NFD on Android

Prerequisites

To compile code, the following is necessary

• Recent version of Android SDK, android-21 SDK and 21.1.2 build tools (for build), android-19 SDK (for compatibility), and several other SDK components
• CrystalX Android NDK version 10.3.1
• Gradle build automation system version 2.10

Example script for Ubuntu 14.04 to get all dependencies, download SDK and NDK:

CRYSTAX_NDK_VERSION=10.3.1
GRADLE_VERSION=2.10
SDK_VERSION=24.4.1

BUILD_TOOLS_VERSION=21.1.2
COMPILE_SDK_VERSION=21

sudo apt-get install -y build-essential git openjdk-7-jdk unzip

# SDK binaries need i386 libraries
sudo dpkg --add-architecture i386;
sudo apt-get update -qq; sudo apt-get install -y libc6:i386 libncurses5:i386 libstdc++6:i386 zlib1g:i386

wget https://www.crystax.net/download/crystax-ndk-$CRYSTAX_NDK_VERSION-linux-x86_64.tar.xz
tar xf crystax-ndk-$CRYSTAX_NDK_VERSION-linux-x86_64.tar.xz
rm crystax-ndk-$CRYSTAX_NDK_VERSION-linux-x86_64.tar.xz

wget http://dl.google.com/android/android-sdk_r$SDK_VERSION-linux.tgz
tar zxf android-sdk_r$SDK_VERSION-linux.tgz
rm android-sdk_r$SDK_VERSION-linux.tgz

export ANDROID_HOME=`pwd`/android-sdk-linux
export PATH=${PATH}:${ANDROID_HOME}/tools:${ANDROID_HOME}/platform-tools

echo "y" | android update sdk --filter platform-tools,build-tools-$BUILD_TOOLS_VERSION,android-$COMPILE_SDK_VERSION,extra-android-support,extra-android-m2repository,extra-google-m2repository --no-ui --all --force
echo "y" | android update sdk --filter "android-19" --no-ui --all --force

wget https://services.gradle.org/distributions/gradle-$GRADLE_VERSION-bin.zip
unzip gradle-$GRADLE_VERSION-bin.zip
rm gradle-$GRADLE_VERSION-bin.zip
export PATH=$PATH:`pwd`/gradle-$GRADLE_VERSION/bin

Building

git clone --recursive http://gerrit.named-data.net/NFD-android
echo sdk.dir=`pwd`/android-sdk-linux > NFD-android/local.properties
echo ndk.dir=`pwd`/crystax-ndk-10.3.1 >> NFD-android/local.properties
cd NFD-android

../gradle/gradle-2.10/bin/gradle assembleRelease

Setting up environment using Vagrant

The development setup can be set up with Vagrant and scripts provided in .vagrant/ folder. After vagrant command-line is installed, the following will create VM environment and fetch all necessary dependencies:

cd .vagrant
vagrant up
vagrant ssh

Refer to vagrant documentation for more information.
