Here is the description of the adb package in Debian:
> Description: Android Debug Bridge
>
> A versatile command line tool that lets you communicate with an
> emulator instance or connected Android-powered device.
>
> This package recommends "android-sdk-platform-tools-common" which
> contains the udev rules for Android devices. Without this package, adb
> and fastboot need to be running with root permission.
And android-tools-adb:
> Description: transitional package
>
> This is a transitional package. It can safely be removed.
The package ninja-build should be installed automatically as a meson
dependency, but some users need to install a newer meson from pip3, so
ninja must be installed explicitly.
