android連接到http拒絕

Question

我想發送一些數據到其他計算機上的本地主機服務器，但我做不到。我使用的是mac，我的防火牆默認是禁用的。我用另一臺電腦的IP地址，我們在同一個網絡。我確實輸入了所需的權限。

這是logcat的消息

09-22 08:06:46.343: D/OpenGLRenderer(1108): Enabling debug mode 0

09-22 08:08:01.379: D/InputStream(1108): Connection to http://172.22.111.225:8080 refused 

這是我的代碼

public class MainActivity extends Activity implements OnClickListener {

    etTwitter = (EditText) findViewById(R.id.etTwitter); 
    btnPost = (Button) findViewById(R.id.btnPost); 

    // check if you are connected or not 
    if(isConnected()){ 
     tvIsConnected.setBackgroundColor(0xFF00CC00); 
     tvIsConnected.setText("You are conncted"); 
    } 
    else{ 
     tvIsConnected.setText("You are NOT conncted");

    // add click listener to Button "POST" 
    btnPost.setOnClickListener(this); 

}
