Android how to enable/disable auto sync programmatically

Question

I need to know how to toggle auto sync on and off programmatically.

Answer 1

I think you are looking for

ContentResolver.setMasterSyncAutomatically(<boolean>);

What docs says:

Sets the master auto-sync setting that applies to all the providers and accounts. If this is false then the per-provider auto-sync setting is ignored.

This method requires the caller to hold the permission WRITE_SYNC_SETTINGS.

So don't forget to add permission into manifest.xml:

<uses-permission android:name="android.permission.WRITE_SYNC_SETTINGS" />

This should disable / enable all the syncs.

Code for Sync Accounts Programmatically:

Sync once:

public static void syncAllAccounts(Context contextAct) throws Exception {
    AccountManager manager = AccountManager.get(contextAct);
    Account[] accounts = manager.getAccountsByType("com.google");
    String accountName = "";
    String accountType = "";
    for (Account account : accounts) {
        accountName = account.name;
        accountType = account.type;
        break;
    }

    Account a = new Account(accountName, accountType);
    ContentResolver.requestSync(a, "com.android.calendar", new Bundle());
}

Sync on time interval automatically:

public static void syncAllAccountsPeriodically(Context contextAct, long seconds) throws Exception {
    AccountManager manager = AccountManager.get(contextAct);
    Account[] accounts = manager.getAccountsByType("com.google");
    String accountName = "";
    String accountType = "";
    for (Account account : accounts) {
        accountName = account.name;
        accountType = account.type;
        break;
    }

    Account a = new Account(accountName, accountType);
    ContentResolver.addPeriodicSync(a, "com.android.calendar", new Bundle(), seconds*1000);
}

If you want to sync accounts once, call first method and if you want to sync on some time of interval you have to call second method and pass seconds (Like 10 Seconds) as arguments in it.
