Camera starts in activities where its not needed

I have a QR code scanner in my app and the camera stops when my AlertDialog is being displayed but restarts as soon as I move to another activity and keeps running in the background even when the app isn't in the foreground.
I have the stopCamera() and stopCameraPreview() both but it restarts and stays on as long as the app is open (both foreground and background)
Here's the code for the activity:
public class MainActivity extends AppCompatActivity implements ZXingScannerView.ResultHandler {
private static final int REQUEST_CAMERA = 1;

} else {

}
}
}

}

"keeps running in the background even when the app isn't in the foreground" - this is due to the Activity lifecycle. Note that onDestroy() is the last method of the class Activity that is called and called only when activity is for sure destroyed.
What it means: when you move to the background onDestroy() is not called. The activity is still alive and waiting to be resumed. Your activity is still alive and it should be. Use instead of onDestroy() method called onPause(). You will reach this method if the activity is killed, and it will return back to the onResume() when appropriate.
Just overwrite onDestroy() to:
#Override
public void onPause() {
super.onPause();
scannerView.stopCamera();
scannerView.stopCameraPreview();
}

Text to Speech without button(will be continuous act)

this project code belongs to the project for the blinds to purchase the items. the scanresult fetch the details to the textview and reads for them and uses gesture options to handle the app.
i created the android project byr barcode scanner and output as textview and voice output. used xzing library as you can see it in the code. the problem is after showing the scanresult in plaintext, it does't atuostart the audio output functionallity. that is the real usage of this project. i referred youtube but can't. then making a chance to anyone to fix this program to text to voice.
this is my code, when working no errors at all. but no audio output after the scanresult from the barcodescanner. i tried my level best. so anyone can help out of it ??/?.

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.
