我如何启动或停止内置圈养在Android 2.2的从我的应用程序？

How can I start or stop the built-in tethering in Android 2.2 from my application?

推荐答案

有一个在 ConnectivityManager A非公开圈养的API。如上图所示，你可以使用反射来访问它。我想这对一些Android 2.2的手机，它适用于所有的人（我的HTC打开网络共享，但不显示此状态栏......，所以从另一端检查）。下面是一些粗糙的code发射调试的东西，打开圈养在USB0。

There is a non-public Tethering API in the ConnectivityManager. As shown above you can use reflection to access it. I tried this on a number of Android 2.2 phones, and it works on all of them (my HTC turns on tethering but does NOT show this in the status bar..., so check from the other end). Below is some rough code which emits debugging stuff and turns on tethering on usb0.

ConnectivityManager cman = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

Method[] methods = cman.getClass().getDeclaredMethods();
for (Method method : methods) {
    if (method.getName().equals("getTetherableIfaces")) {
        try {
            String[] ifaces = (String[]) method.invoke(cman);
            for (String iface : ifaces) {
                Log.d("TETHER", "Tether available on " + iface);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    if (method.getName().equals("isTetheringSupported")) {
        try {
            boolean supported = (Boolean) method.invoke(cman);
            Log.d("TETHER", "Tether is supported: " + (supported ? "yes" : "no"));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    if (method.getName().equals("tether")) {
        Log.d("TETHER", "Starting tether usb0");
        try {
            int result = (Integer) method.invoke(cman, "usb0");
            Log.d("TETHER", "Tether usb0 result: " + result);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
