Up to Android 7.1 (SDK 25)
Until Android 7.1 you will get it with:
From Android 8 (SDK 26)
On Android 8 (SDK 26) and above, this field will return
UNKNOWN and must be accessed with:
which requires the dangerous permission
android.permission.READ_PHONE_STATE .
From Android Q (SDK 29)
Since Android Q using
Build.getSerial() gets a bit more complicated by requiring:
android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE (which can only be acquired by system apps), or for the calling package to be the device or profile owner and have the READ_PHONE_STATE permission. This means most apps won't be able to uses this feature. See the Android Q announcement from Google.

Best Practice for Unique Device Identifier![]()
If you just require a unique identifier, it's best to avoid using hardware identifiers as Google continuously tries to make it harder to access them for privacy reasons. You could just generate a patrickfpatrickf
UUID.randomUUID().toString(); and save it the first time it needs to be accessed in e.g. shared preferences. Alternatively you could use ANDROID_ID which is a 8 byte long hex string unique to the device, user and (only Android 8+) app installation. For more info on that topic, see Best practices for unique identifiers.

Build.SERIAL can be empty or sometimes return a different value (proof 1, proof 2) than what you can see in your device's settings.
If you want a more complete and robust solution, I've compiled every possible solution I could found in a single gist. Here's a simplified version of it :
I try to update the gist regularly whenever I can test on a new device or Android version. Contributions are welcome too.
