我再次遇到了Android中套接字編程的問題。我的問題是Selector.select()返回零,表示沒有SocketChannel準備寫入。再次,相同的代碼在普通的Java中工作,但在Android中不起作用。這裏是我的代碼:SocketChannel還沒有準備好
package com.test;
import java.io.IOException;
import java.net.InetSocketAddress;
import java.net.SocketAddress;
import java.nio.channels.ClosedChannelException;
import java.nio.channels.Selector;
import java.nio.channels.SocketChannel;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class WebSocketTest extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
SocketChannel channel = null;
SocketAddress socketAdress = new InetSocketAddress("10.0.0.1", 8787);
try {
channel = SocketChannel.open();
} catch (IOException e) {
Log.e("ERROR", "channel open");
}
try {
channel.configureBlocking(false);
} catch (IOException e1) {
Log.e("ERROR", "channel blocking");
}
try {
channel.connect(socketAdress);
} catch (IOException e) {
Log.e("ERROR", "channel connect");
}
try {
while(!channel.finishConnect())
{
}
} catch (IOException e1) {
Log.e("ERROR", "channel finishConnect");
}
Selector selector = null;
try {
selector = Selector.open();
} catch (IOException e) {
Log.e("ERROR", "selector open");
}
try {
channel.register(selector, channel.validOps());
} catch (ClosedChannelException e) {
Log.e("ERROR", "channel register");
}
boolean i = true;
while(i)
{
int readyChannels = 0;
try {
readyChannels = selector.select();
} catch (IOException e) {
Log.e("ERROR", "selector select");
}
if(readyChannels > 0)
{
i = false;
}
}
}
}
在Java readyChannels = 1。在Android中爲0。 誰能幫助我?
您是否對模擬器和設備都有這個問題? – 2010-11-02 22:27:32
