[Bug] [Android] Accept-Charset header

[gasperinn]

Overview of the Issue

I am having problems with sending requests to Authenticate Server from an Ionic 3 app as the request is being denied (403) because "Accept-Charset" header is being set as "UTF-8". As described here, this header should not be used anymore.

Operating System

Android only

Suggest a Fix

In class CordovaHttpBase, in function prepareRequest the line 136 where the header "Accept-Charset" is set should be deleted :

request.acceptCharset("UTF-8");
