Does Service needs another parser?

Does Service needs another parser? - java

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.

Scanning for bluetooth devices programmatically don't find anything in android 6+

I created an application which pairs a cellphone to a bluetooth module.
i tested this application with a 4.2 android cellphone and it worked quite well but in cellphones with android higher than 6 the device is not fidning anything when i press " Scan for new devices " button.
but when i go through my phone bluetooth itself, i can find the module i was looking for..

in an article i studied about this issue and find out that with this code :
if (ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_COARSE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(context,
new String[]{Manifest.permission.ACCESS_COARSE_LOCATION},
1);
i can make the application to support phones with android more than 6 so i can discover all nearby devices and pair with them,
The issue is, i don't know where should i exactly use this code..
i would really appreciate if you could tell me where to use it within the codes i showed here.
or simply tell me how to overcome this problem with any other code you may know.

In your AndroidManifest.xml file add this:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
Then, instead of calling registerReceiver call this function:
private tryRegisterReceiver() {
if (ContextCompat.checkSelfPermission(thisActivity,
Manifest.permission.ACCESS_COARSE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
// Here, permission is not granted
// after calling requestPermissions, the result must be treated in onRequestPermissionResult
ActivityCompat.requestPermissions(thisActivity,
new String[]{Manifest.permission.ACCESS_COARSE_LOCATION},
1000); // 100 or other desired code
} else {
// Permission has already been granted
// continue registering your receiver
registerReceiver();
}
}

splash screen getting value from the service

I have splash screen which has count down time. I am assigning time value manually in my example time = 10000.
1)How can I assign value which I am getting from the service to the time variable.
2) How can I compare both the time and then assign the service time to the splash screen activity.

If RecyclerView scrolls, then item id changes. How to resolve this?

This is my PDFListAdapter class method. I have downloaded file locally and save on Sqlite database. But if I scroll my RecyclerView, then I am having different item id. If not scroll RecyclerView then item id is perfect.
The problem is when I scroll down the RecyclerView the item id changes. That is, I can fit one item on the screen at once. When I scroll to the second item, it saves different file and opens different.

I have modified your onBindViewHolder function. The changes are following.
Declared the pdfList variable as final and used it everywhere. It is not necessary to get the pdfList from the pdfModelClasses, each time you use it.
The holder variable is removed, as it is not actually necessary. The holder1 is used everywhere.
There are some changes with the visibility of the buttons. Check holder1.imgDownloadNote.setOnClickListener.
I have found no other problem in your onBindViewHolder. Please let me know if the modified code works.

Manage some flag and pass information from notification to MainActivity via Intent.
use switch case or if/else in your MainActivity, if you are receiving perticular flag/data, load desired fragment.
Intent passIntent = new Intent(this, MainActivity.class);
passIntent.putExtra("flag","some value");
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, passIntent, 0);
in your MainActivity.java
if(getIntent().hasExtra("flag")){
if(getIntent.getStringExtra("flag").equalsIgnorCase("some value"))
{
//write code to load your fragment.
}
}

Video and audio call 2 Android devices - webrtc

I'm trying do develop Android app which will send audio and video via webrtc protocol between devices. This code works well with Android and web interface, but not between two Androids. Every time connection is opened and popup says that devices are connected, but there is no sound and picture. I tried a lot of things, but nothing helped. Dependencies and permissions are ok. Used my own pub and sub keys from PubNub. It opens connection 1 of 20 times between two Androids, so I think that something isn't working well here.
Followed this tutorial to create app: tutorial
I found this error image

I will appreciate any help. Thanks to everybody.

when You run your application that time they ask sign in usename
that time you wrote your name
put that name in VideoChatActivity class
this.pnRTCClient.listenOn("your name when your wrote at signin time");
this.pnRTCClient.setMaxConnections(3);
