Step A: Update the system and install all necessary packages
1 2 3 4 5 6 7 | sudo dpkg --add-architecture i386;sudo apt-get update;sudo apt-get upgrade -y;sudo apt-get install git openjdk-8-jdk dh-autoreconf ant libncurses5:i386 libstdc++6:i386 zlib1g:i386 -y;cd ~/;mkdir Android;cd Android; |
Step B: Download the Android SDK and install all required packages
The following download link we got it from this page https://developer.android.com/studio/
1 2 3 4 5 6 | wget https://dl.google.com/android/android-sdk_r24.4.1-linux.tgz;tar -xf android-sdk_r24.4.1-linux.tgz;cd android-sdk-linux/tools;#To list all available packages, including the obsolete extra-android-support#./android list sdk --all –extended;./android update sdk --no-ui --all --filter extra-android-support,tools,platform-tools,build-tools-19.1.0,android-19; |
You will get a prompt for a license agreement, you need to type Y to proceed
November 20, 2015 Do you accept the license 'android-sdk-license-c81a61d9' [y/n]: y
1 2 | cd ../..;export ANDROID_HOME=`pwd`/android-sdk-linux; |
Step C: Once the installation is complete, we need to install the Android NDK.
The following link we got it from https://developer.android.com/ndk/downloads/
1 2 3 4 5 6 7 | wget https://dl.google.com/android/repository/android-ndk-r13b-linux-x86_64.zip;unzip -q android-ndk-r13b-linux-x86_64.zip;export NDK_DIR=`pwd`/android-ndk-r13b;#If we do not update the PATH we will get the following error: ../libtool: line 1719: arm-linux-androideabi-ranlib: command not foundPATH=$PATH:`pwd`/android-ndk-r13b/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin;mkdir Projects;cd Projects; |
Step D: Afterwards, we can download SnoopSnitch and all of the git submodules of it using the following command.
1 | git clone --recursive https://opensource.srlabs.de/git/snoopsnitch.git; |
Step E: Then we need to compile two separate parts of the project.
We will start by compiling contrib/ projects, that are the supplementary projects needed for SnoopSnitch to get data.
1 2 3 | cd snoopsnitch/contrib/;./compile.sh -t android -u;cd ..; |
Step F: Finally, we can proceed to compile the android project of SnoopSnitch.
1 | cd ./SnoopSnitch; |
We need to update Application.mk and add APP_ABI := armeabi to it.
We do this to make sure that we compile diag-helper.c only for armeabi as the rest of the packages will be available only on that architecture.
If we do not do this and we have a processor that supports armeabi-v7a (or different), then it will only install diag-helper.so and it will ignore the rest. Which will of course cause the application to fail.
1 2 3 | echo "APP_ABI := armeabi" >> jni/Application.mk;ant debug;~/Android/android-sdk-linux/platform-tools/adb start-server |
Once the compilation is complete, we can upload our apk to a device using the following commands:
1 2 3 4 5 6 | #First we make sure that the adb server is running$ANDROID_HOME/platform-tools/adb start-server;#Then we check that our device is visible to the adb$ANDROID_HOME/platform-tools/adb devices;#Finally, we install the application to the device.$ANDROID_HOME/platform-tools/adb install bin/SnoopSnitch-debug.apk; |
This guide was tested on freshly installed Ubuntu 16.10 64bit.
