我尝试使用谷歌搜索,但我发现的只是Adobe和Freshplanets NetworkInfo ANE的NetworkInfo。由于某种原因,NetworkInfo无法正常工作,而且newplanets network-info API无法做到这一点。还有其他方法可以完成这项任务吗?
我从这个使用networkInfo的链接下载了这个例子:[http://www.adobe.com/devnet/air/native-extensions-for-air/extensions/networkinfo.html][1]
以下是上面示例中主类的代码:

package
{
import com.adobe.nativeExtensions.Networkinfo.InterfaceAddress;
import com.adobe.nativeExtensions.Networkinfo.NetworkInfo;
import com.adobe.nativeExtensions.Networkinfo.NetworkInterface;
import flash.display.Sprite;
import flash.display.StageAlign;
import flash.display.StageScaleMode;
import flash.text.TextField;
import flash.text.TextFormat;
public class NetworkInfoUsageApp extends Sprite
{
private var info:TextField;
public function NetworkInfoUsageApp()
{
super();
stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;
var ntf:Vector.<NetworkInterface> = NetworkInfo.networkInfo.findInterfaces();
info = makeTextField(50, 50);
for each (var interfaceObj:NetworkInterface in ntf)
{
trace("Interface Name:" + interfaceObj.name + "
" );
trace("MTU:" + interfaceObj.mtu.toString + "
" );
trace("Display Name of the Interface:" + interfaceObj.displayName + "
" );
trace ("Active ?" + interfaceObj.active.toString() + "
" );
trace("Hardware Address:" + interfaceObj.hardwareAddress + "
");
info.appendText("Interface Name:" + interfaceObj.name + "
" );
info.appendText("MTU:" + interfaceObj.mtu.toString() + "
" );
info.appendText("Display Name of the Interface:" + interfaceObj.displayName + "
" );
info.appendText("Active ?" + interfaceObj.active.toString()+ "
");
info.appendText("Hardware Address:" + interfaceObj.hardwareAddress + "
");
for each(var address:InterfaceAddress in interfaceObj.addresses)
{
trace("Address" + address.address + "
");
trace("broadcast address" + address.broadcast + "
");
trace("ipversion" + address.ipVersion + "
")
trace("prefixlength" + address.prefixLength +"
")
info.appendText("Address" + address.address + "
" );
info.appendText("broadcast address" + address.broadcast + "
" );
info.appendText("ipversion" + address.ipVersion + "
");
info.appendText("prefixlength" + address.prefixLength +"
" );
}
}
}
private function makeTextField(x:Number, y:Number):TextField
{
var tf:TextField = new TextField();
tf.x = x;
tf.y = y;
tf.border=true;
this.stage.addChild(tf);
tf.height = 800;
tf.width = 450;
tf.type = "input";
var tff:TextFormat=new TextFormat();
tff.size=18;
tff.color=0x0000ff;
tf.defaultTextFormat=tff;
tf.setTextFormat(tff);
tf.text="hello";
return tf;
}
}
}
当我从Flash Pro运行电影时,我收到此错误:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

当我发布apk并在我的设备上运行它。什么都没有,只有白色。
并非所有移动设备都支持NetworkInfo。轮询isSupported标志,看看你是否有权访问。如果你这样做,只需将findInterfaces()调用为retreive和NetworkInterface对象数组。
我找到了另一个令人敬畏的ANE,它完美无缺。它被称为“WifiTags”。它适用于Windows和android。感谢所有回答的人。
