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:
