    <p>I have a client-sever app on android,both running on the same machine. In the first activity of my client app I try to call client class which should connect to the server application,but I get force close.</p> <p>This is how I call the client class in the first activity of my app:</p> <pre><code>Thread cThread=new Thread(new ClientThread()); cThread.start(); </code></pre> <p>and here is my client class:</p> <pre><code>public class ClientThread implements Runnable{ private Handler handler=new Handler(); Socket socket; private TextView clientState; public void run() { try { InetAddress serverAddr=InetAddress.getByName("10.0.2.2"); handler.post(new Runnable(){ public void run(){ clientState.setText(" try to connect!"); } }); socket=new Socket(serverAddr, 8080); //connected=true; handler.post(new Runnable(){ public void run(){ clientState.setText("Connected!"); } }); } catch(Exception e){ handler.post(new Runnable(){ public void run(){ clientState.setText("Error"); } }); e.printStackTrace(); } } protected void onStop() { super.onStop(); try { // make sure you close the socket upon exiting //out.close(); socket.close(); } catch (IOException e) { e.printStackTrace(); } } } </code></pre> <p>Can someone tell what is wrong or at least give me an ideea. One thing that I should say is that my client works fine-it connects to the server,when the client class is integrated in my first activity(I mean,initially I had no client class was all in the first activity...and it worked fine). I'm here for further details! Thank u in advance!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
