n2n/android/README.md

Building n2n on Android

• Install jdk.

• Generate app keystore by the command keytool -genkey -alias Hin2n -keystore Hin2n.jks. And remember these two passwords:

  keytool -genkey -dname "CN=Unknown,O=Unknown,C=Unknown" -keystore Hin2n.jks -keysize 1024 -alias Hin2nalias -validity 14000 -keypass yourpassword -storepass yourpassword
  

• Move Hin2n.jks to android/Hin2n/app directory. We will use this file to sign the application.

• In the file app/build.gradle replace yourpassword with the password used to generate the keystore.

• Download Android tools from https://developer.android.com/, and unzip it.

• Install Android development environment.

  echo y | ./tools/bin/sdkmanager tools
  echo y | ./tools/bin/sdkmanager platform-tools
  echo y | ./tools/bin/sdkmanager ndk-bundle
  echo y | ./tools/bin/sdkmanager "cmake;3.6.4111459"
  echo y | ./tools/bin/sdkmanager "lldb;3.1"
  

• Set environment variables.

  export ANDROID_HOME=YOUE_ANDROID_DEV_HOME
  export ANDROID_NDK_HOME=\$ANDROID_HOME/ndk-bundle
  export HIN2N_KSTOREPWD=YOUR_APP_KEYSTORE_PASSWORD
  export HIN2N_KEYPWD=YOUR_APP_KEY_PASSWORD
  

• Compile the app.

  cd android/Hin2n
  ./gradlew assemble
  

• You will get the app in android/Hin2n/app/build/outputs/apk/ directory.
