Access getDeviceID() for a Device Owner App Android 10?

Question

I have many phones I need to register in a database with IMEI barcodes and install a company app on it to connect and track them. For this purpose I need to access the IMEI with getDeviceID(). Since Android 10, it is not as simple.

In this page, Android says if you are device owner you can access it : https://developer.android.com/training/articles/user-data-ids

I use this method to make my app a device owner app : How to make my app a device owner?

adb shell dpm set-device-owner com.package.name/.MyDeviceAdminReceiver 

When I use getDeviceId() in the app, I still have the error :

 java.lang.SecurityException: getDeviceId: The user 10180 does not meet the requirements to access device identifiers.

Why this method doesn't work ? Do you have any suggestions to the IMEI ?

Answer 1

Setting your application as device owner is not sufficient, you also need it to complete the provisioning flow. For Android up to 11 it is started by launching ACTION_PROVISION_MANAGED_DEVICE, for Android 12 you have to listen to ACTION_GET_PROVISIONING_MODE

Google provides a sample DPC.
