The JDK version 1.6.0_23 is required : https://drive.google.com/file/d/0B-vV81AxHSyfU1RESlZ2MFlveDg/view?usp=sharing
Setup the toolchain path to point to arm-eabi- tools in prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin and to the bin/ directory in the JDK. e.g. $ export PATH=$HOME/jdk1.6.0_23/bin:$HOME/rowboat-android/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin:$PATH
