Common error message is "com.google.process.gapps stopped working" ,which renders the phone completely usless / totally annoying, as it appears each time I press the touchscreen. I got this error by tweaking / uninstalling stuff from phone to free some memory.
Then Google Play / Play Store refused to work with the error code RH-01 - error downloading from server
"eroare la recuperarea informatiilor de pe server rh-01"
"procesul com.google.process.gapps s-a oprit"
"Unfortunately, the process com.google.process.gapps has stopped"
"error retrieving information from server"
Been reading online about clearing cache/data about turning off and on download manager and google play, didn't fix shit for me.
Long story short, my solution was => Apparently Google uses Push Notifications to start thing up, I was in the wrongs by disabling "Hangouts" and "Google Messenger". After installing those 2 everything works now.
I will drop some links to the apk versions of both Hangouts and Messenger + Google Services and Play ( all updated to date March 1st, 2016) , simply download => Copy to SD card by usb cord and install.
Google Play Store 6.2.10.A
Google Play Services 8.7.02
Google Messenger 1.7.050
