java.lang.NumberFormatException: Invalid int: ""
android, java
Solution
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.
Problem
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: ``` 12-13 19:57:01.589 2070-2085/com.example.app W/System.err﹕ java.lang.NumberFormatException: Invalid int: "" 12-13 19:57:01.619 2070-2085/com.example.app W/System.err﹕ at java.lang.Integer.invalidInt(Integer.java:138) 12-13 19:57:01.629 2070-2085/com.example.app W/System.err﹕ at java.lang.Integer.parseInt(Integer.java:359) 12-13 19:57:01.639 2070-2085/com.example.app W/System.err﹕ at java.lang.Integer.parseInt(Integer.java:332) 12-13 19:57:01.639 2070-2085/com.example.app W/System.err﹕ at java.util.Calendar.getHwFirstDayOfWeek(Calendar.java:807) 12-13 19:57:01.639 2070-2085/com.example.app W/System.err﹕ at java.util.Calendar.<init>(Calendar.java:745) 12-13 19:57:01.639 2070-2085/com.example.app W/System.err﹕ at java.util.GregorianCalendar.<init>(GregorianCalendar.java:338) 12-13 19:57:01.649 2070-2085/com.example.app W/System.err﹕ at java.util.GregorianCalendar.<init>(GregorianCalendar.java:239) 12-13 19:57:01.649 2070-2085/com.example.app W/System.err﹕ at java.util.Calendar.getInstance(Calendar.java:1086) 12-13 19:57:01.649 2070-2085/com.example.app W/System.err﹕ at com.example.app.WakefulReceiverWorker.onHandleIntent(WakefulReceiverWorker.java:88) 12-13 19:57:01.659 2070-2085/com.example.app W/System.err﹕ at android.app.IntentService$ServiceHandler.handleMessage(IntentService.java:65) 12-13 19:57:01.659 2070-2085/com.example.app W/System.err﹕ at android.os.Handler.dispatchMessage(Handler.java:99) 12-13 19:57:01.659 2070-2085/com.example.app W/System.err﹕ at android.os.Looper.loop(Looper.java:137) 12-13 19:57:01.659 2070-2085/com.example.app W/System.err﹕ at android.os.HandlerThread.run(HandlerThread.java:60) ```
