网络连接总是发现在手机上，即使没有网络 [英] network connection always detected on handset, even with no network

问题描述

我检查Android中的网络连接，在一个真正的手机。它总是显示Internet连接present，甚至当我关闭网络连接设置 - >位置 - >使用的无线网络 - >关闭和启用GPS statelites - >关闭，并且禁用无线

I am checking the networking connection in Android, on a real handset. It always shows "Internet Connection Present", even when I close the network connection in "Settings -> Location -> Use wireless network -> off" and "enable GPS statelites -> off" and also disable wifi.

我使用下面的code：

I am using the following code:

  private boolean checkInternetConnection() {
        ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        // test for connection
        if (cm.getActiveNetworkInfo() != null
                && cm.getActiveNetworkInfo().isAvailable()
                && cm.getActiveNetworkInfo().isConnected()) {
            Log.e("TAG", "Internet Connection Present");
            return true;
        } else {
            Log.e("TAG", "Internet Connection Not Present");
            return false;
        }

    }

我已经设置权限：

I have set permissions:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

我是什么做错了吗？

What am I doing wrong?

推荐答案

设置 - >位置 - >使用无线网络（关闭），并使用GPS卫星（关闭）如上述提到的设置来确定位置，而不是禁止访问到互联网。

'Settings->Location->Use wireless network (off) and Use GPS satellites (off)' as mentioned above are settings for determining location, not disabling access to the internet.

为了切断接入互联网完全，尽量飞行模式（设置 - >无线和网络设置 - >飞行模式）

In order to cut off access to the internet completely, try Airplane mode (Settings -> Wireless & network settings -> Airplane mode)
