# Class WorkRequest

java.lang.Object
com.codename1.background.WorkRequest

public final class WorkRequest extends Object

Describes a unit of constraint-aware background work to be scheduled with `BackgroundWork#schedule(WorkRequest)`. The constraints map to Android WorkManager constraints and iOS `BGTaskScheduler` request options.

Input data is a string-keyed string map so that it can survive serialization into the platform scheduler and a subsequent cold launch of the app process.

Usage

    WorkRequest req = WorkRequest.builder("sync", SyncWorker.class)
            .setRequiresNetwork(true)
            .setRequiresCharging(true)
            .setPeriodic(6 * 60 * 60 * 1000L)
            .putInputData("account", "primary")
            .build();
    BackgroundWork.schedule(req);

  - ### builder

    public static WorkRequest.Builder builder(String id, Class<? extends BackgroundWorker> worker)

    Creates a new work request builder.

    ###### Parameters

    - `id`: a stable unique id for the work; scheduling another request with the same id replaces it

    - `worker`: the worker class that performs the work; it must have a public no-arg constructor

    ###### Returns

    a new builder
