Android JobScheduler Sample

This sample has been deprecated/archived meaning it's read-only and it's no longer actively maintained (more details on archiving can be found here).

Instead of JobScheduler, we recommend using the WorkManager. For a sample in that (and other related samples), check out the new github.com/android/background-tasks-samples repo. Thank you!

android-jobscheduler's Issues

Can JobScheduler run on API level 18 or minimum API 21 is required?

Cancelling schedule was not working

Steps to Reproduce

1. Set the work duration for 10 seconds
2. Click schedule job.
3. click finish last task button at 3 seconds. onstop task event will get triggered.
4. At 10th second also on stop task button will glow.
   This is because of calling sendMessage method within the run method of myjobservice class

after Android O background services cannot be started?

I'm not sure this example has been updated for Android O and beyond. How do you anticipate avoiding the following kind of exception?

gradlew build failed

1. I execute gradlew build in root directory，got the following error message:

2. If I load project in android studio, after update, sync ..., also failed.

Periodic job not working

When I remove my app from the currently running apps list, then my job service does not show in adb shell dumpsys jobscheduler and it stops working periodically.

IDE project files checked in repo

1. it is bad practices to check in your ide related files
2. since you are using gradle, project can be easily recovered from build.gradle files.

when the reboot the system all the jobs are closed

After adding the jobs in job scheduler and reboot the system and open the app all pending jobs are cancelled. why?

typo in Class description of Log.java

Most of the methods in this class server only to map a method call in Log to its equivalent in LogNode.

IMO, server should actually be serve.

JobScheduler start job not triggered.

Hi I have been using JobScheduler since 3months. Haven't faced any issue until yesterday. It seem there is a behaviour change in the way it works. Whenever i use jobscheduler.schedule(jobinfo) it used to trigger immediately but right now it take 5mins or more to trigger the Job Service. Can I know why is this happening?

jobInfo = new JobInfo.Builder(JOB_SERVICE_LOCATION_PROBE, new ComponentName(getApplicationContext(), LocationJob.class))
                                        .setBackoffCriteria(BACKGROUND_JOB_BACK_OFF, JobInfo.BACKOFF_POLICY_EXPONENTIAL)
                                        .setRequiredNetworkType(JobInfo.NETWORK_TYPE_ANY)
                                        .setExtras(persistableBundle).build();

jobscheduler.schedule(jobInfo);

The 'onStartJob' method return a wrong result

In this sample, there are lines of code as below

    @Override
    public boolean onStartJob(JobParameters params) {
        // We don't do any real 'work' in this sample app. All we'll
        // do is track which jobs have landed on our service, and
        // update the UI accordingly.
        jobParamsMap.add(params);
        if (mActivity != null) {
            mActivity.onReceivedStartJob(params);
        }
        Log.i(TAG, "on start job: " + params.getJobId());
        return true;
    }

and return 'true' or return 'false' is based on the below words

True if your service needs to process the work (on a separate thread). False if
there's no more work to be done for this job.

In the 'onStartJob' you return 'true' and the sample does not process any time-wasted work, so I think you should return false here.

Start and stop job scheduling

I want to start and end scheduling through start and stop buttons. Once the scheduling works in the background, how can I stop it and vice versa? I didn't find the way to stop scheduler anywhere. cancelAll() only cancels the pending jobs but the scheduler does works again.

Main class

public class LiveTrack extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_live_track);

        //start scheduling
        startLiveTrackBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                jobScheduler = (JobScheduler)getSystemService(JOB_SCHEDULER_SERVICE);
                ComponentName jobService =
                                new ComponentName(getPackageName(), MyJobService.class.getName());
                JobInfo jobInfo =
                                new JobInfo.Builder(MYJOBID, jobService)
                                        .setPeriodic(15 * 60 * 1000L)
                                        .setExtras(bundle)
                                        .build();
                int jobId = jobScheduler.schedule(jobInfo);

                if(jobScheduler.schedule(jobInfo)>0){
                }else{
                    Log.e("status","failed");
                }
            }
        }

        //stop scheduling
        endLiveTrackBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //how can I stop scheduling here until the start button is clicked again??  
                jobScheduler.cancelAll();
            }
        });
    }
}

JobService class

public class MyJobService extends JobService{
    @Override
    public boolean onStartJob(JobParameters jobParameters) {
        //some work
    }

    @Override
    public boolean onStopJob(JobParameters jobParameters) {
    }
}
