How to have a single instance of exoPlayer in a background?

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.

The link to the full code is : https://drive.google.com/open?id=1aQFcWHinIqqXHbTyssfPYTD20o9E2piA

In your onLoadFinished you assume mPictureURI is set and is not empty.
Now you have set a listener on mProductImageView for changes. No matter what you write/set down below the mProductImageView finally the in the listener it was set back to mPictureURI which was empty hence showing an empty image space.
Please have a look at the code below(also verified that it works).

Google Cloud Speech API for Android

Currently I`m working on a project where i have to use Google Cloud Speech Api and TextToSpeech. I try-ed to work around with RecognizerIntent but i would like to give a try to Cloud Speech .

Setting up Google Speech cloud on Android is not a straightforward 1,2,3 process, but I will give you some guidance.
Download the Sample project from here, use the Speech example.
https://github.com/GoogleCloudPlatform/android-docs-samples/tree/master/speech/Speech
Setup a google cloud project, enable the Speech API, and link it to
your gmail account's billing (you get 60min of free speech recognition
every month).
Generate an authentication json, and put it into the "raw" folder of
the sample project.
Setup Google cloud on your computer and obtain an access token.
Insert that access token on your SpeechService.java class.
*Documentation on steps 3 and 4:
https://cloud.google.com/speech/docs/getting-started
*If you run into problems when trying to mimic the sample project into your own project, check this:
Cannot import com.google.cloud.speech.v1.SpeechGrpc in Android
The exact steps are too long to list, I can't even remember them all, if you run into specific trouble let me know.

Android stop start_sticky service after finishing the task

and here is the NetworkUtil class in case u want to understand it more
public class NetworkUtil
{
public static final int NOT_CONNECTED = 0;
public static final int WIFI = 1;
public static final int MOBILE = 2;
public static int getConnectionStatus(Context context)
{
ConnectivityManager connectivityManager =
(ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
if(networkInfo != null)
{
if(networkInfo.getType() == ConnectivityManager.TYPE_WIFI)
{
return WIFI;
}
if(networkInfo.getType() == ConnectivityManager.TYPE_MOBILE)
{
return MOBILE;
}
}
return NOT_CONNECTED;
}
}

Somehow you can just register a BroadcastReceiver which shall get the intent for connectivity. No need to implement such logic.
Use below filters in your app Receiver:
<intent-filter>
<action android:name="android.net.wifi.WIFI_STATE_CHANGED"/>
<action android:name="android.net.wifi.STATE_CHANGE"/>
</intent-filter>
Follow the post below:
BroadcastReceiver when wifi or 3g network state changed
Hope it helps..

You can use an intent service to upload your data, which will be invoked from a dedicated network change broadcast receiver and probably even on click of a submit button as well.
The service will look something like:
public class UploadService extends IntentService {
#Override
protected void onHandleIntent(Intent workIntent) {
int networkState = NetworkUtil.getConnectionStatus(context);
DatabaseHandler db=new DatabaseHandler(context);
if(networkState == NetworkUtil.NOT_CONNECTED){
internetAvailable = false;
} else if(networkState == NetworkUtil.MOBILE){
internetAvailable = true;
//MainActivity.tvStatus.setText("ONLINE"); // you do something here.
} else if(networkState == NetworkUtil.WIFI){
internetAvailable = true;
if(db.getReportsCount()!=0){
reports=db.getAllReports();
for(Report report : reports){
Upload upload=new Upload(report);
Thread doInBackground = new Thread(upload);
doInBackground.start();
}
db.deleteAll();
}
}
}
public class Upload implements Runnable {
Report report;
public Upload(Report _report)
{
report=_report;
}
#Override
public void run() {
try {
MediaType MEDIA_TYPE_JPEG = MediaType.parse("image/jpeg");
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(30, TimeUnit.SECONDS)
.writeTimeout(120, TimeUnit.SECONDS)
.readTimeout(20, TimeUnit.SECONDS)
.build();
MultipartBody.Builder mRequestBody = new MultipartBody.Builder().setType(MultipartBody.FORM);
mRequestBody.addFormDataPart("category", report.getCategory());
mRequestBody.addFormDataPart("description", report.getDescription());
mRequestBody.addFormDataPart("city", report.getCity());
mRequestBody.addFormDataPart("address", report.getAddress());
mRequestBody.addFormDataPart("datetime", report.getDateTime());
mRequestBody.addFormDataPart("name", report.getName());
mRequestBody.addFormDataPart("email", report.getEmail());
mRequestBody.addFormDataPart("phone", report.getPhone());
if(report.getImages()[0].trim().length()!=0) {
ArrayList<Uri> fileUris = new ArrayList<>();
for (String uri : report.getImages())
{
fileUris.add(Uri.parse(uri));
}
for (Uri FileUri : fileUris)
{
File file = new File(FileUri.getPath());
RequestBody imageBody = RequestBody.create(MEDIA_TYPE_JPEG, file);
mRequestBody.addFormDataPart("images[]", FileUri.getLastPathSegment(), imageBody);
}
}
RequestBody requestBody = mRequestBody.build();
Request request = new Request.Builder()
