• Android NDK

Step-by-step

Download and extract the Android NDK

Download the Android NDK from the and extract it somewhere on your system (e.g. )

./sys/android-build.sh arm64-static

Meson needs a configuration file that describes the cross compilation environment (e.g. meson-android.ini). You can adjust it as necessary, but something like the following should be a good starting point:

$ CFLAGS="-static" LDFLAGS="-static" meson --default-library static --prefix=/tmp/android-dir -Dblob=true build --cross-file ./meson-android.ini

A bit of explanation about all the options:

• : it tells meson to compile just one binary with all the needed code for running radare2, rabin2, rasm2, etc. and creates symbolic links to those names. This avoids creating many statically compiled large binaries and just create one that provides all features. You will still have rabin2, rasm2, rax2, etc. but they are just symlinks to radare2.
• : it describes how to compile radare2 for Android

At this point you can copy the generated files in /tmp/android-dir to your Android device and running radare2 from it. For example:

$ cd /tmp && tar -cvf radare2-android.tar.gz android-dir
$ adb push radare2-android.tar.gz /data/local/tmp
$ adb shell
DEVICE:/ $ cd /data/local/tmp
DEVICE:/data/local/tmp $ tar xvf radare2-android.tar.gz
DEVICE:/data/local/tmp $ ./android-dir/bin/radare2
