The value is overridable via PRODUCT_DEFAULT_PROPERTY_OVERRIDES. It defaults to 1 on -user builds, and 0 for other build variants. Although ro.adb.secure is a runtime property, its value is set at build time (written into /fault).

adbd is compiled with ALLOW_ADBD_NO_AUTH (only on debuggable builds).Р”В«oth of the two conditions need to be satisfied.

Option 2: Allow adbd to connect without authentication.

Note that this mechanism applies to both of normal boot and recovery modes. user builds filter out PRODUCT_ADB_KEYS, so no /adb_keys will be included there. $ export ADB_VENDOR_KEYS=/path/to/adb/private/key When starting the host-side adbd, make sure the filename (or the directory) of the matching private key has been added to $ADB_VENDOR_KEYS. The public key, defined via PRODUCT_ADB_KEYS, will be copied to /adb_keys.

Option 1 (Recommended): Authorize a host device with adb vendor keys.Р”Р‡or debuggable builds, an RSA keypair can be used to authorize a host device that has the private key.

We can use one of the following options instead. Recovery image doesnРІР‚Вt honor the USB debugging toggle and the authorizations added under normal boot (because such authorization data stays in /data, which recovery doesnРІР‚в„ўt mount), nor does it support authorizing a host device under recovery. adb devices shows the device, but in unauthorized state. the one above) is no-op when using configfs. See the example configuration for Pixel 2 devices. If device is using configfs, check if configfs has been properly set up in init rc scripts. Write /sys/class/android_usb/android0/enable 1 # Always start adbd on userdebug and eng builds Write /sys/class/android_usb/android0/enable 0

If adbd service has been started but device not shown under adb devices, use lsusb(8) (on host) to check if the device is visible to the host.Р”В«ootable/recovery/etc/init.rc disables Android USB gadget (via sysfs) as part of the fs action trigger, and will only re-enable it in debuggable builds (the on property rule will always run after on fs).

The best way to confirm a running adbd is by checking the serial output, which shows a service start log as below.

This behavior is controlled by the recovery specific /init.rc, whose source code is at bootable/recovery/etc/init.rc. init starts adbd service automatically only in debuggable builds. $ adb devicesР”В«y default, adbd is always included into recovery image, as /system/bin/adbd. Troubleshooting adb devices doesn't show the device. Since Android Q, adb shell no longer requires manually mounting /system from recovery menu. $ adb devicesР”Р„lthough /system/bin/adbd is built from the same code base as the one in the normal boot, only a subset of adb commands are meaningful under recovery, such as adb root, adb shell, adb push, adb pull etc. A device should be listed under adb devices, either in recovery or sideload state. eng or -userdebug build variants, or ro.debuggable=1 in /fault), adbd service is enabled and started by default, which allows adb communication.
