getOutputStream（）上的設備上的「no host to host」（無線連接） - 無線連接

private String urlPost = "http://192.168.1.66:8080/DataCollectionServlet/"; 

@Override 
protected void doWakefulWork(Intent intent) { 
    // https://stackoverflow.com/q/14630255/281545 
    HttpURLConnection connection = null; 
    try { 
     connection = connection(); 
     w("connection"); // allrigt 
     final OutputStream connOutStream = connection.getOutputStream(); 
     w("GEToUTPUTsTREAM"); // I never see this 
    } catch (IOException e) { 
     e.printStackTrace(); // No route to host 
    } finally { 
     if (connection != null) connection.disconnect(); 
    } 
} 

private HttpURLConnection connection() throws MalformedURLException, 
     IOException { 
    HttpURLConnection connection = (HttpURLConnection) new URL(urlPost) 
      .openConnection(); 
    // connection.setDoInput(true); 
    connection.setDoOutput(true); // triggers POST 
    // connection.setUseCaches(false); // needed ? 
    // TODO : http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html

    return connection; 
}

192.168.1.66:8080/DataCollectionServlet/中的服務器已啓動並正在運行。我的device IP是192.168.1.65。我禁用了窗口和路由器的防火牆都無濟於事。getOutputStream（）上的設備上的「no host to host」（無線連接） - 無線連接

評論：同樣，電話和PC都連接到同一個路由器無線地（相同SSID）

的Android 2.3.7埃克萊爾，HTC的Nexus 1 - 它可能是一個錯誤？

看起來好像您的設備不在您的本地網絡中，而是在單獨的網絡上（公共或其他方式分開）。你有WLAN嗎？它是否連接到本地網絡的WLAN？ – Codo

@Codo：電腦是'192.168.1.66'而電話'192.168.1.65' - 他們都連接到相同的路由器無線，是（相同的SSID） –

您是否嘗試輸入URL到Android設備的瀏覽器？ – Merlin

ANA解釋仍然有興趣好吧好吧 - 禁用我好嗎連接在路由器上（WPA-PSK）加密。我會接受作爲答案（編程）圍繞

編輯：輸入到Android設備的瀏覽器的URL我看到doGet()頁面。我重新啓用了所有的防火牆 - 唯一有所作爲的是打開和關閉加密
