Question

我在android应用中创建了一个firebase作业服务。

但是由于某种原因，它不会执行启动作业。

我运行android调试器来跟踪它，但是一旦创建了作业，就什么也没有发生。但是由于某种原因，它不会执行启动作业。

我已遵循本教程-

我一直在尽最大可能根据教程检查代码，我更新了清单以确保已添加服务。

public class AutomateJobs {
    private static final int REMINDER_MINUTES = 1;
    private static final int REMINDER_IN_SECONDS =  (int) (TimeUnit.MINUTES.toSeconds(REMINDER_MINUTES));
    private static final int FLEX_SECONDS = REMINDER_IN_SECONDS; // amount of seconds between each check

    private static final String REMINDER_JOB_TAG = "check_date_time_tag";
    private static boolean sInitialised;

    synchronized public static void runAutomateGamesCheck(@Nullable final Context context){
        if(sInitialised) return;
        Driver driver = new GooglePlayDriver(context);
        FirebaseJobDispatcher firebaseJobDispatcher = new FirebaseJobDispatcher(driver);
        Job constraintCheckDateTimeJob =  firebaseJobDispatcher.newJobBuilder()
                .setService(AutomateSendSms.class)
                .setTag(REMINDER_JOB_TAG)
                .setLifetime(Lifetime.FOREVER)
                .setRecurring(true)
                .setTrigger(Trigger.executionWindow(
                        REMINDER_IN_SECONDS,
                        REMINDER_IN_SECONDS + FLEX_SECONDS))
                .setReplaceCurrent(true) //if remade, replace the old one
                .build();
        firebaseJobDispatcher.schedule(constraintCheckDateTimeJob);
        sInitialised = true;
    }

然后在一个新的班上，我有一个刚开始的工作：

/Also, not sure why  com.firebase.jobdispatcher.JobService does not import,
//I tried to import at the top of my code, but it does not like it unless I have
//it set like this. I do have the correct implementation within my gradle

public class AutomateSendSms extends com.firebase.jobdispatcher.JobService { 

    private GameDetailsFromDatabase gameDetailsFromDatabase = new GameDetailsFromDatabase();
    SmsManager smsManager = SmsManager.getDefault();
    private Calendar calendar;
    private int mYear, mMonth, mDay, mHour, mMinute,mHourPlusOne;

    private SimpleDateFormat sdfCurrentDateTimePlusOne = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    private SimpleDateFormat sdfCurrentDateTimeFromDB = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    private Date currentDate,currentDatePlusOne,dateFromDB;
    private AsyncTask checkDateTime;

    @Override
    public boolean onStartJob(final com.firebase.jobdispatcher.JobParameters params) {
        checkDateTime =  new AsyncTask(){

            @Override
            protected Object doInBackground(Object[] objects) {
                listOfAllDateTimesToSendText = gameDetailsFromDatabase.agReturnDateTime();
                calendar = Calendar.getInstance();
                mYear = calendar.get(Calendar.YEAR);
                mMonth = calendar.get(Calendar.MONTH) + 1;

                } catch (ParseException e) {
                    e.printStackTrace();
                }
                try {
                    while (listOfAllDateTimesToSendText.moveToNext()) {
                        String dateTimeFromCursor = listOfAllDateTimesToSendText.getString(listOfAllDateTimesToSendText.getColumnIndex(MainAutomateGames.AutomateGamesTable.COLUMN_DATE_TO_SEND_TEXT));
                        try {
                            dateFromDB = sdfCurrentDateTimeFromDB.parse(dateTimeFromCursor);

    @Override

我在没有Google Play服务的模拟器上运行此程序。当我在真正的设备上尝试时，它可以工作。您必须选择支持Google Play的图片
