BindException with INTERNET permission requested
- by Mondain
I have seen several questions regarding SocketException when using Android, but none of them cover the BindException that I get even with the INTERNET permission specified in my manifest.
Here is part of my manifest:
<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>
Here is the relevant portion of my LogCat output:

I Really hope this is a simple problem and not something complicated by the fact that the binding is occurring within a worker thread on a port less than 1024.
Update
Looks as if this is a privileged port issue, anyone know how to bind to ports lower than 1024 in Android?
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();
}
