JobParameters

STOP_REASON_APP_STANDBY

public static final int STOP_REASON_APP_STANDBY

The current standby bucket requires that the job stop now.

Constant Value: 12 (0x0000000c)

STOP_REASON_BACKGROUND_RESTRICTION

public static final int STOP_REASON_BACKGROUND_RESTRICTION

The app is restricted from running in the background.

Constant Value: 11 (0x0000000b)

STOP_REASON_CANCELLED_BY_APP

public static final int STOP_REASON_CANCELLED_BY_APP

The job was cancelled directly by the app, either by calling JobScheduler.cancel(int), JobScheduler.cancelAll(), or by scheduling a new job with the same job ID.

Constant Value: 1 (0x00000001)

STOP_REASON_CONSTRAINT_BATTERY_NOT_LOW

public static final int STOP_REASON_CONSTRAINT_BATTERY_NOT_LOW

The requested battery-not-low constraint is no longer satisfied.

Constant Value: 5 (0x00000005)

STOP_REASON_CONSTRAINT_CHARGING

public static final int STOP_REASON_CONSTRAINT_CHARGING

The requested charging constraint is no longer satisfied.

Constant Value: 6 (0x00000006)

STOP_REASON_CONSTRAINT_CONNECTIVITY

public static final int STOP_REASON_CONSTRAINT_CONNECTIVITY

The requested connectivity constraint is no longer satisfied.

Constant Value: 7 (0x00000007)

STOP_REASON_CONSTRAINT_DEVICE_IDLE

public static final int STOP_REASON_CONSTRAINT_DEVICE_IDLE

The requested idle constraint is no longer satisfied.

Constant Value: 8 (0x00000008)

STOP_REASON_CONSTRAINT_STORAGE_NOT_LOW

public static final int STOP_REASON_CONSTRAINT_STORAGE_NOT_LOW

The requested storage-not-low constraint is no longer satisfied.

Constant Value: 9 (0x00000009)

STOP_REASON_DEVICE_STATE

public static final int STOP_REASON_DEVICE_STATE

The device state (eg. Doze, battery saver, memory usage, etc) requires JobScheduler stop this job.

Constant Value: 4 (0x00000004)

STOP_REASON_ESTIMATED_APP_LAUNCH_TIME_CHANGED

public static final int STOP_REASON_ESTIMATED_APP_LAUNCH_TIME_CHANGED

The system's estimate of when the app will be launched changed significantly enough to decide this job shouldn't be running right now. This will mostly apply to prefetch jobs.

Constant Value: 15 (0x0000000f)

STOP_REASON_PREEMPT

public static final int STOP_REASON_PREEMPT

The job was stopped to run a higher priority job of the app.

Constant Value: 2 (0x00000002)

STOP_REASON_QUOTA

public static final int STOP_REASON_QUOTA

The app has consumed all of its current quota. Each app is assigned a quota of how much it can run jobs within a certain time frame. The quota is informed, in part, by app standby buckets. Once an app has used up all of its quota, it won't be able to start jobs until quota is replenished, is changed, or is temporarily not applied.

Constant Value: 10 (0x0000000a)

Constant Value: 14 (0x0000000e)

STOP_REASON_TIMEOUT

public static final int STOP_REASON_TIMEOUT

The job used up its maximum execution time and timed out. Each individual job has a maximum execution time limit, regardless of how much total quota the app has. See the note on JobScheduler and JobInfo for the execution time limits.

Constant Value: 3 (0x00000003)

STOP_REASON_UNDEFINED

public static final int STOP_REASON_UNDEFINED

There is no reason the job is stopped. This is the value returned from the JobParameters object passed to JobService.onStartJob(JobParameters).

Constant Value: 0 (0x00000000)

STOP_REASON_USER

public static final int STOP_REASON_USER

The user stopped the job. This can happen either through force-stop, adb shell commands, uninstalling, or some other UI.

Constant Value: 13 (0x0000000d)

CREATOR

public static final Creator<JobParameters> CREATOR

completeWork

public void completeWork (JobWorkItem work)

Report the completion of executing a JobWorkItem previously returned by dequeueWork(). This tells the system you are done with the work associated with that item, so it will not be returned again. Note that if this is the last work in the queue, completing it here will not finish the overall job -- for that to happen, you still need to call dequeueWork() again.

If you are enqueueing work into a job, you must call this method for each piece of work you process. Do not call JobService.jobFinished(JobParameters, boolean) or else you can lose work in your queue.

dequeueWork

public JobWorkItem dequeueWork ()

Dequeue the next pending JobWorkItem from these JobParameters associated with their currently running job. Calling this method when there is no more work available and all previously dequeued work has been completed will result in the system taking care of stopping the job for you -- you should not call JobService.jobFinished(JobParameters, boolean) yourself (otherwise you risk losing an upcoming JobWorkItem that is being enqueued at the same time).

Once you are done with the JobWorkItem returned by this method, you must call completeWork(android.app.job.JobWorkItem) with it to inform the system that you are done executing the work. The job will not be finished until all dequeued work has been completed. You do not, however, have to complete each returned work item before deqeueing the next one -- you can use dequeueWork() multiple times before completing previous work if you want to process work in parallel, and you can complete the work in whatever order you want.

If the job runs to the end of its available time period before all work has been completed, it will stop as normal. You should return true from JobService.onStopJob(JobParameters) in order to have the job rescheduled, and by doing so any pending as well as remaining uncompleted work will be re-queued for the next time the job runs.

This example shows how to construct a JobService that will serially dequeue and process work that is available for it:

public class JobWorkService extends JobService {
    private NotificationManager mNM;
    private CommandProcessor mCurProcessor;

    /**
     * This is a task to dequeue and process work in the background.
     */
    final class CommandProcessor extends AsyncTask<Void, Void, Void> {
        private final JobParameters mParams;

        CommandProcessor(JobParameters params) {
            mParams = params;
        }

        @Override
        protected Void doInBackground(Void... params) {
            boolean cancelled;
            JobWorkItem work;

            /**
             * Iterate over available work.  Once dequeueWork() returns null, the
             * job's work queue is empty and the job has stopped, so we can let this
             * async task complete.
             */
            while (!(cancelled=isCancelled()) && (work=mParams.dequeueWork()) != null) {
                String txt = work.getIntent().getStringExtra("name");
                Log.i("JobWorkService", "Processing work: " + work + ", msg: " + txt);
                showNotification(txt);

                // Process work here...  we'll pretend by sleeping.
                try {
                    Thread.sleep(5000);
                } catch (InterruptedException e) {
                }

                hideNotification();

                // Tell system we have finished processing the work.
                Log.i("JobWorkService", "Done with: " + work);
                mParams.completeWork(work);
            }

            if (cancelled) {
                Log.i("JobWorkService", "CANCELLED!");
            }

            return null;
        }
    }

        mNM = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
        Toast.makeText(this, R.string.service_created, Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onDestroy() {
        hideNotification();
        Toast.makeText(this, R.string.service_destroyed, Toast.LENGTH_SHORT).show();
    }

    @Override
    public boolean onStartJob(JobParameters params) {
        // Start task to pull work out of the queue and process it.
        mCurProcessor = new CommandProcessor(params);
        mCurProcessor.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);

        // Allow the job to continue running while we process work.
        return true;
    }

    @Override
    public boolean onStopJob(JobParameters params) {
        // Have the processor cancel its current work.
        mCurProcessor.cancel(true);

        // Tell the system to reschedule the job -- the only reason we would be here is
        // because the job needs to stop for some reason before it has completed all of
        // its work, so we would like it to remain to finish that work in the future.
        return true;
    }

    /**
     * Show a notification while this service is running.
     */
    private void showNotification(String text) {
        // The PendingIntent to launch our activity if the user selects this notification
        PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                new Intent(this, JobWorkServiceActivity.class), 0);

        // Set the info for the views that show in the notification panel.
        Notification.Builder noteBuilder = new Notification.Builder(this)
                .setSmallIcon(R.drawable.stat_sample)  // the status icon

        noteBuilder.setOngoing(true);

        // Send the notification.

}

describeContents

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

getClipData

public ClipData getClipData ()

getClipGrantFlags

public int getClipGrantFlags ()

getExtras

public PersistableBundle getExtras ()

getJobId

public int getJobId ()

getJobNamespace

public String getJobNamespace ()

Get the namespace this job was placed in.

getNetwork

public Network getNetwork ()

Return the network that should be used to perform any network requests for this job.

Devices may have multiple active network connections simultaneously, or they may not have a default network route at all. To correctly handle all situations like this, your job should always use the network returned by this method instead of implicitly using the default network route.

Note that the system may relax the constraints you originally requested, such as allowing a JobInfo.NETWORK_TYPE_UNMETERED job to run over a metered network when there is a surplus of metered data available. Starting in Android version Build.VERSION_CODES.UPSIDE_DOWN_CAKE, this will return null if the app does not hold the permissions specified in JobInfo.Builder.setRequiredNetwork(NetworkRequest).

getStopReason

public int getStopReason ()

Returns the reason JobService.onStopJob(JobParameters) was called on this job.

Apps should not rely on the stop reason for critical decision-making, as additional stop reasons may be added in subsequent Android releases. The primary intended use of this method is for logging and diagnostic purposes to gain insights into the causes of job termination.

getTransientExtras

public Bundle getTransientExtras ()

getTriggeredContentAuthorities

public String[] getTriggeredContentAuthorities ()

For jobs with JobInfo.Builder.addTriggerContentUri(TriggerContentUri) set, this reports which content authorities have triggered the job. It will only be null if no authorities have triggered it -- that is, the job executed for some other reason, such as a deadline expiring. If this is non-null, you can use getTriggeredContentUris() to retrieve the details of which URIs changed (as long as that has not exceeded the maximum number it can reported).

getTriggeredContentUris

public Uri[] getTriggeredContentUris ()

For jobs with JobInfo.Builder.addTriggerContentUri(TriggerContentUri) set, this reports which URIs have triggered the job. This will be null if either no URIs have triggered it (it went off due to a deadline or other reason), or the number of changed URIs is too large to report. Whether or not the number of URIs is too large, you can always use getTriggeredContentAuthorities() to determine whether the job was triggered due to any content changes and the authorities they are associated with.

isExpeditedJob

public boolean isExpeditedJob ()

isOverrideDeadlineExpired

public boolean isOverrideDeadlineExpired ()

For jobs with JobInfo.Builder.setOverrideDeadline(long) set, this provides an easy way to tell whether the job is being executed due to the deadline expiring. Note: If the job is running because its deadline expired, it implies that its constraints will not be met. However, periodic jobs will only ever run when their constraints are satisfied, therefore, the constraints will still be satisfied for a periodic job even if the deadline has expired.

isUserInitiatedJob

public boolean isUserInitiatedJob ()

writeToParcel

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.
