How to obtain the android_id of a device? [duplicate]

Answer 1

adb shell sqlite3 /data/data/com.android.providers.settings/databases/settings.db "SELECT value FROM secure WHERE name='android_id'"

The android id is changeable with a rooted phone... Insert a android id with:

adb shell sqlite3 /data/data/com.android.providers.settings/databases/settings.db "UPDATE secure SET value='IDHERE' WHERE name='android_id'"
