[ANDROID][volley] Handle UnsupportedEncodingException in invokeAPI (#…

* [ANDROID][volley] Handle UnsupportedEncodingException in invokeAPI (Issue #6432)
The constructor of StringEntity can throw UnsupportedEncodingException, which is not catch nor thrown by createRequest method.
Therefore the build of android client fails with:

ApiInvoker.java:448: error: unreported exception UnsupportedEncodingException; must be caught or declared to be thrown

This commit adds a try ... catch on UnsupportedEncodingException in invokeAPI methods and declare this exception to be thrown in createRequest
