Http Server for Android is an open source software under MIT licese.
Thanks to libevent, RapidJSON, android-folder-picker-library and android-cmake.
NDK is used to develop this software, and for convenience I choose C++ 11 standard to program. So you should choose NDK support C++ 11.
From Google Play Store or download Android APK
If you encounter an bug, You can fire an issue at GitHub. I will fix it as soon as possible.
