Thanks for this info… Thats the trouble I had… My app would run fine in debug mode but access would fail with release version.
Hi! Although this thread is somehow old, I’m experiencing the same issue… but solved it following this post: http://stackoverflow.com/questions/32148646/in-cordova-on-android-app-requests-with-https-fail-but-same-request-using-http-s
Quoting what the post says:
Open “\cordova\platforms\android\CordovaLib\src\org\apache\cordova\ CordovaWebViewClient.java”. In ‘onReceivedSslError’ method, comment the else part and add handler.proceed() instead.
The only difference is that I did that changed in the file named platforms/android/CordovaLib/src/org/apache/cordova/engine/SystemWebViewClient.java
Be ware of this change that you are ignoring SSL errors and could be a vulnerability issue of your app, but at least in my case I have things controlled - or at least I think I have 
having the same kind of problem with me too
but i found the fix
Okay, Thank you!
