Cordova changed its webview from org.apache.cordova.CordovaWebView to org.apache.cordova.engine.SystemWebView

[Pas]

Dear all

If I query with query("*") my current cordova project then I get

"class"=>"com.android.internal.policy.impl.PhoneWindow$DecorView", "rect"=>{"center_y"=>480, "center_x"=>270, "height"=>960, "y"=>0, "width"=>540, "x"=>0}, "tag"=>nil, "description"=>"com.android.internal.policy.impl.PhoneWindow$DecorView{41e52b58 V.E..... R....... 0,0-540,960}"}, {"id"=>nil, "enabled"=>true, "contentDescription"=>nil, "class"=>"android.widget.LinearLayout", "rect"=>{"center_y"=>480, "center_x"=>270, "height"=>960, "y"=>0, "width"=>540, "x"=>0}, "tag"=>nil, "description"=>"android.widget.LinearLayout{41e53418 V.E..... ........ 0,0-540,960}"}, {"id"=>"content", "enabled"=>true, "contentDescription"=>nil, "class"=>"android.widget.FrameLayout", "rect"=>{"center_y"=>499, "center_x"=>270, "height"=>922, "y"=>38, "width"=>540, "x"=>0}, "tag"=>nil, "description"=>"android.widget.FrameLayout{41e59690 V.E..... ........ 0,38-540,960 #1020002 android:id/content}"}, {"id"=>nil, "enabled"=>true, "contentDescription"=>nil, "class"=>"org.apache.cordova.engine.SystemWebView", "rect"=>{"center_y"=>499, "center_x"=>270, "height"=>922, "y"=>38, "width"=>540, "x"=>0}, "tag"=>nil, "description"=>"org.apache.cordova.engine.SystemWebView{41d52650 VFEDH.CL .F...... 0,0-540,922 #64}"}]

This causes me great problems because I can not query the webview anymore. I tried to query the SystemWebView like this

query("SystemWebView css:'*'") but i get the following error.

map SystemWebView css:'*', query failed because: sh.calaba.instrumentationbackend.actions.webview.CalabashChromeClient cannot be cast to org.apache.cordova.engine.SystemWebChromeClient
       (RuntimeError)
      ./features/step_definitions/calabash_steps.rb:11:in `/^I am on the main page$/'
      features/my_first.feature:4:in `Then I am on the main page'

Is there a quick way around this.

Cheers
Pascal

Please run adb logcat and post the full stack trace.

Here is the full stack track when query("cordovaWebView css:'*'"). I don't get an error for this but always an empty result.

This is the answer I received from SO:

"Unless you install the crosswalk plugin, the webview is still a CordovaWebView, systemWebview will return the CordovaWebView if you use it's getCordovaWebView() method"
http://stackoverflow.com/questions/31696314/make-cordova-use-old-cordovawebview-instead-of-systemwebview?noredirect=1#comment51337065_31696314

Doesn't help me too much because I'm not really familiar with the internals of your framework. However maybe it helps you.

[tobias....@xamarin.com]

That is not an error. Please post the stacktrace from the right query, e.g. query("SystemWebView css:'*'")

I solved this:

In sh.calaba.instrumentationbackend.sh.calaba.instrumentationbackend.actions.webview.CalabashChromeClient line 89 I added another case for isCordovaWebView and build the gem on my own.

boolean isCordovaWebView = superClassEquals(webViewClass, "org.apache.cordova.CordovaWebView")
                || superClassEquals(webViewClass, "org.apache.cordova.engine.SystemWebView");

I don't know if the change made by Cordova has other implications for your testframe work but it is now possible to query the webview with:

query("systemWebView css:'*'")

Hi Pascal,

I am working on Apache Cordova team at Microsoft. Our team is interested in understanding your experiences with embedded Cordova web views. Would you be able to fill in this quick contact info survey http://www.instant.ly/s/WGx9L so that we can get in touch with you?

Kind regards,
