how to sync contacts automatically on adding an account?

Question

I have built an account and the sync works fine . But the problem is I have to explicitly check the sync contacts checkbox to trigger the sync adapter. Is there any way to automate it and have it checked automatically on account adding?

Answer 1

After some research with stachoverflow and android docs, The below code does the Trick

ContentResolver.setSyncAutomatically(account, ContactsContract.AUTHORITY, true);

Tested on android version ics and above.

Answer 2

To sync automatically use:

ContentResolver.setSyncAutomatically(account, ContactsContract.AUTHORITY, true);

To sync periodically use:

ContentResolver.addPeriodicSync(account, ContactsContract.AUTHORITY, Bundle.EMPTY, SYNC_INTERVAL_IN_SECONDS);

Following documentation demonstrating different ways of running the sync: Running a Sync Adapter
