使用

// 1、定义任务
public class MyWorker extends Worker {

    @NonNull
    @Override
    public Result doWork() {
        String data = getInputData().getString("workerData");
        Log.i("MyWorker","doWork:"+data);
        return Result.SUCCESS;
    }
}

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // 1、执行时机
        Constraints mConstraints = new Constraints.Builder()
                .setRequiresBatteryNotLow(true) //不在电量不足时执行
                .setRequiresCharging(true) //在充电时执行
                .setRequiresStorageNotLow(true) //不在存储容量不足时执行
                .setRequiresDeviceIdle(true) //在待机状态执行
                .build();

        // 2、数据
        Data data = new Data.Builder().putString("workerData","helloWorld").build();

        // 3、构建任务
        OneTimeWorkRequest request = new OneTimeWorkRequest.Builder(MyWorker.class)
                .setInputData(data)
                .setInitialDelay(5, TimeUnit.SECONDS)
                .build();

        // 4、任务加入队列
        WorkManager.getInstance().enqueue(request);
    }
}
