当我尝试命令时： 我得到如下错误

admins-MacBook-Pro:platform-tools devrath$ ./adb shell dpm set-device-owner eu.sisik.devowner/.DevAdminReceiver
    usage: dpm [subcommand] [options]
    usage: dpm set-active-admin [ --user <USER_ID> | current ] <COMPONENT>
    usage: dpm set-device-owner [ --user <USER_ID> | current *EXPERIMENTAL* ] [ --name <NAME> ] <COMPONENT>
    usage: dpm set-profile-owner [ --user <USER_ID> | current ] [ --name <NAME> ] <COMPONENT>
    usage: dpm remove-active-admin [ --user <USER_ID> | current ] [ --name <NAME> ] <COMPONENT>

    dpm set-active-admin: Sets the given component as active admin for an existing user.

    dpm set-device-owner: Sets the given component as active admin, and its package as device owner.

    dpm set-profile-owner: Sets the given component as active admin and profile owner for an existing user.

    dpm remove-active-admin: Disables an active admin, the admin must have declared android:testOnly in the application in its manifest. This will also remove device and profile owners.

    dpm clear-freeze-period-record: clears framework-maintained record of past freeze periods that the device went through. For use during feature development to prevent triggering restriction on setting freeze periods.

    dpm force-security-logs: makes all security logs available to the DPC and triggers DeviceAdminReceiver.onSecurityLogsAvailable() if needed.

    Error: Unknown admin: ComponentInfo{eu.sisik.devowner/eu.sisik.devowner.DevAdminReceiver}

Answer 1

I figured out the problem: I had given the package name wrong

正确的格式是：

admins-MacBook-Pro:platform-tools devrath$ ./adb shell dpm set-device-owner com.cnx.silentupdate/.DevAdminReceiver
