Java AlarmManager没有'；行不通

这是我的密码。直到昨天，这个代码仍然运行良好。正确调用了MyAlarmManager（我可以看到日志），但没有调用MyReceiver。你知道为什么吗

public class MyReceiver extends BroadcastReceiver
{ 
    @Override
    public void onReceive(Context context, Intent intent)
    {
       //It will start the application at a certain time
       Intent i = new Intent(context, Calibration.class);
       i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
       context.startActivity(i);
       Log.e("MyReceiver", "MyReceiver");
    }
}

这是AlarmManager类

public void onCreate() 
    {   
        //Start
        Intent myIntent = new Intent(this, MyReceiver.class);
        pendingIntent = PendingIntent.getBroadcast(this, 0, myIntent,0);
        AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
        pref = getApplicationContext().getSharedPreferences(
                "settings", MODE_PRIVATE);
        int h=pref.getInt("hour", -1);
        int m=pref.getInt("minute", -1);
        Calendar start=null;
        Calendar start2=null;
        //If the user added a time in the options activity, the application will start at that time
        if(h!=-1 && m!=-1)
        {
            if(pendingIntent != null) 
            {
               alarmManager.cancel(pendingIntent);
            }
            Log.e("h e m", h+" "+m);
            GregorianCalendar now = new GregorianCalendar();
            start = new GregorianCalendar();
            start.set(Calendar.HOUR_OF_DAY, h);
            start.set(Calendar.MINUTE, m);
            start.set(Calendar.SECOND, 0);
            if(h>=0 && h<12)
                start.set(Calendar.AM_PM,Calendar.AM);
            if(h>=12 && h<=23)
                start.set(Calendar.AM_PM,Calendar.PM);
            if(start.after(now))
            {
                alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, start.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
                alarmManager.set(AlarmManager.RTC, start.getTimeInMillis(), pendingIntent);
                Log.e("MyAlarmManager", "MyAlarmManager");
            }
        }
        //Start 2
        Intent myIntent2 = new Intent(this, MyReceiver.class);
        pendingIntent2 = PendingIntent.getBroadcast(this, 2, myIntent2,0);
        int h2=pref.getInt("hour2", -1);
        int m2=pref.getInt("minute2", -1);
        //If the user added a time in the options activity, the application will start at that time
        if(h2!=-1 && m2!=-1)
        {
            if(pendingIntent3 != null) 
            {
               alarmManager.cancel(pendingIntent2);
            }
            Log.e("h2 e m2", h2+" "+m2);
            GregorianCalendar now = new GregorianCalendar();
            start2 = new GregorianCalendar();
            start2.set(Calendar.HOUR_OF_DAY, h2);
            start2.set(Calendar.MINUTE, m2);
            start2.set(Calendar.SECOND, 0);
            if(h2>=0 && h2<12)
                start2.set(Calendar.AM_PM,Calendar.AM);
            if(h2>=12 && h2<=23)
                start2.set(Calendar.AM_PM,Calendar.PM);
            if(start2.after(now))
            {
                alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, start2.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent3);
                alarmManager.set(AlarmManager.RTC, start2.getTimeInMillis(), pendingIntent3);
                Log.e("MyAlarmManager3", "MyAlarmManager3");
            }
        }
    }

public void onCreate（）
{   
//开始
Intent myIntent=新的Intent（this，MyReceiver.class）；
pendingIntent=pendingIntent.getBroadcast（this，0，myIntent，0）；
AlarmManager AlarmManager=（AlarmManager）getSystemService（报警服务）；
pref=getApplicationContext（）.GetSharedReferences(
“设置”，模式（私人）；
inth=pref.getInt（“小时”，-1）；
int m=pref.getInt（“分钟”，-1）；
日历开始=空；
日历开始时间2=空；
//如果用户在“选项”活动中添加了时间，则应用程序将在该时间启动
if（h！=-1&&m！=-1）
{
如果（PendingEvent！=null）
{
alarmManager.cancel（挂起事件）；
}
Log.e（“hem”，h+“”+m）；
GregorianCalendar now=新的GregorianCalendar（）；
开始=新的GregorianCalendar（）；
开始.设置（日历.小时/天，小时）；
开始.设置（日历.分钟，m）；
开始。设置（日历秒，0）；
如果（h>=0&&h=12&&h=0&&h=12&&h2=12&&h2）你想在Android 4.4中运行代码吗？avd有Android 4.0，我的设备有Android 2.1（直到昨天还运行得很好）。我觉得一切都很好。你对代码或Android清单文件做了任何更改吗？还有，
pendingIntent3
？没有问题。编码愉快！！！
