Android Packages Apps GmsCore Versions Save

This release fixes two major bugs introduced with v0.2.20.212158.

Notice regarding updates from v0.2.20.212158

If you already updated to v0.2.20.212158 and you can't install the update to v0.2.21.212158 the usual way, you may need to connect your device to a compute with adb installed and invoke the following commands in a shell:

adb push path/to/play-services-core-212158042.apk /data/local/tmp/play-services-core-212158042.apk
adb shell pm install-create -r --staged # This returns a session id in brackets
adb shell pm install-write *session-id* base /data/local/tmp/play-services-core-212158042.apk
adb shell pm install-commit *session-id*
adb shell rm /data/local/tmp/play-services-core-212158042.apk
adb reboot

If this doesn't work, you might need to directly update the .apk on your /system-partition or wait for the ROM developer to update to v0.2.21.212158.
