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.
