java - GreenRobot Exception : de.greenrobot.event.EventBusException: Invoking subscriber failed -

-

time time exception.

i use green-robot standard way, between views, fragments, activities, services , app, default instance, , time time stickyevents.

i did't find other post related exception. idea, or hint start investigation ?

the event bus working nicely (~ 20 events, 10 subscribers), user triggered no big workload in field.

the complete stack-trace here :

de.greenrobot.event.eventbusexception: invoking subscriber failed 10-27 15:37:00.522 25414-25414/fr.tech.app..u e/androidruntime:     @ de.greenrobot.event.eventbus.handlesubscriberexception(eventbus.java:518) 10-27 15:37:00.522 25414-25414/fr.tech.app..u e/androidruntime:     @ de.greenrobot.event.eventbus.invokesubscriber(eventbus.java:500) 10-27 15:37:00.522 25414-25414/fr.tech.app..u e/androidruntime:     @ de.greenrobot.event.eventbus.posttosubscription(eventbus.java:429) 10-27 15:37:00.522 25414-25414/fr.tech.app..u e/androidruntime:     @ de.greenrobot.event.eventbus.postsingleeventforeventtype(eventbus.java:410) 10-27 15:37:00.522 25414-25414/fr.tech.app..u e/androidruntime:     @ de.greenrobot.event.eventbus.postsingleevent(eventbus.java:383) 10-27 15:37:00.522 25414-25414/fr.tech.app..u e/androidruntime:     @ de.greenrobot.event.eventbus.post(eventbus.java:263) 10-27 15:37:00.522 25414-25414/fr.tech.app..u e/androidruntime:     @ fr.u.app.u.dialog.tastingnavigationdialog$1.onselection(tastingnavigationdialog.java:42)

error triggered materialdialog instance :

  dialogbuilder = new materialdialog.builder(context)             .title(r.string.dialogtastingnavigationtriptitle)             .negativetext(r.string.buttoncancel)             .cancelable(false)             .adapter(listadapter, new materialdialog.listcallback() {                 @override                 public void onselection(materialdialog dialog, view itemview, int which, charsequence text) {                     eventbus.getdefault().post(new tastingpagetoevent(listadapter.list.get(which), which));                     dialog.dismiss();                 }             });

edit

i found 1 thing trigger exception, posting 1 stickyevent 1 fragment. intended appearing fragment able sticky event.

when going eventbus source, stops @ :

   void invokesubscriber(subscription subscription, object event) {         try {             subscription.subscribermethod.method.invoke(subscription.subscriber, event);         } catch (invocationtargetexception e) {             handlesubscriberexception(subscription, event, e.getcause());         } catch (illegalaccessexception e) {             throw new illegalstateexception("unexpected exception", e);         }     }

edit

here scenario.

public class topevent {     string name;     public topevent(string name){         this.name = name;     } }  public class myevent extends topevent {     string extrainfo;     public myevent(string name, string extra){         super(name);         this.extrainfo = extra;      } }

here 1 fragment tx :

... eventbus.getdefault().poststickyevent(new myevent("stack","overflow"); ...

here second fragment rx

... string = eventbus.getdefault().getstickyevent(myevent.class).extrainfo; ...

here service (the 1 got strange behavior) 

public class myservice extends service {      ...      eventbus.getdefault().registersticky(this)      onevent(topevent event){        ...        ...     }  }

at end of onevent, exception thrown. if hidden behavior sticky extended event (from super) posted triggers non-sticky event of super event.

this due eventbus configuration :

eventbus.builder().throwsubscriberexception(buildconfig.debug).installdefaulteventbus();

however have difficulties understand why option interesting. in fact (almost) see exception of subscriber failed, because there exception of subscriber. hidden. why interesting ?

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
