Public methods

addContentUriTrigger

public Constraints.Builder addContentUriTrigger (Uri uri, 
                boolean triggerForDescendants)

Sets whether the WorkRequest should run when a local content: Uri is updated. This functionality is identical to the one found in JobScheduler and is described in JobInfo.Builder#addTriggerContentUri(android.app.job.JobInfo.TriggerContentUri).

Parameters
`uri`	`Uri`: The local `content:` Uri to observe
`triggerForDescendants`	`boolean`: `true` if any changes in descendants cause this `WorkRequest` to run

Returns
`Constraints.Builder`	The current `Constraints.Builder`

build

public Constraints build ()

Generates the Constraints from this Builder.

Returns
`Constraints`	The `Constraints` specified by this Builder

setRequiredNetworkType

public Constraints.Builder setRequiredNetworkType (NetworkType networkType)

Sets whether device should have a particular NetworkType for the WorkRequest to run. The default value is NetworkType.NOT_REQUIRED.

Parameters
`networkType`	`NetworkType`: The type of network required for the work to run

Returns
`Constraints.Builder`	The current `Constraints.Builder`

setRequiresBatteryNotLow

public Constraints.Builder setRequiresBatteryNotLow (boolean requiresBatteryNotLow)

Sets whether device battery should be at an acceptable level for the WorkRequest to run. The default value is false.

Parameters
`requiresBatteryNotLow`	`boolean`: `true` if the battery should be at an acceptable level for the work to run

Returns
`Constraints.Builder`	The current `Constraints.Builder`

setRequiresCharging

public Constraints.Builder setRequiresCharging (boolean requiresCharging)

Sets whether device should be charging for the WorkRequest to run. The default value is false.

Parameters
`requiresCharging`	`boolean`: `true` if device must be charging for the work to run

Returns
`Constraints.Builder`	The current `Constraints.Builder`

setRequiresDeviceIdle

public Constraints.Builder setRequiresDeviceIdle (boolean requiresDeviceIdle)

Sets whether device should be idle for the WorkRequest to run. The default value is false.

Parameters
`requiresDeviceIdle`	`boolean`: `true` if device must be idle for the work to run

Returns
`Constraints.Builder`	The current `Constraints.Builder`

setRequiresStorageNotLow

public Constraints.Builder setRequiresStorageNotLow (boolean requiresStorageNotLow)

Sets whether the device's available storage should be at an acceptable level for the WorkRequest to run. The default value is false.

Parameters
`requiresStorageNotLow`	`boolean`: `true` if the available storage should not be below a a critical threshold for the work to run

Returns
`Constraints.Builder`	The current `Constraints.Builder`

setTriggerContentMaxDelay

public Constraints.Builder setTriggerContentMaxDelay (Duration duration)

Sets the maximum delay that is allowed from the first time a content: Uri change is detected to the time when the WorkRequest is scheduled. This functionality is identical to the one found in JobScheduler and is described in JobInfo.Builder#setTriggerContentMaxDelay(long).

Parameters
`duration`	`Duration`: The length of the delay

Returns
`Constraints.Builder`	The current `Constraints.Builder`

setTriggerContentMaxDelay

public Constraints.Builder setTriggerContentMaxDelay (long duration, 
                TimeUnit timeUnit)

Parameters
`duration`	`long`: The length of the delay in `timeUnit` units
`timeUnit`	`TimeUnit`: The units of time for `duration`

Returns
`Constraints.Builder`	The current `Constraints.Builder`

setTriggerContentUpdateDelay

public Constraints.Builder setTriggerContentUpdateDelay (long duration, 
                TimeUnit timeUnit)

Sets the delay that is allowed from the time a content: Uri change is detected to the time when the WorkRequest is scheduled. If there are more changes during this time, the delay will be reset to the start of the most recent change. This functionality is identical to the one found in JobScheduler and is described in JobInfo.Builder#setTriggerContentUpdateDelay(long).

Parameters
`duration`	`long`: The length of the delay in `timeUnit` units
`timeUnit`	`TimeUnit`: The units of time for `duration`

Returns
`Constraints.Builder`	The current `Constraints.Builder`

setTriggerContentUpdateDelay

public Constraints.Builder setTriggerContentUpdateDelay (Duration duration)

Parameters
`duration`	`Duration`: The length of the delay

Returns
`Constraints.Builder`	The current `Constraints.Builder`
