java.lang.Object | |
↳ | android.app.job.JobWorkItem |
A unit of work that can be enqueued for a job using
JobScheduler.enqueue
. See
JobParameters.dequeueWork
for more details.
Note: Prior to Android version
Build.VERSION_CODES.UPSIDE_DOWN_CAKE
, JobWorkItems could not be persisted.
Apps were not allowed to enqueue JobWorkItems with persisted jobs and the system would throw
an IllegalArgumentException
if they attempted to do so. Starting with
Build.VERSION_CODES.UPSIDE_DOWN_CAKE
, JobWorkItems can be persisted alongside
the hosting job. However, Intents cannot be persisted. Set a PersistableBundle
using
Builder.setExtras(PersistableBundle)
for any information that needs to be persisted.

Public methods
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.
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 |
getDeliveryCount
public int getDeliveryCount ()
Return the count of the number of times this work item has been delivered
to the job. The value will be > 1 if it has been redelivered because the job
was stopped or crashed while it had previously been delivered but before the
job had called JobParameters.completeWork
for it.
Returns | |
---|---|
int |
getEstimatedNetworkDownloadBytes
public long getEstimatedNetworkDownloadBytes ()
Return the estimated size of download traffic that will be performed by
this job, in bytes.
Value is a non-negative number of bytes.
Returns | |
---|---|
long |
Estimated size of download traffic, or
JobInfo.NETWORK_BYTES_UNKNOWN when unknown.
Value is a non-negative number of bytes. |
getEstimatedNetworkUploadBytes
public long getEstimatedNetworkUploadBytes ()
Return the estimated size of upload traffic that will be performed by
this job work item, in bytes.
Value is a non-negative number of bytes.
Returns | |
---|---|
long |
Estimated size of upload traffic, or
JobInfo.NETWORK_BYTES_UNKNOWN when unknown.
Value is a non-negative number of bytes. |
getExtras
public PersistableBundle getExtras ()
Return the extras associated with this work.
Returns | |
---|---|
PersistableBundle |
This value cannot be null . |
getIntent
public Intent getIntent ()
Return the Intent associated with this work.
Returns | |
---|---|
Intent |

public long getMinimumNetworkChunkBytes ()
Return the smallest piece of data that cannot be easily paused and resumed, in bytes.
Value is a non-negative number of bytes.
Returns | |
---|---|
long |
Smallest piece of data that cannot be easily paused and resumed, or

Value is a non-negative number of bytes. |
toString
public String toString ()
Returns a string representation of the object.
Returns | |
---|---|
String |
a string representation of the object. |
writeToParcel
public void writeToParcel (Parcel out, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
out |
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 .
