Volley POST to send multiple JSON

I have a problem with a volley to send multiple JSON with StringRequest, I think the problem is in the hashmap un getParms()

The problem is when I get the data to send, in the for the JSON for send are ok, but in the getparms() this only set the last JSON for send, and send many times of the total array

Does Service needs another parser?

I have already been fetched data from instagram api. But i cannot reach that data to use it on my service. I have tried all methods that i know.
**Here is my main object: ** If my followers count is increases or decreases, notify, And check that for every 5 min.(I am still working on it. There are lots of misses yet.)
**Here is my main question: ** Do i really have to create a new parser to fetch data that i already have or what should i build?
If you have any sample or Articles for this case, that would be useful.
I heard about Csv file. Is that can be useful to import ?
PS: I learned java and android studio yet. I am pretty newbie.

The only solution that i found is the adding parser to your service to reach data from api. None of the the method can access to reach data from service to activity.
I added this class to reach api data on service.
public void lilParser() throws IOException, JSONException{
URL url = new URL(API_URL + "/users/" + mSession.getId()
+ "/?access_token=" + mAccessToken);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.setDoInput(true);
urlConnection.connect();
String response = Utils.streamToString(urlConnection
.getInputStream());
System.out.println(response);
JSONObject jsonObj = (JSONObject) new JSONTokener(response).nextValue();
JSONObject data_obj = jsonObj.getJSONObject("data");
JSONObject counts_obj = data_obj.getJSONObject("counts");
String name = jsonObj.getJSONObject("data").getString("full_name");
String bio =jsonObj.getJSONObject("data").getString("bio");
String counts=jsonObj.getJSONObject("data").getString("counts");
userInfoHashmap.put(TAG_FOLLOWED_BY,counts_obj.getString(TAG_FOLLOWED_BY));
Log.i(TAG,"followedby=>[" + counts + "]");
}
And, Here is my onCreate. You can check The data if it is changed or not.
#Override
public void onCreate() {
Toast.makeText(this,"Service Started", Toast.LENGTH_LONG).show();
myTimer = new Timer();
myTimer.schedule(new TimerTask() {
#Override
public void run() {
String fo = userInfoHashmap.get(TAG_FOLLOWED_BY);
try {
lilParser();
}
catch (IOException e) {e.printStackTrace();}
catch (JSONException e) {e.printStackTrace();}
if(new String(userInfoHashmap.get(TAG_FOLLOWED_BY)).equals(fo)==true){}
else {
getnotification();
}
}
}, 0, 30000);
}
PS: I published my code, that may help someone else. I am still newbie.

This issue is due to variable not being instantiated. You are using the activity as a Context too early. You need to wait until onCreate() or later in the activity lifecycle. You can't call getApplicationContext() until after onCreate() is called. The Activity is not fully initialized until then.

How to validate the Nymi band Asynchronously?

I am trying to validate the Nymi band asynchronously . But when I try to do that, I get the following exception:
java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()
I have all the toasts in the following method as you can see:
runOnUiThread(new Runnable() {
#Override
public void run() {
Toast.makeText(TestBluetooth.this, "Failed to initialize NCL library!", Toast.LENGTH_LONG).show();
}
});
But Still I get the exception. The method works fine when run normally in the onCreate() method,but fails to run asynchronously .
Edit: Even after removing all the toasts, I still get the exception.
Here is my Thread class,where I am calling the validate() asynchronously :
public class NymiAsync extends AsyncTask<Integer,Integer,Integer> {
#Override
protected Integer doInBackground(Integer... integers) {
try{
TestBluetooth tb=new TestBluetooth();
tb.startValidatingNymi();
}catch (Exception e){
e.printStackTrace();
}
return 0;
}
}
Here is the main class where I have the validate methods:

Edit: After I made the NYmiAssync as inner class, I am able to run the it async using the following :
new Thread() {
public void run() {
TestBluetooth.this.runOnUiThread(new Runnable(){
#Override
public void run() {
try {
NymiAsync task = new NymiAsync();
task.execute(1, 1, 1);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
}.start();
But, I have no idea, how to make it run for every 10 seconds.

The problem is in the asynctask:
public class NymiAsync extends AsyncTask<Integer,Integer,Integer> {
#Override
protected Integer doInBackground(Integer... integers) {
try{
TestBluetooth tb=new TestBluetooth();
tb.startValidatingNymi();
}catch (Exception e){
e.printStackTrace();
}
return 0;
}
}
Just make the class an inner class of TestBluetooth and then just call startValidatingNymi()
public class NymiAsync extends AsyncTask<Integer,Integer,Integer> {
#Override
protected Integer doInBackground(Integer... integers) {
try{
startValidatingNymi();
}catch (Exception e){
e.printStackTrace();
}
return 0;
}
}

that is because the code below in TestBlutooth:
final Handler timedThread=new Handler();
but in doInBackground you create a instance of TestBluetooth, so you get the exception
