Getting Android Device Identifier From ADB and Android SDK

Question

I am looking for the easiest way to get a unique android device identifier from both the Android adb and the Android ADK itself.

For example, when i use the adb 'devices' command, the serial number of my connected device is outputted to the screen. I have yet to identify a method in the Android sdk to get me the same serial number.

I don't care what unique identifier is used, just something that can be easily retrieved from both the adb and android sdk. Rooting a device will not be an option.

Answer 1

You would probably want to use ANDROID_ID.

This is how you can query its value via adb shell:

settings get secure android_id

Or by querying the settings content provider:

content query --uri content://settings/secure/android_id --projection value

Answer 2

Android stores all the device related info in one or the other sqlite DB. These databases can be found in /data/data/ folder. To read these databases from adb you will need root permissions.

The android id is available in /data/data/com.android.providers.settings/databases/settings.db

So for adb use this command.

adb shell sqlite3 /data/data/com.android.providers.settings/databases/settings.db "select value from secure where name = 'android_id'"

**you must be running adb as root in adb

Answer 3

Simple as that with adb

adb devices -l
