Starting March 27, 2025, we recommend using android-latest-release instead of aosp-main to build and contribute to AOSP. For more information, see Changes to AOSP.

The adbd module manages command-line adb and IDE debugging sessions. This module
is updatable, meaning it can receive updates to functionality outside of the
normal Android release cycle.
Modularizing adbd enables faster delivery of performance improvements (those
made in previous years and new improvements yet to come), bug fixes (such as
several power-drain bugs, including adbd continuing at 100% of a CPU until the
battery depletes), and features that haven't been backported to older versions
of Android. Such improvements contribute to adbd reliability, which is critical
for automated testing where failures can force app developers and OEMs to
manually replug/restart offline devices. Reliability issues also affect factory
setup (OEMs) and board bringup (SoC vendors).
Module boundary
For Android 12 and higher, the adbd module code is
packages/modules/adbd.
For Android 11 and lower, the adbd module boundaries
are /system/core/adb and /system/bin/adbd.
The adbd module (com.android.adbd) is in
APEX format and is available for devices
running Android 11 or higher.
Module dependences
The adbd module depends on the following.
Java Debug Wire Protocol (JDWP) debugging protocol with Android runtime. adbd
dynamically links against libadbconnection_server.
Authentication with system_server. adbd dynamically links against
libadbd_auth.
Customization
The adbd module doesn't support customization.
