I have almost a week figuring out how should I have one instance of exoplayer in background.
I want to use this instance in a playerview and in notification as well. Problem I am facing now, the player plays well, after a time it pauses (to release resource I guess), but when i click play it plays again, when i click other oudio, I get two audio playing at same time.
Here are my codes.

I don't take this as a best approach, but it gave me a quick solution while waiting for a better approach.
I will pot the app link here when it's available in playstore.
I have created an android application using the DJI SDK. I have followed the instruction, and basically copied the code from the DJI Sample Code (https://github.com/dji-sdk/Mobile-SDK-Android/blob/master/Sample%20Code/app/src/main/java/com/dji/sdk/sample/demo/camera/LiveStreamView.java), since it was working properly.
After launching a Connectivity activity, which registers the SDK and connects to the Mavic 2 Zoom drone, another activity comes, which handles live streaming to a RTMP server. When using the sample code, streaming to the same RTMP server, it has no delay, but when using my app, it has a good 15 second delay. I can't figure out why, I'm using the same components. The only difference is that I'm setting the camera focus to the max, but I did the same in the Sample Code, so it shouldn't cause any problems. Also using the same VideoFeedView as in the Sample.

Any idea why? I have tested it on Google Pixel 2, and Huawei Mate 10. The sample has no problem on both devices, my app has the delay. Thanks!
Answering my own question, the only difference I noticed was that the SampleCode asked for 4 permission, and all the projects I've tried or copied the permissions, always just 3 permissions.
So Manifest:
< uses-permission android:name="android.permission.RECORD_AUDIO" />
your runtime permissions:
Manifest.permission.RECORD_AUDIO
and the delay is gone, all works fine. Still don't know why :)

The buttons mBtnShuffle and mBtnRepeat do not trigger onCompletion. They are just 2 ordinary buttons that you use to set the flags isShuffle and isRepeat.
onCompletion is triggered when a song has been completed.
So if you want something to happen when the 2 buttons are tapped you should put some code in their listeners.
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 ?

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.
