JobInfo

public class JobInfo
extends Object implements Parcelable

java.lang.Object
   ↳ android.app.job.JobInfo


Container of data passed to the 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.

Summary

Nested classes

class JobInfo.Builder

Builder class for constructing JobInfo objects. 

class JobInfo.TriggerContentUri

Information about a content URI modification that a job would like to trigger on.

Constants

BACKOFF_POLICY_EXPONENTIAL

Added in API level 21
public static final int BACKOFF_POLICY_EXPONENTIAL

Exponentially back-off a failed job. See JobInfo.Builder.setBackoffCriteria(long, int) retry_time(current_time, num_failures) = current_time + initial_backoff_millis * 2 ^ (num_failures - 1), num_failures >= 1

Constant Value: 1 (0x00000001)

BACKOFF_POLICY_LINEAR

Added in API level 21
public static final int BACKOFF_POLICY_LINEAR

Linearly back-off a failed job. See JobInfo.Builder.setBackoffCriteria(long, int) retry_time(current_time, num_failures) = current_time + initial_backoff_millis * num_failures, num_failures >= 1

Constant Value: 0 (0x00000000)

DEFAULT_INITIAL_BACKOFF_MILLIS

Added in API level 21
public static final long DEFAULT_INITIAL_BACKOFF_MILLIS

Amount of backoff a job has initially by default, in milliseconds.

Constant Value: 30000 (0x0000000000007530)

MAX_BACKOFF_DELAY_MILLIS

Added in API level 21
public static final long MAX_BACKOFF_DELAY_MILLIS

Maximum backoff we allow for a job, in milliseconds.

Constant Value: 18000000 (0x000000000112a880)

NETWORK_BYTES_UNKNOWN

Added in API level 28
public static final int NETWORK_BYTES_UNKNOWN

Sentinel value indicating that bytes are unknown.

Constant Value: -1 (0xffffffff)

NETWORK_TYPE_ANY

Added in API level 21
public static final int NETWORK_TYPE_ANY

This job requires network connectivity.

Constant Value: 1 (0x00000001)

NETWORK_TYPE_CELLULAR

Added in API level 28
public static final int NETWORK_TYPE_CELLULAR

This job requires network connectivity that is a cellular network.

Constant Value: 4 (0x00000004)

NETWORK_TYPE_METERED

Added in API level 26
Deprecated in API level 28
public static final int NETWORK_TYPE_METERED

This constant was deprecated in API level 28.
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 NetworkRequest.Builder.addTransportType(int) if your job requires a specific network transport.

This job requires metered connectivity such as most cellular data networks.

Constant Value: 4 (0x00000004)

NETWORK_TYPE_NONE

Added in API level 21
public static final int NETWORK_TYPE_NONE

Default.

Constant Value: 0 (0x00000000)

NETWORK_TYPE_NOT_ROAMING

Added in API level 24
public static final int NETWORK_TYPE_NOT_ROAMING

Constant Value: 3 (0x00000003)

NETWORK_TYPE_UNMETERED

Added in API level 21
public static final int NETWORK_TYPE_UNMETERED

PRIORITY_DEFAULT

Added in API level 33
public static final int PRIORITY_DEFAULT

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.

Constant Value: 300 (0x0000012c)

PRIORITY_HIGH

Added in API level 33
public static final int PRIORITY_HIGH

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.

Constant Value: 400 (0x00000190)

PRIORITY_LOW

Added in API level 33
public static final int PRIORITY_LOW

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

Constant Value: 200 (0x000000c8)

PRIORITY_MAX

Added in API level 33
public static final int PRIORITY_MAX

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

Constant Value: 500 (0x000001f4)

PRIORITY_MIN

Added in API level 33
public static final int PRIORITY_MIN

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

Constant Value: 100 (0x00000064)

Fields

CREATOR

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

Public methods

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

equals

Added in API level 21
public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
o Object: the reference object with which to compare.

Returns
boolean true if this object is the same as the obj argument; false otherwise.

hashCode

Added in API level 21
public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns
int a hash code value for this object.
