Android: How to programmatically access the device serial number shown in the AVD manager (API Version 8)
android, serial-number
Solution
This is the hardware serial number. To access it on
Android Q (>= SDK 29) `android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE` is required. Only system apps can require this permission. If the calling package is the device or profile owner then the `READ_PHONE_STATE` permission suffices.
Android 8 and later (>= SDK 26) use `android.os.Build.getSerial()` which requires the dangerous permission READ_PHONE_STATE. Using `android.os.Build.SERIAL` returns android.os.Build.UNKNOWN.
Android 7.1 and earlier (<= SDK 25) and earlier `android.os.Build.SERIAL` does return a valid serial.
It's unique for any device. If you are looking for possibilities on how to get/use a unique device id you should read here.
For a solution involving reflection without requiring a permission see this answer.
