android - In Child Activity, Fragment is recreated automatically - AppCompatViewInflater app:theme is now deprecated -

-

from mainactivity, start childactivity (which extends appcompatactivity) intent. purpose of child activity display fragments (welcome text user can fill edittext enter information).

                intent myintent = new intent(this, createuseractivity.class);                 startactivityforresult(myintent, mainactivity.request_create_profile);

after few seconds, in activity, restarted...the view reloaded.

so annoying, because if in second fragment. activity restart , first one. user have restard work.

i've got following message in logcat when activity recreated :

08-07 20:45:37.673    8010-8010/com.xxxxx.xxxxxi/appcompatviewinflater﹕ app:theme deprecated. please move using android:theme instead.

any idea ?

childactivity code (relevant part): 

 @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         intent intent = getintent();         setcontentview(r.layout.activity_main);     // load layout         createtoolbar();         setupprofile();     }       @override     public boolean onoptionsitemselected(menuitem item) {         // handle action bar item clicks here. action bar         // automatically handle clicks on home/up button, long         // specify parent activity in androidmanifest.xml.         int id = item.getitemid();         if (id == r.id.action_settings) {             return true;         }         return super.onoptionsitemselected(item);     }      @override     public void onbackpressed(){         //super.onbackpressed();         this.movetasktoback(true);     }     private boolean createtoolbar() {          toolbar mtoolbar = (toolbar) findviewbyid(r.id.toolbar);         setsupportactionbar(mtoolbar);         mtoolbar.setnavigationicon(r.drawable.ic_drawer_white); //todo : isn't taking account...default icon not replaced - todo : understand why ???         mtoolbar.settitle("xxxxxx toolbar");         mtoolbar.setlogo(r.drawable.ic_menubar_v3);         mtoolbar.setlogodescription(getresources().getstring(r.string.description));         mtoolbar.setnavigationcontentdescription(getresources().getstring(r.string.navigation_icon_description));         getsupportactionbar().setdisplayhomeasupenabled(true);         getsupportactionbar().sethomebuttonenabled(true);         getsupportactionbar().setdisplayshowtitleenabled(true);         getsupportactionbar().settitle(null);          return true;     }           //if first time app used, user needs create profile process         private boolean setupprofile() {              drawerlayout mdrawerlayout = (drawerlayout) findviewbyid(r.id.drawer_layout);         setrequestedorientation(activityinfo.screen_orientation_nosensor);                            //disable orientation changes             mdrawerlayout.setdrawerlockmode(drawerlayout.lock_mode_locked_closed);                      //disable drawer         welcomefragment mywelcomefragment = welcomefragment.newinstance();         disableenablecontrols(false, (viewgroup) findviewbyid(r.id.root_linear_layout));         getsupportfragmentmanager().begintransaction()                 .replace(r.id.fragment_container3, mywelcomefragment).commit();         return true;

i have been having issue well, , have found because of custom support toolbar you're using. if not necessary, try stick conventional overflow menu

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
