App not installed as package conflicts with an existing package

[j3soon]

When updating from v0.1 to v0.2 on my phone, the following error message occurs:

App not installed as package conflicts with an existing package.

The corresponding fix is to first uninstall v0.1 and then re-install v0.2, which will then require the user to re-configure the credentials/settings.

This will be an inconvenience if all future versions require an uninstallation before updating. I'll keep this open until a fix is confirmed.

As @ijsun mentioned, this issue may be caused by not updating the versionCode in commit bb2fed8.

@tigerpaws01, let's bump this number in the next release to see if it fixes the issue.

Aside from needing to update versionCode, the APK should also be signed by the same key to fully resolve this issue.

Since v0.2 is not signed, this issue can only be fixed in the next version (v0.4) based on the signed v0.3.
