here 1 of fragments (they same):

public class oneupscreen extends screenfragment { private button name; private textview c00title, c00data; //debug public string title; //debug private int counter = 0; //for logging , convenience private static final string tag = "brrt"; @override public void onresume(){ super.onresume(); eventbus.getdefault().registersticky(this); } @override public void onpause(){ eventbus.getdefault().unregister(this); super.ondestroy(); } //process bus messaging public void onevent(expeditionevent event){ log.v(tag, "oneup event received: " + event.geteventid() + " : " + event.geteventscreenvalue()); c00data = (textview) getview().findviewbyid(r.id.c00data); c00data.settext(counter); counter++; } @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { view v = inflater.inflate(r.layout.one_up_screen_layout, container, false); name = (button) v.findviewbyid(r.id.lbltitle); c00title = (textview) v.findviewbyid(r.id.c00title); c00data = (textview) v.findviewbyid(r.id.c00data); bundle bundle = this.getarguments(); //initial set of text on screen //null check name.settext((bundle.getstring("name") == null) ? "error" : bundle.getstring("name")); c00title.settext((bundle.getstring("c00title") == null) ? "error" : bundle.getstring("c00title")); title = bundle.getstring("c00title"); homecoming v; } public oneupscreen(){ } public static oneupscreen newinstance() { oneupscreen frag = new oneupscreen(); homecoming frag; } //attach config instance. @override public void setconfig(screenconfig sc){ //set info paint screen first time bundle b = new bundle(); //now have parse stuff bundle , send bundle fragment b.putstring("name", sc.getname()); b.putstring("c00title", sc.getevents().get(0).getcleanname()); b.putint("c00data", sc.getevents().get(0).geteventid()); //pass along this.setarguments(b); } @override public void update(sparsearray<string> sensordatamap) { log.v(tag, "oneup update called: " + counter); counter++; } }

the onevent method looking here. if notice in log, method invoked. but, unable nail textview within of it. holding reference textview take in oncreate() method. saw , illustration 1 time again in event processing moved that, no luck.

if take out the:

c00data.settext(counter);

then everthing works well.

what missing here?

ok, comes here later, here how solved this...

it turns out key error seeing not event related error, resource related one.

10-15 02:19:45.271: w/resourcetype(682): no bundle identifier when getting value resource number 0x00000000

i looked elsewhere on , found this:

no bundle identifier when getting value resource number

then went code , rewrote textview.settext() calls different.

old way (counter int):

c00data.settext(counter);

new way:

c00data.settext(""+counter);

that did it. whooped.
