Building on Android
===================

Pre-requesties
--------------

You need to install Android SDK, NDK  and QT with android support.

- [SDK](https://developer.android.com/studio/index.html) (choose command line tools only)  
- [NDK](https://developer.android.com/ndk/downloads/index.html)  
- [QT](https://www.qt.io/download-open-source/). Choose one for your platform for android. For example QT 5.6 under Linux would be [this file](http://download.qt.io/official_releases/qt/5.6/5.6.1-1/qt-opensource-linux-x64-android-5.6.1-1.run  )

You also need Java JDK and Ant.

QT-Creator
----------
Open QT-creator that should be installed with QT.  
Go to Settings/Anndroid and specify correct paths to SDK and NDK.
If everything is correct you will see two set avaiable:  
Android for armeabi-v7a (gcc, qt) and Android for x86 (gcc, qt).
