如何查看Android App是否为设备所有者？

Question

I am executing one test case using robot framework where I have to install an app and make it as device owner and then check if the same app has become a device owner or not. I have searched though Stack Overflow and other search engine results but there, they have mentioned on how to make an app as device owner but not the way how to check if an app is a device owner.

I have used following command to make my app as device owner:

adb shell dpm set-device-owner com.myapp.package/.main.receiver.DeviceAdminReceiver

Now, I wanted to validate whether it is a device owner or now using ADB command.

Answer 1

adb shell dumpsys device_policy

This command will give you a bunch of policies including the device owner (it's the first policy) with the package name and the corresponding receiver.

To make it easier to check it use adb shell dumpsys device_policy | grep "admin" adb shell dumpsys device_policy | grep "admin"

Answer 2

adb shell getprop ro.device_owner

如果启用了设备所有者模式，则返回true 。

Answer 3

you need to interrogate the system and return A LOT of data. This is not feasible, however as a tip for others, you can use "findstr" or "grep" as a second command to search the results. Each line is a result, not an excerpt:
NOTE: A blank response means there was NO match of against Device-Owner / DeviceOwner APK installed.

> adb shell dumpsys device_policy | findstr "admin"

  admin=ComponentInfo{com.pdp.deviceowner/com.pdp.deviceowner.receivers.AdminReceiver}
    com.wtmp.svdsoftware/com.wtmp.core.admin.AdminReceiver:
        179: com.ms.office365admin

> adb shell "dumpsys device_policy | grep deviceowner"

  admin=ComponentInfo{com.pdp.deviceowner/com.pdp.deviceowner.receivers.AdminReceiver}
    package=com.pdp.deviceowner
    com.pdp.deviceowner/.receivers.AdminReceiver:

However, a BETTER answer would be to change the query:

> adb shell dumpsys device_policy | findstr "package="
> adb shell "dumpsys device_policy | grep package="

  package=com.pdp.deviceowner

(just noticed @Natfoli mentioned similar answer.)
