onPostExecute() seems to be called only once - android

I've created class which extends AsyncTask, to synchronize with service. After synchro is finished I want to put the time (hh:mm) into TextView, to inform user, when synchro was made last time. I am doing it inside onPostExecute().
Problem is that this happens only once. TextView doesn't get updated later.
I'm prettey sure doInBackground() is being called because it takes quite a long time to synchronize just like when application starts (there is a lot of records), but I can't be 100% sure since data collection doesn't change at all.
That's my AsyncTask class:
private class Reconnect extends AsyncTask<String, Void, Void>{
private RotateAnimation anim = new RotateAnimation(0f, 360f, Animation.RELATIVE_TO_SELF,0.5f, Animation.RELATIVE_TO_SELF,0.5f);
#Override
protected void onPreExecute() {
rlRefresh.setEnabled(false);
anim.setInterpolator(new LinearInterpolator());
anim.setRepeatCount(Animation.INFINITE);
anim.setDuration(700);
refreshIV.startAnimation(anim);
}
#Override
protected Void doInBackground(String... strings) {
retrofit2.Call<List<ServiceTaskAxapta>> call = api.getTasks("1", strings[0]);
retrofit2.Response<List<ServiceTaskAxapta>> response = null;
try {
response = call.execute();
} catch (IOException e) {
e.printStackTrace();
}
if(response.code() != 200){
Toast.makeText(context, "Error 1", Toast.LENGTH_SHORT).show();
} else {

String lastSynchro = calendar.get(Calendar.HOUR_OF_DAY) + ":" + calendar.get(Calendar.MINUTE) + "#" + calendar.get(Calendar.DAY_OF_MONTH) + "-" + (calendar.get(Calendar.MONTH)-1) + "-" + calendar.get(Calendar.YEAR);
ProjectStuff.saveLastSynchro(lastSynchro, context);
String synchroTime = "Last synchro: " + DateParser.parseTime(context, calendar.get(Calendar.HOUR_OF_DAY), calendar.get(Calendar.MINUTE));
tvSynchroInfo.setText(synchroTime);
rlRefresh.setEnabled(true);
}
}
And the execute() method:
rlRefresh.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Reconnect refreshEvent = new Reconnect();
refreshEvent.execute("12");
}
});
After amount of time (needed to synchronize), amination stops, so it looks like onPostExecute() is called, and TextView is updated, but every later call doesn't update it.


Ok, I've found the problem. I called calendar = Calendar.getInstance() inside onCreate() method, I should have done this in onPostExecute() right before saving it, and showing it inside TextView to get right time.

Can someone show me how I can pause my code until an onDataChange() Value event listener has completed?

Can someone please show me how I can pause my code in onCreate() until the event listener getting data from my firebase realtime DB has completed?
I have been stuck on this for a while now, anything that does not involve me completely reformatting my code would be awesome.
My code works but when getting data from the firebase my code continues to run without waiting for the EventListener to recieve the data...
I need to be able to stop the code but I do not know how...
-Just a suggestion: is it possible to use Thread.wait() and Thread.notify()?
I don't understand how threads/tasks/runnables work that well so a good explanation would be appreciated.

Access to google calendar events

I want to get the events from a public google calendar in my app.
This is my activity, with the access to somePublicCalendar#google.com which I've changed for a fake account, but my calendar is public. Of course, somePublicCalendar#gmail.com is not my account and I can't manage it. Just want to see if I there's a gap for scheduling and appointment.

Get Cached data storage programmatically

I want to get cached data size at "Internal storage" in "settings", like this:
I tried to get all application cache by invoking getPackageSizeInfo using Java Reflection. Yes it did got all cached size of apps, but the size is smaller than the cached data size in "settings" above. This is the picture when I used this method:
in settings, the cached data size 840 MB, but when in my app is 493 MB.
These are my codes

How to update the Recylerview View items after displayed First Json URL In android

I having a problem update the Item in Recycler View.I will explain clearly about my problem.
I am using two Json URL's first Json URL can send the items to model class.
after completed this called the adapter, then update the second Json URL items with the adapter by using setter model class.
so that's why called adapter.notifyitemchanged, but only one time can updated items next time while looping doesn't update the items display empty for second time.
Code:
public void servicecallsingle(String list, final int pin) {
url = Constants.singleproducturl + list;
JsonObjectRequest request1 = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener < JSONObject > () {
#Override

JSONObject response1 = response;
if (response1 != null) {
// int status=jsonObject.optInt("status");
String status = response1.optString("status");
if (status.equalsIgnoreCase("200")) { //check the status 200 or not

Anyone solve this problem glad to appreciate.
Thanks in advance

The problem is volley doesn't wait for the request to be completed. So as the first call is made within seconds other call will be also made. So, you need to create an interface which will be called when the first webservice is called, and than in interface call other webservice and than notifyDataSet.
