 To compile code, the following is necessary
 
-- Appropriate [Android SDK](http://developer.android.com/sdk/index.html)
-- [CrystalX Android NDK](https://www.crystax.net/en/download) version 10.2.1 or later
+- Recent version of [Android SDK](http://developer.android.com/sdk/index.html), android-21 SDK
+  and 21.1.2 build tools (for build), android-19 SDK (for compatibility), and several other SDK
+  components
+- [CrystalX Android NDK](https://www.crystax.net/en/download) version 10.3.1
+- [Gradle build automation system](http://gradle.org/) version 2.10
 
 Example script for Ubuntu 14.04 to get all dependencies, download SDK and NDK:
 
-    sudo apt-get install -y build-essential git openjdk-7-jdk unzip
