Fields

CREATOR

Added in API level 21
public static final Creator<JobParameters> CREATOR

Public methods

completeWork

Added in API level 26
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.

Parameters
work JobWorkItem: The work you have completed processing, as previously returned by dequeueWork() This value cannot be null.

dequeueWork

Added in API level 26
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;
        }
    }

    @Override
    public void onCreate() {
        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
                .setTicker(text)  // the status text
                .setWhen(System.currentTimeMillis())  // the time stamp
                .setContentTitle(getText(R.string.service_start_arguments_label))  // the label

        noteBuilder.setOngoing(true);

        // Send the notification.
        // We use a string id because it is a unique number.  We use it later to cancel.

    }

    private void hideNotification() {
        mNM.cancel(R.string.service_created);
    }
}

Returns
JobWorkItem Returns a new JobWorkItem if there is one pending, otherwise null. If null is returned, the system will also stop the job if all work has also been completed. (This means that for correct operation, you must always call dequeueWork() after you have completed other work, to check either for more work or allow the system to stop the job.)

describeContents

Added in API level 21
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.

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or CONTENTS_FILE_DESCRIPTOR

getClipData

Added in API level 26
public ClipData getClipData ()

Returns
ClipData The clip you passed in when constructing this job with JobInfo.Builder.setClipData(ClipData, int). Will be null if it was not set.

getClipGrantFlags

Added in API level 26
public int getClipGrantFlags ()

Returns
int The clip grant flags you passed in when constructing this job with JobInfo.Builder.setClipData(ClipData, int). Will be 0 if it was not set.

getExtras

Added in API level 21
public PersistableBundle getExtras ()

Returns
PersistableBundle The extras you passed in when constructing this job with JobInfo.Builder.setExtras(android.os.PersistableBundle). This will never be null. If you did not set any extras this will be an empty bundle.

getJobId

Added in API level 21
public int getJobId ()

Returns
int The unique id of this job, specified at creation time.

getJobNamespace

Added in API level 34
public String getJobNamespace ()

Get the namespace this job was placed in.

Returns
String The namespace this job was scheduled in. Will be null if there was no explicit namespace set and this job is therefore in the default namespace.

getNetwork

Added in API level 28
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).

Returns
Network the network that should be used to perform any network requests for this job, or null if this job didn't set any required network type or if the job executed when there was no available network to use.

getTransientExtras

Added in API level 26
public Bundle getTransientExtras ()

Returns
Bundle The transient extras you passed in when constructing this job with JobInfo.Builder.setTransientExtras(android.os.Bundle). This will never be null. If you did not set any extras this will be an empty bundle.

getTriggeredContentAuthorities

Added in API level 24
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).

Returns
String[]

getTriggeredContentUris

Added in API level 24
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.

Returns
Uri[]

isExpeditedJob

Added in API level 31
public boolean isExpeditedJob ()

Returns
boolean Whether this job is running as an expedited job or not. A job is guaranteed to have all expedited job guarantees for the duration of the job execution if this returns true. This will return false if the job that wasn't requested to run as a expedited job, or if it was requested to run as an expedited job but the app didn't have any remaining expedited job quota at the time of execution.

isOverrideDeadlineExpired

Added in API level 21
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.

Returns
boolean

isUserInitiatedJob

Added in API level 34
public boolean isUserInitiatedJob ()

Returns
boolean Whether this job is running as a user-initiated job or not. A job is guaranteed to have all user-initiated job guarantees for the duration of the job execution if this returns true. This will return false if the job wasn't requested to run as a user-initiated job, or if it was requested to run as a user-initiated job but the app didn't meet any of the requirements at the time of execution, such as having the Manifest.permission.RUN_USER_INITIATED_JOBS permission.

writeToParcel

Added in API level 21
public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
dest Parcel: The Parcel in which the object should be written. This value cannot be null.

flags int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE. Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
