cordova - Android app failing to start missing Chromium WebView

Question

I am using sencha touch with phonegap/cordova to build the android app. When my app starts up i get a white screen with something along the lines of 'MyApp, unfortunatly, has stopped.' How and where do i add the Chromium WebView?

The logs below says it missing Chromium WebView but i can't seem to figure out where that is or what to add to that.

I have found http://docs.phonegap.com/en/3.0.0/guide_platforms_android_webview.md.html but is cordovaWebView the same as Chromium? Also the doc seems to be out of date.

Answer 1

"is cordovaWebView the same as Chromium" - Yes, it should be. And the most recent version of that doc is here.

Your best bet is to build the Sencha Touch application using the Cordova CLI or Sencha Cmd as all of the WebView setup is automagically done for you.

I'm not entirely sure how to fix your existing setup, but I would definitely encourage you to use one of the two aforementioned CLI tools... it reduces the likelihood of errors like this.
