Should I use sync adapter

Question

My app requirement

Login.

Signup.

at 1 min periodic interval fetch data from server and update the UI.

no local db.

For Login and Signup I will use normal HTTP call but for periodic request at 1 min interval I was thinking to use SyncAdapter,

should I use SyncAdapter for this ?, even I have no local db storage.

Is it possible to update the UI from SyncAdapter ?

I have gone through the below links How do I use the Android SyncAdapter?

Answer 1

Sync adapters are designed to run at off times to keep data current between local and server. Not regularly, and certainly not every minute.

You should probably just implement a Timer, or Handler to control that.

Something similar to this answer.

private int mInterval = 60000; // 60 seconds
private Handler mHandler;

@Override
protected void onCreate(Bundle bundle) {
    ...
    mHandler = new Handler();
    startRepeatingTask();
}

Runnable mStatusChecker = new Runnable() {
    @Override 
    public void run() {
        downloadChangesFromServer();
        mHandler.postDelayed(mStatusChecker, mInterval);
    }
};

void startRepeatingTask() {
    mStatusChecker.run(); 
}

void stopRepeatingTask() {
    mHandler.removeCallbacks(mStatusChecker);
}
