we have a major issue. We have a angular app which is wrapped in cordova container. We generate a debug and release APK version in Android-Studio.

When we deploy the debug APK version on a mobile the app is working fine. When we deploy the release signed APK version on a mobile the app is working NOT fine. We are using in our app a own developed angular libary which is handling the http request. We have a problem that our libary which doing the http connection not response.

Is there any configuration in cordova/android studio/gradle which could cause this issue on the release apk version, that maybe not allow this libary not do any http requests ?

Any help would highly appricated.

we found the problem ! In our own lib we have been using a HTTP-Request with no timeout defined. The URL we called in the Request, was not existing at this point of the project. On the mobile in the Debug.apk this did not matter but in der Release.apk on the mobile it matters and there was just no responses at all. We added to the http-Request a timeout and it worked.

We still not know why the timeout did not matter on the Debug.apk and but on the Release.apk

Also, there was a certificate error on the HTTPS-Certificate on the server which need to be reconfigured. Android is very strict on the the certificate setup which the debug.apk doesn't do. The complete certificate chain need to be provided by the provided certificate. If the certificate not provide all necessary information on the request than the release APK version will failure answered.

I hope it helps anyone.
