我希望有人可以爲我的問題提供解決方案。我花了很多時間尋找解決方案，包括這個論壇，但都沒有成功。Android套接字客戶端超時
我有一個PHP套接字服務器運行，我試圖讓我的Android應用程序連接到它並交換數據。我知道PHP服務器的工作，至少對於一個PHP客戶端，所以我猜這個問題是在Android客戶端內的某個地方。
該應用程序在Android 7" 平板電腦上運行的Android 2.1
下面是什麼，我認爲，最相關的代碼片斷。我想提一提，這種情況是很重要的兩個時，有Wi-Fi連接我確信我不需要清單中顯示的所有權限，但是我在其中一個讀取的線索的建議中包含了它們。
拋出的異常說：「java.net .SocketTimeoutException：Socket未連接「。我試過增加超時限制，但沒有運氣
這是androi
import java.net.InetSocketAddress;
import java.net.Socket;
import java.net.SocketAddress;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class test extends Activity{
private static final String TAG = "socketTest";
public SocketAddress remoteAdr = new InetSocketAddress("111.222.333.444", 1234);
public Socket socket;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Log.d(TAG, "Start the socket thread..");
startThread();
}
void startThread(){
Thread t = new Thread(){
public void run(){
Log.d(TAG, "Socket thread started !");
boolean loop = true;
while(loop){
try{
Log.d(TAG, "Create the socket");
socket = new Socket();
Log.d(TAG, "Try to connect the socket");
socket.connect(remoteAdr, 15000);
Log.d(TAG, "I'm never shown..");
}catch(Exception e){
Log.e(TAG, "Error when connecting: " + e);
}
Log.d(TAG, "Done trying");
loop = false;
}
}
};
t.start();
}
}
我的清單文件看起來像這樣：嘗試連接到外部服務器d客戶

的PHP套接字服務器：
$loop = 1;
set_time_limit (1);
// set some variables
$host="111.222.333.444";
$port = 1234;
// Create the socket, bind it to a port and start listening (accepts 3 connectinons in the queue).
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP) or die("Could not create socket \n");
$result = socket_bind($socket, $host, $port) or die("Could not bind to socket \n");
$result = socket_listen($socket, 3) or die("Could not set up socket listener \n");
do{
// spawn another socket to handle communication and
$spawn = socket_accept($socket) or die("Could not accept incoming connection \n");
// Accept incoming connections and wait for user input
$input = socket_read($spawn, 1024) or die("Could not read input \n");
switch(trim($input)){
case "someCase":{
// do something here, f.x. connect to a database
// code omitted
break;
}
case "END":
{
$loop = 0;
break;
}
}while($loop);
socket_close($socket);
我已經試過看我的InetSocketAddress是否有效
InetSocketAddress p1 = (InetSocketAddress)remoteAdr;
Log.d(TAG, "isUnresolved: " + p1.isUnresolved());
使用我的正確IP地址和端口號將返回false。
然後爲了比較，我嘗試了一個不存在的不同IP地址。這在isUnresolved（）檢查上返回true。 port.connect（）拋出一個UnknownHostException，並顯示消息「Host is unresolved」。
從這個測試我猜我的InetSocketAddress是有效的。
有沒有人有線索爲什麼我的客戶得到超時？
編輯： 我在HTC Desire上試過我的代碼（見上面），並且日誌顯示了相同的信息，因此看起來好像這個問題沒有修復到我的平板電腦上。我在代碼中丟失了什麼，無論是在客戶端還是服務器端？
我想知道服務器是否拒絕連接，這就是客戶端超時的原因。我的意思是我的InetSocketAddress是有效的，所以我必須做正確的事情。
我包含用「adb logcat t：D AndroidRuntime：E」生成的日誌。有沒有人有一個線索閱讀這篇日誌

爲了明顯地避免這種情況發生，您可以從平板電腦上的瀏覽器訪問該ip addy，還是通過平板電腦上的外殼ping它？ – Torp 2011-04-07 19:11:04
是的，如果我在平板電腦的瀏覽器中輸入我的IP地址，我會得到200 OK響應。 – skari 2011-04-08 08:57:38
我應該使用PHP套接字服務器以外的東西嗎？ – skari 2011-07-07 14:06:18
