I recently had difficulty syncronizing my contacts between Google and my Android tablet. The symptoms were actually pretty strange. I could change contacts, I could add them in Google and they would show up on my tablet. But, contacts created on the tablet would not only never make it to Google, but they wouldn’t even save on the tablet.
After some work and searching around, I found the solution was to reset the Android contact database.
WARNING!!!! YOU MUST DELETE YOUR CONTACTS FROM YOUR ANDROID TO RESET THE DATABASE. MAKE SURE TO BACK YOUR CONTACTS UP TO REMOVABLE STORAGE (SD Card) BEFORE BEGINNING THIS PROCESS!
After backing up your contacts to a removable storage device, follow this procedure:
From your main Android apps screen, click your menu button and select “settings”.
Click on “Accounts & sync” and uncheck “background sync”.
Return to your “settings” page (click the back key) and click “Applications”.
Select “Manage Applications” then choose “ALL”.
Find the “Contacts Storage” application and open it.
Click the “clear data” button.
Return to the main Android apps screen, click “menu” then select “settings” again.
Click on “Accounts & sync” and recheck “background sync”.
Then reload contacts from backup and select Google to syncronize with.
This resolved my issues, hopefully it may help someone else as well! Comments or questions? List them below!
