Please remember that configuring the proxy doesn''t mean that all your applications will automatically start to using these settings! This is due to a not easy understandable API for developers. If you are interested in a deeper analysis of this issue, you can find a detailed explanation of the problem and leave your feedbacks/comments on our website: http://shouldit.be/, or just reach us at: email@example.com.
The project offers also an open source module called Android Proxy Library (APL) that provides to the developers an easy way to access and use the proxy settings in every Android application. So, if you want the Proxy support in your favourite applications, start request this feature to their developers!
