JobInfo
open class JobInfo : Parcelable
| kotlin.Any | |
| ↳ | android.app.job.JobInfo |
Container of data passed to the android.app.job.JobScheduler fully encapsulating the parameters required to schedule work against the calling application. These are constructed using the JobInfo.Builder. The goal here is to provide the scheduler with high-level semantics about the work you want to accomplish.
Prior to Android version Build.VERSION_CODES#Q, you had to specify at least one constraint on the JobInfo object that you are creating. Otherwise, the builder would throw an exception when building. From Android version Build.VERSION_CODES#Q and onwards, it is valid to schedule jobs with no constraints.

Constants
BACKOFF_POLICY_EXPONENTIAL
static val BACKOFF_POLICY_EXPONENTIAL: Int
Exponentially back-off a failed job. See android.app.job.JobInfo.Builder#setBackoffCriteria(long, int) retry_time(current_time, num_failures) = current_time + initial_backoff_millis * 2 ^ (num_failures - 1), num_failures >= 1
Value: 1BACKOFF_POLICY_LINEAR
static val BACKOFF_POLICY_LINEAR: Int
Linearly back-off a failed job. See android.app.job.JobInfo.Builder#setBackoffCriteria(long, int) retry_time(current_time, num_failures) = current_time + initial_backoff_millis * num_failures, num_failures >= 1
Value: 0DEFAULT_INITIAL_BACKOFF_MILLIS
static val DEFAULT_INITIAL_BACKOFF_MILLIS: Long
Amount of backoff a job has initially by default, in milliseconds.
Value: 30000LMAX_BACKOFF_DELAY_MILLIS
static val MAX_BACKOFF_DELAY_MILLIS: Long
Maximum backoff we allow for a job, in milliseconds.
Value: 18000000LNETWORK_BYTES_UNKNOWN
static val NETWORK_BYTES_UNKNOWN: Int
Sentinel value indicating that bytes are unknown.
Value: -1NETWORK_TYPE_ANY
static val NETWORK_TYPE_ANY: Int
This job requires network connectivity.
Value: 1NETWORK_TYPE_CELLULAR
static val NETWORK_TYPE_CELLULAR: Int
This job requires network connectivity that is a cellular network.
Value: 4NETWORK_TYPE_METERED
static valNETWORK_TYPE_METERED: Int
Deprecated: Cellular networks may be unmetered, or Wi-Fi networks may be metered, so this isn't a good way of selecting a specific transport. Instead, use NETWORK_TYPE_CELLULAR or android.net.NetworkRequest.Builder#addTransportType(int) if your job requires a specific network transport.
This job requires metered connectivity such as most cellular data networks.
Value: 4NETWORK_TYPE_NOT_ROAMING
static val NETWORK_TYPE_NOT_ROAMING: Int
This job requires network connectivity that is not roaming.
Value: 3NETWORK_TYPE_UNMETERED
static val NETWORK_TYPE_UNMETERED: Int
This job requires network connectivity that is unmetered.
Value: 2PRIORITY_DEFAULT
static val PRIORITY_DEFAULT: Int
Default value for all regular jobs. As noted in JobScheduler, these jobs have a general execution time of 10 minutes. Receives the standard job management policy.
Value: 300PRIORITY_HIGH
static val PRIORITY_HIGH: Int
This task should be ordered ahead of most other tasks. It may be deferred a little, but if it doesn't run at some point, the user may think something is wrong. Assuming all constraints remain satisfied (including ideal system load conditions), these jobs can have an execution time of at least 4 minutes. Setting all of your jobs to high priority will not be beneficial to your app and in fact may hurt its performance in the long run.
Value: 400PRIORITY_LOW
static val PRIORITY_LOW: Int
Low priority. The task provides some benefit to users, but is not critical and is more of a nice-to-have. This is more important than minimum priority jobs and will be prioritized ahead of them, but may still be deferred in lieu of higher priority jobs. JobScheduler may decide to defer these tasks while there are higher priority tasks in order to ensure there is sufficient quota available for the higher priority tasks. A sample task of low priority: prefetching data the user hasn't requested
Value: 200PRIORITY_MAX
static val PRIORITY_MAX: Int
This task is critical to user experience or functionality and should be run ahead of all other tasks. Only expedited jobs and user-initiated jobs can have this priority.
Example tasks of max priority:
- Receiving a text message and processing it to show a notification
- Downloading or uploading some content the user requested to transfer immediately
Value: 500PRIORITY_MIN
static val PRIORITY_MIN: Int
Job has minimal value to the user. The user has absolutely no expectation or knowledge of this task and it has no bearing on the user's perception of the app whatsoever. JobScheduler may decide to defer these tasks while there are higher priority tasks in order to ensure there is sufficient quota available for the higher priority tasks. A sample task of min priority: uploading analytics
Value: 100Public methods
