Compilation Steps

1. Download the Android NDK from https://developer.android.com/ndk/downloads/. Extract the zip to a suitable location.

   $ wget https://dl.google.com/android/repository/android-ndk-r18b-linux-x86_64.zip
   

2. Clone the repository

   $ git clone https://github.com/extremecoders-re/tcpdump-android-builds.git
   $ cd tcpdump-android-builds
   

3. For compiling, set NDK to the location of the android sdk directory and run the corresponding build script.

   $ NDK=/home/ubuntu/workspace/android-ndk-rxxx/ ./build_x86.sh
   $ NDK=/home/ubuntu/workspace/android-ndk-rxxx/ ./build_x86_64.sh
   $ NDK=/home/ubuntu/workspace/android-ndk-rxxx/ ./build_arm.sh
   $ NDK=/home/ubuntu/workspace/android-ndk-rxxx/ ./build_arm64.sh
   

4. Compiled binaries will be located in the corresponding tcpdumpbuild directory.

Compile libpcap for multiple targets and API versions

You can use the build_libpcap_all.sh script to run the scripts mentioned above for multiple targets and Android API versions. This can be useful if you need to buid libpcap for multiple targets / API versions.

1. Run the script build_libpcap_all.sh and set NDK to the location of the android sdk directory.

2. You can also specify the following parameters:

• OUTPUT_DIR for the output directory. The default is libpcap_all_targets.
• TARGETS one or more targets from this list: arm arm64 x86 x86_64. The default is all of them.
• API_MIN min API version. The default is 21.
• API_MAX max API version. The default is 30.

3. Examples:

   $ NDK=/home/ubuntu/workspace/android-ndk-rxxx/ ./build_libpcap_all.sh
   $ NDK=/home/ubuntu/workspace/android-ndk-rxxx/ OUTPUT_DIR=my_dir ./build_libpcap_all.sh
   $ NDK=/home/ubuntu/workspace/android-ndk-rxxx/ TARGETS="x86 x86_64" ./build_libpcap_all.sh
   $ NDK=/home/ubuntu/workspace/android-ndk-rxxx/ API_MIN=21 API_MAX=30 /build_libpcap_all.sh
