从API 26：Android 8.0 Oreo开始，不推荐使用Build.SERIAL

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.

Answer 3

As per the reference , it is deprecated since Android 8.0+ (API 26+) by the getter getSerial() . Plus you need Manifest.permission.READ_PHONE_STATE permission.
