如何在 Android 模拟器中启用 VPN 支持

Question

我喜欢在 Android 模拟器中使用 PPTP VPN。我的 VPN 提供商是 Witopia。这些设置适用于真机 (HTC Desire)。

它不起作用，一段时间后连接超时。

adb logcat 打印：

D/VpnManager( 1527): succeeded to connect to VPN service
D/com.android.settings.vpn.AuthenticationActor( 1527): ~~~~~~ connect() succeeded!
I/SProxy_mtpd( 2211): Stop VPN daemon: mtpd

后跟用户消息：无法连接到网络。你想再试一次吗？

同时在adb logcat

E/VpnService( 2211): onError()

我猜这要么是权限问题，要么是安卓模拟器不支持。

我的平台是 MacOSX，模拟器运行的是 Android 2.2。

Answer 1

是的，这就像内核问题：

1. 没有 tun.ko 模块（参见http://forum.xda-developers.com/showthread.php?t=630703&page=2）
2. 不支持 lkm（可加载内核模块）(http://code.google.com/p/get-a-robot-vpnc/issues/detail?id=100)

所以我认为您需要自定义内核 http://code.google.com/p/batterymine/wiki/BuildingInModuleSupport

您还需要将其他模块复制到模拟器：slhc.ko、ppp*.ko

Answer 2

我在使用 2.2 模拟器时遇到了同样的问题。我切换到 4.2 的模拟器，它通过 VPN 运行良好。
