Question

使用Android 6，我想设置全局设置WIFI_DEVICE_OWNER_CONFIGS_LOCKDOWN，这就是我所做的：

mDevicePolicyManager = (DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE);
deviceAdminComponentName = new ComponentName(this, MyDeviceAdminReceiver.class);
try {
    Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
    intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN,deviceAdminComponentName);
    intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION,"Your boss told you to do this");
    startActivityForResult(intent, ACTIVATION_REQUEST);

}catch (Exception e){
    Logg.d("Error: " + e.getMessage());
}

其中MyDeviceAdminReceiver是一个扩展DeviceAdminReceiver的类。

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
    case ACTIVATION_REQUEST:
        if (resultCode == Activity.RESULT_OK) {

            try {
                mDevicePolicyManager.setGlobalSetting(deviceAdminComponentName, Settings.Global.WIFI_DEVICE_OWNER_CONFIGS_LOCKDOWN, "1");

             }catch (Exception e){
                Logg.e("Error " + e.getMessage());
             }

        } 
        return;
    }
    super.onActivityResult(requestCode, resultCode, data);
}


<receiver android:name=".MyDeviceAdminReceiver" android:permission="android.permission.BIND_DEVICE_ADMIN">
    <meta-data android:name="android.app.device_admin"
              android:resource="@xml/device_admin_sample" />
    <intent-filter>
        <action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
    </intent-filter>
</receiver>

<device-admin xmlns:android="http://schemas.android.com/apk/res/android">
    <uses-policies>
        <limit-password />
        <watch-login />
        <reset-password />
        <force-lock />
        <wipe-data />
        <expire-password />
        <encrypted-storage />
        <disable-camera />
        <set-global-proxy/>
        <disable-keyguard-features/>
    </uses-policies>
</device-admin>

不幸的是，在运行上一代码时，我总是在执行mDevicePolicyManager.setGlobalSetting

时遇到安全异常

有什么想法吗？

更新

设置权限时

机器人：权限=“android.permission.BIND_DEVICE_ADMIN

对于接收器，您将接收器添加到DeviceAdministration，并在以下位置定义策略：

机器人：资源= “@ XML / device_admin_sample”

要激活设备管理，您必须转到设备的设置 - >安全性 - >设备管理并激活它以使用管理功能。

java.lang.SecurityException：Admin ComponentInfo {com .... / com .... MyDeviceAdminReceiver}不拥有设备

我会说你必须是root用户才能做到这一点。我现在需要为我的公司做同样的事情，但我们拥有root权利。如果我有更多相关信息，我会在稍后更新这个答案。
