Firebase JobDispatcher的调度不正确

Question

我必须使用按钮上的JobDispatcher启动后台服务。我有一个带有很多片段的Activity，并且在我的一个片段中有一个按钮，该按钮应该在按钮单击后的10秒内调用后台服务，但是一旦我的应用程序启动，该服务就会启动。它应该在单击按钮之后开始，但是应该在单击按钮之前开始。

单击按钮后应显示吐司。请参阅下面我至今尝试过的代码。

服务等级

public class DayJobService extends JobService {
    ExpenseClass expenseClass;
    DatabaseReference dbref;
    String username,currentdate,monthyr,expensesname,totaltxt;
    Context context;

    public DayJobService(){

    }
    @Override
    public boolean onStartJob(final JobParameters job) {
        Log.d("Started JOb","job started success");
        Toast.makeText(getApplicationContext(),"JOB STARTED",Toast.LENGTH_SHORT).show();
        return false;
    }

    @Override
    public boolean onStopJob(JobParameters job) {
        return true;
    }

清单

<service
        android:exported="false"
        android:name=".JobService.DayJobService">
        <intent-filter>
            <action android:name="com.firebase.jobdispatcher.ACTION_EXECUTE"/>
        </intent-filter>
    </service>

FragmentClass

public class DayExpensesFragment extends Fragment implements RecyclerItemTouchHelper.RecyclerItemTouchHelperListener{
     @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_day_expenses, container, false);
    startBtn=(Button)view.findViewById(R.id.startJob);
     firebaseJobDispatcher=new FirebaseJobDispatcher(new 
    GooglePlayDriver(getContext()));
    startBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startJob();
            }
        });
    }

     public void startJob(){
        Job job=firebaseJobDispatcher.newJobBuilder().
                setService(DayJobService.class).setTag(DAY_JOB_TAG).setLifetime(Lifetime.FOREVER).
                setRecurring(true).setTrigger(Trigger.executionWindow(10,15)).
                setRetryStrategy(RetryStrategy.DEFAULT_EXPONENTIAL).setReplaceCurrent(false).
                setConstraints(Constraint.ON_ANY_NETWORK).build();
        firebaseJobDispatcher.mustSchedule(job);

    }
}
