java.lang.NumberFormatException:无效的int:""

Question

我在调试代码时遇到问题.我java.lang.NumberFormatException: Invalid int: ""在第88行遇到错误Calendar c = Calendar.getInstance();.我不明白Calendar实例如何产生这样的错误.

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的:

我刚刚在 Samsung Galaxy S3 (i9300) 上测试了该应用程序，该设备上不存在该错误。看来是华为的软件问题。
