@Deprecated
public abstract class JobService
extends android.app.Service

JobService is the fundamental unit of work used in the JobDispatcher.

Users will need to override onStartJob(JobParameters), which is where any asynchronous execution should start. This method, like most lifecycle methods, runs on the main thread; you must offload execution to another thread (or AsyncTask, or Handler, or your favorite flavor of concurrency).

Once any asynchronous work is complete jobFinished(JobParameters, boolean) should be called to inform the backing driver of the result.

Implementations should also override onStopJob(JobParameters), which will be called if the scheduling engine wishes to interrupt your work (most likely because the runtime constraints that are associated with the job in question are no longer met).

Field Detail

RESULT_SUCCESS

public static final int RESULT_SUCCESS

Deprecated.

Returned to indicate the job was executed successfully. If the job is not recurring (i.e. a one-off) it will be dequeued and forgotten. If it is recurring the trigger will be reset and the job will be requeued.

RESULT_FAIL_RETRY

public static final int RESULT_FAIL_RETRY

Deprecated.

Returned to indicate the job encountered an error during execution and should be retried after a backoff period.

Deprecated.

Returned to indicate the job encountered an error during execution but should not be retried. If the job is not recurring (i.e. a one-off) it will be dequeued and forgotten. If it is recurring the trigger will be reset and the job will be requeued.

Constructor Detail

JobService

public JobService()

Deprecated.

Method Detail

onStartJob

public abstract boolean onStartJob(JobParameters job)

Deprecated.

The entry point to your Job. Implementations should offload work to another thread of execution as soon as possible because this runs on the main thread. If work was offloaded, call jobFinished(JobParameters, boolean) to notify the scheduling service that the work is completed.

If a job with the same service and tag was rescheduled during execution onStopJob(JobParameters) will be called and the wakelock will be released. Please make sure that all reschedule requests happen at the end of the job.

Returns:

true if there is more work remaining in the worker thread, false if the job was completed.

onStopJob

public abstract boolean onStopJob(JobParameters job)

Deprecated.

Called when the scheduling engine has decided to interrupt the execution of a running job, most likely because the runtime constraints associated with the job are no longer satisfied. The job must stop execution.

Returns:

true if the job should be retried

See Also:

JobInvocation.Builder.setRetryStrategy(RetryStrategy), RetryStrategy

jobFinished

public final void jobFinished(JobParameters job,
                              boolean needsReschedule)

Deprecated.

Callback to inform the scheduling driver that you've finished executing. Can be called from any thread. When the system receives this message, it will release the wakelock being held.

Parameters:

job -

needsReschedule - whether the job should be rescheduled

See Also:

JobInvocation.Builder.setRetryStrategy(RetryStrategy)
