CM11 Kindle Fire - "Incompatible with other applications(s) using the same shared user ID" with Google Calendar I'm running Cyanogenmod 11 (KitKat 4.4.4) on my 1st Gen (Otter) Kindle Fire, with GApps installed.

I can install other apps just fine, I installed Slack with no issues. However, when I went to install Google Calendar, I got this error:

Incompatible with other applications(s) using the same shared user ID


I've been looking through forums and I haven't found anything that has fixed it. I've tried a fresh GApps installation, wiping the cache, reinstalling the ROM, nothing has worked. I tried to look into the files and could not find a packages.xml file, so I cannot take out the line of code I've seen mentioned that could be causing issues.

I'm seriously stumped by this and would love any input!
In order to solve this, I had to install the APK file myself for Google Calendar after downloading it and allowing my device to accept 3rd party apps. Since then I've had no issues!
