hmmm, the problem seems to be cause because of this: https://issues.apache.org/jira/browse/CB-7827
(in cordova 4.0 there’s a bug(?) when you build, it doesnt set the android:name in AndroidManifest.xml to the name you’ve set in config.xml (it sets it to CordovaApp).
To fix this I manually changed android:name in AndroidManifest.xml to my apps name. But that’s not enough!. You’ll have to change some more stuff (see apache-link above).
