DeDroid

Docker image to easily decompile (and recompile) Android APKs

This image contains the following tools:

• apktool
• zipalign and apksigner (Android SDK)
• dex2jar

Usage

Start the shell inside the container, mapping the APK directory to /work

docker run --rm -v PATH_TO_APK_DIR:/work -ti fopina/dedroid sh

All the tools are in the PATH (in /dedroid directory), so you just go ahead and do apktool d APK or d2j-dex2jar.sh APK

There's also an helper script:

$ docker run --rm fopina/dedroid helper > /usr/local/bin/dedroid
$ chmod a+x /usr/local/bin/dedroid
$ dedroid
Usage: dedroid d APK_FILE OUTPUT_DIR
       dedroid b INPUT_DIR APK_FILE
       dedroid j APK_FILE JAR_FILE

"d" will unpack the APK to OUTPUT_DIR and decode .dex to smali
"b" will rebuild APK from INPUT_DIR, zipalign it and sign it with new self-signed certificate
"j" will run dex2jar on APK_FILE

$ dedroid d some.test.apk tempdir
.... make changes in the smali files inside tempdir .....
$ dedroid b tempdir new.some.test.apk
.... ready to be installed in device/emulator!
