Android6，设置全局设置WIFI_DEVICE_OWNER_CONFIGS_LOCKDOWN

Question

在Android6中，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，在运行前面的代码时，我在执行mDevicePolicyManager.setGlobalSetting时总是会得到一个安全异常

有什么想法吗？

Answer 1

更新：

设置权限时

android:permission="android.permission.BIND_DEVICE_ADMIN

对于接收方，可以将接收方添加到DeviceAdministration，其策略定义为：

Android:resource=“@xml/设备_admin_sample”

要激活DeviceAdministration，您必须转到设备的设置->Security->DeviceAdministration，并激活它以使用管理功能。

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

我想说的是，您必须是执行此操作的根用户。我现在需要为我的公司做同样的事情，但我们有根本的权利。如果我有更多关于这个问题的信息，我会在稍后更新这个答案。
