我知道问题已被问到,但我无法获得设备所有权.

我用的是带有android 7.0的三星xcover 4.

我启动此命令：

C:\Users\xxx\AppData\Local\Android\Sdk\platform-tools>adb shell dpm set-device-owner org.wso2.iot.system.service/.ServiceDeviceAdminReceiver

我收到此错误：

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

工厂重置完成.
我也禁用和卸载所有应用程序,但仍然没有运气.有解决方案吗
谢谢.

解决方法:

正如错误所述

because there are already some accounts on the device

转到设置 – >帐户并删除所有帐户(例如Gmail,Facebook,…).如果没有其他帐户,请重试.
