java - Firebase JobDispatcher 在 1 小时后停止工作

Question

在 API > 21 上，当我的手机锁定时，此服务将停止工作(当我唤醒手机时，服务将开始工作)。这就是我所做的:

public class JobDispacherService extends JobService {

    private Preferences prefs = null;
    public static final String GCM_ONEOFF_TAG = "oneoff|[0,0]";
    public static final String GCM_REPEAT_TAG = "komunalRepeat|[7200,1800]";
    private static final String TAG = JobDispacherService.class.getSimpleName();
    private UplaudPossitionTask uplaudPossitionTask;

    @Override
    public boolean onStartJob(@NonNull JobParameters job) {

        uplaudPossitionTask = new UplaudPossitionTask() {
            @Override
            protected void onPostExecute(Void aVoid) {
                super.onPostExecute(aVoid);
                jobFinished(job, false);
            }
        };
        uplaudPossitionTask.execute();
        return false; // Answers the question: "Is there still work going on?"
    }


    @Override
    public boolean onStopJob(JobParameters job) {
        return true; // Answers the question: "Should this job be retried?"
    }

    private class UplaudPossitionTask extends AsyncTask<Void, Void, Void> {

        @Override
        protected Void doInBackground(Void... params) {

            uploadPosition();
            return null;
        }
    }

}

我这样称呼这个服务:

  FirebaseJobDispatcher dispatcher = new FirebaseJobDispatcher(new GooglePlayDriver(context));

        Job myJob = dispatcher.newJobBuilder()
                .setService(JobDispacherService.class)
                .setTag("my-unique-tag")
                .setRecurring(true)
                .setLifetime(Lifetime.FOREVER)
                .setTrigger(Trigger.executionWindow(10, (int) 15))
                .setReplaceCurrent(false)
                .setRetryStrategy(RetryStrategy.DEFAULT_EXPONENTIAL)
                .setConstraints(Constraint.ON_ANY_NETWORK)
                .build();

        dispatcher.mustSchedule(myJob);

我想一直重复这个时间，但我不知道为什么当我的手机锁定超过 1 小时时此服务停止工作

工作管理器:

public static void refreshCouponPeriodicWork() {

    //define constraints
    Constraints myConstraints = new Constraints.Builder()
            .setRequiresDeviceIdle(false)
            .setRequiresCharging(false)
            .setRequiredNetworkType(NetworkType.CONNECTED)
            .setRequiresBatteryNotLow(true)
            .setRequiresStorageNotLow(true)
            .build();

    Data source = new Data.Builder()
            .putString("workType", "PeriodicTime")
            .build();

    PeriodicWorkRequest refreshCpnWork =
            new PeriodicWorkRequest.Builder(RefreshLatestCouponWorker.class, 10, TimeUnit.HOURS,30, TimeUnit.SECONDS)
                    .setConstraints(myConstraints)
                    .setInputData(source)
                    .build();

    WorkManager.getInstance().enqueue(refreshCpnWork);
}


public class RefreshLatestCouponWorker extends Worker {

    private Preferences prefs = null;


    public RefreshLatestCouponWorker(@NonNull Context context, @NonNull WorkerParameters workerParams) {
        super(context, workerParams);
    }

    @NonNull
    @Override
    public Worker.Result doWork() {
        //read input argument
        String workType = getInputData().getString("workType");
        Log.i("refresh cpn work", "type of work request: " + workType);

        uploadPosition();
        //sending work status to caller
        return success();
    }

}

我为工作经理执行此操作，但任务仅运行一次并且从不重复

我建议您阅读有关 WorkManager 的内容，这将是适合您的正确解决方案。 WorkManager API 可以轻松安排可延迟的异步任务，即使应用程序退出或设备重新启动，这些任务也将运行。您可以定义具有指定时间间隔和设备状态的定期请求。如果您发现实现困难，请恢复，我可以帮助您。
