Android, APK returning to previous version after reboot

Question

I'm writing a software for a customer; that software will be pre-installed onto a custom ROM.

One of the features of that software is update it-self to a newer version when available.

Everything works well, but the problem is this; when the device is rebooted or restarted, the updated version disappears! The old version returns.

There is something different to be write to create pre-installed software that can be updated?

Thank you in advance for any guidance/suggestions.

Answer 1

I finally fixed the problem. So stupid by the way :) Because I was not updating the APK using Google Play, I was not changing the VERSIONCODE in Manifest! Just that. Everything else was ok. So, if someone else has the same problem, this is my tip: always change the versionCode and versionName.

Thank you for your help!
