xml does not have a sharedUserId (I didn't think
I need one if I was not sharing data between different apps).
How to reproduce:
* Install my current app from the market
* Run the app
* Exit and save the setting - invoking SharedPreferences Editor commit
(it's using MODE_PRIVATE)
* Now install my new update (via a browser download)
* Run the app
* Everything works fine
* Exit & Save
*** Now reboot the phone
* Run the app again
==> Can no longer access old data or write over it!!
Did I do something wrong? Is it because of the sharedUserId thing? Is
it because of the way I'm testing - via market then browser? Why is
LogCat reporting a UID change?
==> mismatched uid: 10031 on disk, 10046 in settings;
Can I recover from this? I don't want to delete all of my users' data.
help! =]
Here's some edited output from LogCat:
