android - Why pressing back button inside of cordova WebView closes app? -


given 2 initialized , added in backstack fragments (one of them see on screen). each fragment has cordovawebview view. in 1 web view have loaded "www.google.com" in "www.bing.com". now, if press button - awaiting, fragment "www.bing.com" poped stack , see google site on device screen. instead of this, app exits (for short time can see google.com, app completly exits)

small part of activity:

cordova.getactivity().getfragmentmanager() .begintransaction() .replace(r.id.fragment_container, webviewfragmentgoogle) .addtobackstack(null) .commit();   cordova.getactivity().getfragmentmanager() .begintransaction() .add(r.id.fragment_container, webviewfragmentbing) .addtobackstack(null) .commit();

fragment:

public class webviewfragment extends fragment {      private string murl = "file:///android_asset/www/main.html";     private cordovawebview mwebview;      @override     public view oncreateview(layoutinflater inflater, viewgroup container,             bundle savedinstancestate) {            view view = inflater.inflate(r.layout.webview_fragment,container, false);          if (view != null)             mwebview = (cordovawebview)view;            bundle bundle=getarguments();          string iframeurl = bundle.getstring("iframeurl");           if (!murl.isempty())         {             mwebview.loadurl(iframeurl);          }            return view;     }       public void gotourl(string url) {          mwebview.loadurl(url);      }        @override     public void onresume() {         super.onresume();          if (mwebview!= null) {             mwebview.handleresume(true, false);         }      }       @override     public void onpause() {         if (mwebview != null)         {             mwebview.handlepause(true);         }           super.onpause();     }       @override     public void ondestroy() {         if (mwebview != null)         {             mwebview.handlepause(true);             mwebview.handledestroy();         }            super.ondestroy();      }      }

this happens because of cordovawebview.onkeyup() logic - intercepts key strokes , hooks actions on them: in case action is:

this.cordova.getactivity().finish();

personally find killing activity bit intrusive, in case, when cannot configure in way. please check cordovawebview messes onbackpressed method in android details.

ruby on rails - In a controller spec, how to find a specific tag in the generated view? -

i know integration tests preferred need ran in controller test, i'm testing gem injecting html code in view, xhr can't run in feature spec (if can, please explain me how :) ) so rspec controller tests can assert selector present (with capybara) : response.body.should have_selector('#foobar') has_selector? call all method capybara find selector. what want last child of body , assert id in particular. afaik it's not possible have_selector. what : all('body:first-child').first.id.should == '#foobar' however, capybara dsl, defined (more or less): def all(*args) page.all(*args) end and page empty unless use visit it's integrations specs. how can use capybara all method inside rspec controller test ? i can't test right after googling seems trick def page capybara::node::simple.new(response.body) end source
