Methods for periodic syncing in the SunshineSyncAdapter

SunshineSyncAdapter.java

    /**
     * Helper method to schedule the sync adapter periodic execution
     */
    public static void configurePeriodicSync(Context context, int syncInterval, int flexTime) {
        Account account = getSyncAccount(context);
        String authority = context.getString(R.string.content_authority);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            // we can enable inexact timers in our periodic sync
            SyncRequest request = new SyncRequest.Builder().
                    syncPeriodic(syncInterval, flexTime).
                    setSyncAdapter(account, authority).
                    setExtras(new Bundle()).build();
            ContentResolver.requestSync(request);
        } else {
            ContentResolver.addPeriodicSync(account,
                    authority, new Bundle(), syncInterval);
        }
    }


    private static void onAccountCreated(Account newAccount, Context context) {
        /*
         * Since we've created an account
         */
        SunshineSyncAdapter.configurePeriodicSync(context, SYNC_INTERVAL, SYNC_FLEXTIME);

        /*
         * Without calling setSyncAutomatically, our periodic sync will not be enabled.
         */
        ContentResolver.setSyncAutomatically(newAccount, context.getString(R.string.content_authority), true);

        /*
         * Finally, let's do a sync to get things started
         */
        syncImmediately(context);
    }

    public static void initializeSyncAdapter(Context context) {
        getSyncAccount(context);
    }

It is at the end of onCreate()

There's a problem in configurePeriodicSync() method to invokate SyncRequest() that is not public in android.content.SyncRequest().
