I had the same problem when I updated to CM12 from CM11. A popup every few seconds telling me that Google Play has stopped. I tried flashing GApps multiple times, but to no avail.
I discovered that the cause of this is that the Google Play Store was installed, not as a system app, but as a user app. I speculate that this happened when installing CM12 over CM11, and not as a fresh install (wiping in recovery then installing).
The easiest way to determine if the app is installed as a user or system app, is to go into the app drawer and tap and hold on the app. If you can uninstall the app (by the Uninstall
text at the top of the screen. If you just see App info
, then it's a system app. Also please don't try and uninstall the app), then it is a user app.
I assume you're on the latest nightly and have the correct GApps installed.
To fix the problem, here's what I did:
Backup/Restore
tabConvert to system app
option. This should be at the bottom of the list under the SYSTEM ROM
titleIf you get a dialog or notification in Titanium Backup telling you "Not enough free space on system ROM." then you'll have to install CM12 as a clean install:
Wipe
, and slide the Swipe to Factory Reset
sliderInstall
Add More Zips
Swipe to Confirm Flash
sliderWipe cache/dalvik
, and swipe to clear the Cache and Dalvik Cache (optional: the Cache and Dalvik Cache should already be wiped by the recovery when you flash a new ROM. Wipe it if you really want to.)
