To ensure minimal support for managed profiles, OEM devices must contain the following essential elements:
- Profile owner (as described in Ensuring Compatibility with Managed Profiles)
- Device owner
For a complete list of requirements, see Implementing Device Management. To test device management features, device owners can use the TestDPC application described below.
Set up device owner for testing
Use the following instructions to set up a device owner testing environment.
- Factory reset the target device.
- Ensure the device does not contain any user accounts (e.g. those used to log into online services). To verify, check Settings > Accounts.
- Set up the testing application using one of the following methods:
- Set the TestDPC app as the device owner using the following command:
adb shell dpm set-device-owner "com.afwsamples.testdpc/.DeviceAdminReceiver"
- Go through device owner setup on the device (encrypt, select Wi-Fi, etc.).
Verify device owner setup
To verify the device owner was correctly setup, go to Settings > Security > Device Administrators and confirm TestDPC is in the list. Verify it cannot be disabled (this signifies it is a device owner).
Automated provisioning testing
To automate the testing of enterprise provisioning processes, use the Android Enterprise Test Harness. For details, see Testing Device Provisioning.
Bug reports and logs
As of Android 7.0, device owner Device Policy Client (DPCs) can get bug reports and view logs for enterprise processes on a managed device.
To trigger a bug report (i.e., the equivalent data collected by
adb bugreport containing
dumpsys, dumpstate, and
logcat data), use
the bug report is collected, the user is prompted to give consent to send the
bug report data. Results are received by
details on bug report contents, see
Reading Bug Reports.
In addition, device owner DPCs can also collect logs related to actions a
user has taken on a managed device. Enterprise process logging is required for
all devices that report device_admin and enabled by a new log security buffer
readable only by the system server (i.e.,
$ adb logcat -b security
cannot read the buffer). ActivityManager service and Keyguard components log the
following events to the security buffer:
- Application processes starting
- Keyguard actions (e.g., unlock failure and success)
adbcommands issued to the device
To optionally retain logs across reboots (not cold boot) and make these logs
available to device owner DPCs, a device must have a kernel with
pmsg enabled, and DRAM powered and
refreshed through all stages of reboot to avoid corruption to the logs retained
in memory. To enable support, use the
config_supportPreRebootSecurityLogs setting in
