I have implemented a sync adapter in my app which requires an account to be added in the device account settings. I followed the same approach given in the Android docs. It works fine till Marshmallow and I can see my account listed in the device accounts. But in Android N preview, account does not add to the device accounts. AccountManager's addAccountExplicitly() method always returns false. Has anyone faced this problem?
Not sure if this is the same issue, but there's an issue with AccountManager on the current version of the Android N image. Basically, if you:
- Add an account to AccountManager
- Uninstall the app
- Reinstall the app
- Try to add account again
This will fail and you'll see the following in the log:
W/AccountManagerService( 1503): insertAccountIntoDatabase: Account {name=foo@bar.com, type=com.foo.bar}, skipping since the account already exists
This is a known issue and it's been reported to Google: https://code.google.com/p/android/issues/detail?id=210992 https://code.google.com/p/android/issues/detail?id=210951
I have totally the same issue.
I could fix it by manually going to the application settings and enabling Сontacts permission. I don't know how, but after that I was able to use addAccountExplicitly() method without issues. I even disabled that permission again and cleared app data but it still was working properly...
After app was reinstalled - problem appeared again.
Has this been fixed now in the latest Android N release.
