android - Fragment with googlemaps: inflater.inflate crashes when destoried and recreated in ViewPager? -
i using actionbarsherlock , sherlockfragmentactivity.
i have 3 fragments , in tab + viewpager layout.
the 3rd fragment problem. fragment displays location on google maps.
from notice, viewpager, create new page, , if scroll away page more 1 page, destory page.
so fine first time around, go page 2, , calls create on page3 googlemaps.
however, problem if go page 1 (destories page 3 googlemaps). if go page 2 (tries create page3), page3's inflater.inflate die , i'll error, first choreographer class.
so question is, why inflater.inflate failing, , proper way program tab viewpager fragments this.???
code here (on create of main activity):
@override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); getwindow().setflags(layoutparams.flag_fullscreen, layoutparams.flag_fullscreen); setcontentview(r.layout.main_activity); mtabhost = (tabhost)findviewbyid(android.r.id.tabhost); mtabhost.setup(); mviewpager = (viewpager)findviewbyid(r.id.pager); mtabsadapter = new tabsadapter(this, mtabhost, mviewpager); mtabsadapter.addtab(mtabhost.newtabspec("driverinfo").setindicator("driver info"), driverinfo.class, null); mtabsadapter.addtab(mtabhost.newtabspec("alarmsystem").setindicator("alarm system"), alarmsetting.class, null); mtabsadapter.addtab(mtabhost.newtabspec("vehiclelocation").setindicator("location"), vehiclelocation.class, null); if (savedinstancestate != null) { mtabhost.setcurrenttabbytag(savedinstancestate.getstring("tab")); } } @override protected void onsaveinstancestate(bundle outstate) { super.onsaveinstancestate(outstate); outstate.putstring("tab", mtabhost.getcurrenttabtag()); } code: location fragment:
public class vehiclelocation extends fragment implements serverrequestinterface { private googlemap mmap; private progressdialog mprogressdialog; @override public void oncreate(bundle savedinstancestate) { try { super.oncreate(savedinstancestate); setupprogressdialog(); } catch (exception ex) { system.out.println(ex.tostring()); } } @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { //where keeps die-ing ---------------------------------- view view = inflater.inflate(r.layout.vehicle_location, container, false); setupmapifneeded(); return view; } error log:
