如何检查在Android上网（包括圈养！）？ [英] How to check internet access (INCLUDING tethering!) on Android?

问题描述

我找了一块code的，将检查Android设备，包括圈养，不仅无线信道的网络连接。

I am looking for a piece of code that would check network connectivity, of an Android device, including tethering, not only the wireless channels.

我在网上花了几个小时寻找这样的事情，但没有任何结果！所有我发现功能仅管理无线网卡的测试。有没有什么束缚。那么，这至少可能吗？你有没有一些相应的？

I have spent hours online looking for such a thing, but without any result! All the functions I found out manage only wireless net tests. Nothing with tethering. So is it at least possible? Do you have some corresponding?

推荐答案

此检查是否启用了圈养。从类切我改变让adbWireless工作过绳连接：

this checks if Tethering is enabled. Cut from a class I changed to get adbWireless working over a tethered connection:

    // check if tethering is on
    try {
        Method[] wmMethods = mWifiManager.getClass().getDeclaredMethods();
        for(Method method: wmMethods)
            if(method.getName().equals("isWifiApEnabled")) {
                boolean isOn = (Boolean) method.invoke(mWifiManager);
                return isOn;
            }
        return false;
    } catch (Exception e) {return false;}

和则还需要android.permission.ACCESS_WIFI_STATE

And you also need android.permission.ACCESS_WIFI_STATE
