Android Unbound DNS

Goal is to get Unbound DNS fully working with UI to configure it and system integration (replacing system DNS)

Step-By-Step Guide:

Compile Unbound DNS for Android:

• Android NDK r12
• Set environment variables according to your local paths
  • required vars are LOCAL_ANDROID_NDK_HOME and LOCAL_ANDROID_NDK_HOST_PLATFORM, see _setenv_android.bash file for reference
  • optional var _NO_CHECK_SIGNATURE, set to non-zero value to skip GPG signatures checking
• Download Unbound and libraries into fetched repository
  • ./download.sh
• Run cleanup (will remove old folders and unpack original archives)
  • ./cleanup.sh
• Launch the build script
  • ./build.sh
• Collect all libraries and binaries using packaging script
  • ./package.sh
• Final compiled binaries and libraries are put within "package" directory in build root

Compile Android application:

• Move to Android directory
  • cd Android
• Check that package.zip is in place
  • ls -lsa app/src/main/assets/package.zip
• Compile android app using Gradle
  • ./gradlew clean assemble -q -S
  • ./gradlew check -q -S
• Install Android application to connected device
  • ./gradlew installDebug

Running Unbound DNS standalone from ADB SHELL:

• Upload the package to android device

• adb push package.zip /data/local/tmp/

• Get shell

• adb shell

• Get to package location

• cd /data/local/tmp/

• Expand zip archive

• unzip package.zip
• cd /data/local/tmp/package/bin

• Set Environment PATH variable

• ./env.sh

• Setup remote control certificate

• unbound-control-setup

• Setup DNSSEC root key

• unbound-anchor -h

• If you've edited unbound.conf, check it's correct

• unbound-checkconf

• Run applications from bin folder

• unbound -v -c unbound.conf

• Check if the server is running and unbound-control set up correctly

• unbound-control status

• Check if the DNSSEC verification works correctly

• unbound-host -d -C unbound.conf google.com
