java.lang.NumberFormatException: Invalid int: ""

I have a problem with debugging my code. I'm getting java.lang.NumberFormatException: Invalid int: "" error at line 88 which is Calendar c = Calendar.getInstance();. I dont' understand how the Calendar instance can produce such error.

WakefulReceiverWorker.java: 

    Calendar c = Calendar.getInstance();   // <----- line 88
    long newStart = c.getTimeInMillis() + 300000;
    AlarmManager mAlarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, randomInt, intent2,PendingIntent.FLAG_UPDATE_CURRENT);
    mAlarmManager.set(AlarmManager.RTC_WAKEUP, (newStart), pendingIntent);

logcat:

I've just tested the app on the Samsung Galaxy S3 (i9300) and the error is not present on this device. It seems that it is Huawei's software problem.

Try instantiating your Calendar this way:

Locale locale = Locale.getDefault();
System.out.println("Locale is : [" + locale + "]"); // make sure there is a default Locale
Calendar calendar = Calendar.getInstance(locale);

----- Update ------
If you go through the stack trace, it looks like this is the culprit:

12-13 19:57:01.639    2070-2085/com.example.app W/System.err﹕ at java.util.Calendar.getHwFirstDayOfWeek(Calendar.java:807)

Because the next line in the stack trace starts parsing the integer, presumably the value returned by getHwFirstDayOfWeek().

Try this:

  Calendar calendar = new GregorianCalendar();

Not sure why yours isn't working, but Calendar is an Abstract class, so it might work better if you try GregorianCalendar.
