Build.SERIAL is deprecated as of API 26: Android 8.0 Oreo

Question

I just updated my application to API 26 and I'm trying to retrieve the serial of the device and I'm seeing that Build.SERIAL is deprecated on API 26.

What should I use instead?

Answer 1

Use Build.getSerial() as per the docs. Note that this requires the READ_PHONE_STATE permission.

Answer 2

Build.SERIAL

This field was deprecated in API level 26. Use getSerial() instead.

Note

[...] For apps targeting SDK higher than Build.VERSION_CODES.O_MR1 this field is set to UNKNOWN.
