@illnino You need to

1. Download android-sdk command-line tools
2. Install the Android SDK Platform Tools, Android SDK Build Tools by running the command ./android from within extracted ZIP archive
3. Set the $PATH environment variable to point to the build-tools, platform-tools & tools directory of the Android SDK.
4. Confirm step 3 by running the command which android, which aapt etc. to make sure they all point to the directory you just set.
5. You would also need to install apktool, if not already installed. Read the guide here
