Hi Sergey, I appreciate your interest in VTS.

To test it, a native application has to be written. It should be similar to the ios app, but smaller. It should start with the default mapconfig (our intergeo 2017 url), and has to respond to basic gestures (pan, rotate, zoom).

My plan was to use the android NDK. It should be possible to prepare complete project for building the VTS with cmake - with minimum required changes to the generated project afterwards (such as setting signing certificates?). Furthermore, it should be possible to build the android app on windows, mac and linux.

I have looked at your fork and I assume that the only problematic libraries are boost and curl. Is that correct? The curl library should be completely omitted from the android build and native content fetcher should be used instead. This should completely eliminate any issues with openssl. I don't know what to do about boost yet. I had not looked into it.

I hope this covers basic requirements and answers your question.

Best, TM
