FirebaseDispatcher android sample

Hello, guys today we learn about what is FirebaseDispatcher and how to use our android project but before know about FirebaseRequestDispatcher, we know about JobScheduler.

What is JobScheduler?

The job scheduler is an android system service available on API level 21(Lollypop). It provides an  API for scheduling unit of work that will executed in your app process.

FirebaserequestDispatcher

The firebase jobDispatcher is a library for scheduling jobs in your android app. It provides a JobScheduler compatible API that works on all recent version of Android( API 14) that have google play service installed.


Dependency

 Add following line in your project build.gradle's dependencies section

implementation 'com.firebase:firebase-jobdispatcher:0.8.5'

How to use?

Simple extends with JobService class the JobService by default used Service class

import com.firebase.jobdispatcher.JobParameters;
import com.firebase.jobdispatcher.JobService;

public class MyJobService extends JobService {
    @Override
    public boolean onStartJob(JobParameters job) {
        // Do some work here
        return false; // Answers the question: "Is there still work going on?"
    }

    @Override
    public boolean onStopJob(JobParameters job) {
        return false; 
    }
}

Now create a simple dispatcher class and initialize google play driver

FirebaseJobDispatcher dispatcher =
    new FirebaseJobDispatcher(new GooglePlayDriver(context));

See source code 

MainActivity.java

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    private static final String JOB_TAG = "MyJobService";
    private FirebaseJobDispatcher mDispatcher;


    @Override    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        findViewById(R.id.btnstart).setOnClickListener(this);
        findViewById(R.id.btnstop).setOnClickListener(this);

        mDispatcher = new FirebaseJobDispatcher(new GooglePlayDriver(this));
    }

    @Override    public void onClick(View view) {
        int id = view.getId();
        if (R.id.btnstart == id) {
            scheduleJob();
        } else {
            cancelJob(JOB_TAG);
        }
    }


    private void scheduleJob() {
        Job myJob = mDispatcher.newJobBuilder()
                .setService(MyJobService.class) //  your job class name                .setTag(JOB_TAG) // define your tag name                .setRecurring(true)
                .setTrigger(Trigger.executionWindow(5, 60)) // trigger job every 1 min                .setLifetime(Lifetime.UNTIL_NEXT_BOOT)
                .setReplaceCurrent(false) // if you want when open your app then job auto replace with new job then this flag make true                .setConstraints(Constraint.ON_ANY_NETWORK)
                .setRetryStrategy(RetryStrategy.DEFAULT_LINEAR) // this is trigger linear time inteval like.. 1min,2min,3min,4min....                .build();
        mDispatcher.mustSchedule(myJob);
        Toast.makeText(this, "job_scheduled", Toast.LENGTH_LONG).show();
    }

    // cancel job    private void cancelJob(String jobTag) {
        if ("".equals(jobTag)) {
            mDispatcher.cancelAll();
        } else {
            mDispatcher.cancel(jobTag);
        }
        Toast.makeText(this, "job_cancelled", Toast.LENGTH_LONG).show();
    }
}

MyJobService.java

public class MyJobService extends JobService {
    private int ii = 0;
    private static final String TAG = "MyJobService";

    @Override    public boolean onStartJob(JobParameters jobParameters) {
        String currentDateTimeString = DateFormat.getDateTimeInstance().format(new Date());
        Log.e(TAG, "Job " + currentDateTimeString);
        sendNotification("DispatcherRequest","Current noti "+currentDateTimeString);
        return false;
    }

    @Override    public boolean onStopJob(JobParameters jobParameters) {
        Log.e(TAG, "Job cancelled!");
        return false;
    }


    private void sendNotification(String contentTitle, String message) {
        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        //notificationManager.cancelAll();

        Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);


        PendingIntent pendingIntent = PendingIntent.getActivity(this, 1 /* Request code */, intent,
                PendingIntent.FLAG_ONE_SHOT);

        String channelId = "default_notification_channel_id";
        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder =
                new NotificationCompat.Builder(this, channelId)
                        .setSmallIcon(R.mipmap.ic_launcher)
                        .setContentTitle(contentTitle)
                        .setContentText(message)
                        .setAutoCancel(true)
                        .setSound(defaultSoundUri)
                        .setContentIntent(pendingIntent);


        // Since android Oreo notification channel is needed.        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel channel = new NotificationChannel(channelId, "Channel human readable title",
                    NotificationManager.IMPORTANCE_DEFAULT);
            notificationManager.createNotificationChannel(channel);
        }

        notificationManager.notify(1 /* ID of notification */, notificationBuilder.build());
    }


}
