Learn about Firebase Job Dispatcher using this step by step example.

Step 1: Create Project

Start by creating an empty Android Studio project.

Step 2: Dependencies

Declare firebase-jobdispatcher as a dependency in your app/build.gradle file:

    implementation "com.firebase:firebase-jobdispatcher:$firebaseJobDispatcherVer"

Step 4: Create a Job Service


import com.firebase.jobdispatcher.JobParameters
import com.firebase.jobdispatcher.JobService
import java.util.logging.Logger

class MyJobService : JobService() {

    companion object {
        val log = Logger.getLogger(MyJobService::class.java.name)

    override fun onStopJob(job: JobParameters?): Boolean {
        log.info("Stopped Job")
        return false

    override fun onStartJob(job: JobParameters?): Boolean {
        log.info("Started Job")
        return false


Step 5: Register the Service

Register the Job service in the AndroidMainifest.xml as shown:

                <action android:name="com.firebase.jobdispatcher.ACTION_EXECUTE" />

Step 6: Create MainActivity

Create your main activity as below:


import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import com.firebase.jobdispatcher.FirebaseJobDispatcher
import com.firebase.jobdispatcher.GooglePlayDriver
import com.firebase.jobdispatcher.Trigger

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        val dispatcher = FirebaseJobDispatcher(GooglePlayDriver(this))
        val job = dispatcher.newJobBuilder()
                //x is know as windowStart, which is the earliest time (in seconds) the job should
                // be considered eligible to run. Calculated from when the job was scheduled (for new jobs)
                //y is known as windowEnd,
                // The latest time (in seconds) the job should be run in an ideal world. Calculated in the same way as windowStart.
                .setTrigger(Trigger.executionWindow(0, 60))
