Cordova app no showing anything (log says error in ecmascript.js:279)


I followed angular2-meteor tutorial. I tried to debug the app in the simulator and in a smartphone (meteor run android/android-device --verbose). In both cases, the app loads the meteor splash screen. But, after that, only an empty white screen appears.

The only hint I see is within the meteor sun android/android-device logs which state in both cases the following:

I20160603-12:17:11.092(2)? D/MeteorWebApp( 2249): Downloaded asset manifest for version: 64e637af5e28546f390d6025d2c3e5661c275905

I20160603-12:17:13.070(2) (android:http://localhost:12264/packages/ecmascript-runtime.js:279) Uncaught TypeError: Cannot redefine property: onreadystatechange

I do not know how to continue, how to obtain more information about the error or where is the point where the app failed.

Please, ask me for anything to show. There are so many things that I prefer to post more info as requested to not flooding the post.
Thank you in advance,
