请求INTERNET权限的BindException

Question

我在使用Android时看到了几个关于SocketException的问题,但是它们都没有涵盖我得到的BindException,即使我的清单中指定了INTERNET权限.

这是我的清单的一部分:

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>

<uses-permission android:name="android.permission.READ_OWNER_DATA"></uses-permission>
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>

<uses-permission android:name="android.permission.ACCOUNT_MANAGER"></uses-permission>
<uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS"></uses-permission>

04-22 14:49:06.117: DEBUG/MyLibrary(4844): Address to bind: 192.168.1.14 port: 843
04-22 14:49:06.197: WARN/System.err(4844): java.net.BindException: Permission denied (maybe missing INTERNET permission)

04-22 14:49:06.227: WARN/System.err(4844):     at java.net.ServerSocket.bind(ServerSocket.java:367)
04-22 14:49:06.237: WARN/System.err(4844):     at org.apache.harmony.nio.internal.ServerSocketChannelImpl$ServerSocketAdapter.bind(ServerSocketChannelImpl.java:283)
04-22 14:49:06.237: WARN/System.err(4844):     at mylibrary.net.PolicyConnection$PolicyServerWorker.(PolicyConnection.java:201)

这是我的LogCat输出的相关部分:

    SelectorProvider provider = SelectorProvider.provider();
    try {
        ServerSocketChannel channel = provider.openServerSocketChannel();
        policySocket = channel.socket();
        Log.d("MyLibrary", "Address to bind: " + device.getAddress().getAddress() + " port: 843");              
        InetSocketAddress addr = new InetSocketAddress(InetAddress.getByName(device.getAddress().getAddress()), 843);
        policySocket.bind(addr);
        policySocket.setReuseAddress(true);
        policySocket.setReceiveBufferSize(256);
    } catch (Exception e) {
        e.printStackTrace();
    }

我真的希望这是一个简单的问题,并不是因为绑定发生在小于1024的端口上的工作线程中这一事实.

更新

看起来这是一个特权端口问题,任何人都知道如何绑定到Android中低于1024的端口？

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>

<uses-permission android:name="android.permission.READ_OWNER_DATA"></uses-permission>
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>

<uses-permission android:name="android.permission.ACCOUNT_MANAGER"></uses-permission>
<uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS"></uses-permission>

有谁知道如何绑定到Android中低于1024的端口？

要么手机根,修改固件,要么不绑定到1024以下的端口.这比Linux更重要.
