FAQ

Already some accounts on the device

java.lang.IllegalStateException: Not allowed to set the device owner because there are already some accounts on the device

Solutions: freeze the accounts' holder apps, or delete those accounts.

Already several users on the device

java.lang.IllegalStateException: Not allowed to set the device owner because there are already several users on the device

Solution: Delete secondary users, including work profile, private space and app cloning.

Device owner is already set

java.lang.IllegalStateException: Trying to set the device owner (com.bintianqi.owndroid/.Receiver), but device owner (xxx) is already set.

Only one device owner can exist on a device. Please deactivate the existing device owner first.

MIUI & HyperOS

java.lang.SecurityException: Neither user 2000 nor current process has android.permission.MANAGE_DEVICE_ADMINS.

Solutions:

• Enable USB debugging (Security setting) in developer options.
• Or execute activating command in root shell.

ColorOS

java.lang.IllegalStateException: Unexpected @ProvisioningPreCondition

Solution: Use OwnDroid testkey version

The testkey and signed versions differ only in their signatures. There is no functional difference between them.

Samsung

user limit reached

Samsung restricts Android's multiple users feature. There is currently no solution.

Create work profile / user

On most devices, creating work profile is not allowed by the system when the device owner exist. Because the system add no_add_managed_profile user restriction when a device owner is set. Device owner can't modify user restrictions set by the system, but if your device is rooted, you can disable this restriction by executing the following commands in adb shell. Note: the device owner and the work profile owner can't be the same app, or the device owner will lose its privilege during reboot.

pm set-user-restriction no_add_user 0
pm set-user-restriction no_add_managed_profile 0
pm set-user-restriction no_add_private_profile 0
pm set-user-restriction no_add_clone_profile 0

You should bypass the restrictions at your own risk. It may cause unexpected behavior, for example, the system may delete the user you created silently during reboot.

Some systems disable the feature of adding users in Android settings once a device owner is set. You have to create users in OwnDroid. Or if you have root, run the above command in adb shell to remove that restriction.
