如何从我的应用程序启动或停止Android 2.2中的内置网络共享?

ConnectivityManager
中有一个非公开的Tethering API。如上所示,您可以使用反射来访问它。我在许多Android 2.2手机上试过这个,它适用于所有这些(我的HTC打开了网络共享,但没有在状态栏中显示...,所以从另一端检查)。下面是一些粗略的代码,它们发出调试内容并打开usb0上的tethering。
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();
}
}
}
请注意:此代码需要以下权限才能运行:
android.permission.ACCESS_NETWORK_STATE
android.permission.CHANGE_NETWORK_STATE

我回答了这个问题here。简而言之,可能,这是代码:
private void setWifiTetheringEnabled(boolean enable) {
WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
Method[] methods = wifiManager.getClass().getDeclaredMethods();
for (Method method : methods) {
if (method.getName().equals("setWifiApEnabled")) {
try {
method.invoke(wifiManager, null, enable);
} catch (Exception ex) {
}
break;
}
}
}
您的应用应具有以下权限:
android.permission.CHANGE_WIFI_STATE

Android SDK中没有用于管理网络共享的公共API - 抱歉!

我使用了来自Android How to turn on hotspot in Android Programmatically的代码!我为Android 4.2启用了便携式热点。这是代码。
WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
// TODO Auto-generated method stub
WifiConfiguration wifi_configuration = null;
wifiManager.setWifiEnabled(false);
try
{
//USE REFLECTION TO GET METHOD "SetWifiAPEnabled"
Method method=wifiManager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);
method.invoke(wifiManager, wifi_configuration, true);
}
catch (NoSuchMethodException e){
// TODO Auto-generated catch block
e.printStackTrace();
}catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}catch (InvocationTargetException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
