    <p>I implemented an Android Application with following features:</p> <p>Application: <code>public class ApplicationGlobalAgent extends Application</code> contains:</p> <ul> <li>a MainActivity: to display GUI drawing -> and start other activities from it.</li> <li>a network ServerSocket and a client Socket: to send/receive data in duplex mode.</li> </ul> <p>I want to terminate Application when MainActivity finish, I did as follow:</p> <p><strong>In MainActivity extends Activity:</strong></p> <pre><code>@Override public void finish() { super.finish(); Log.d(DEBUG_TAG, "finish and call app termination"); //call the application to terminate getApplication().onTerminate(); } </code></pre> <p><strong>In ApplicationGlobalAgent extends Application:</strong></p> <pre><code>@Override public void onTerminate() { // do close ServerSocket and client Socket in networking threads mNetworkManager.DoStop(); System.gc(); Log.d(DEBUG_TAG, "Terminated!"); super.onTerminate(); //?? should be placed at the end of functions ?? //totally kill this application process android.os.Process.killProcess(android.os.Process.myPid()); } </code></pre> <p><strong>BUT results are:</strong> </p> <p>When have no network connection, the application terminates successfully, otherwise <code>"Terminated!"</code> is never printed until I close the network sockets at other side (who connected to the Android sockets).</p> <p>So, How can I <strong>force the application to properly and fully terminate</strong> when exit the MainActivity with connecting network sockets?</p> <p>Appreciate all your helps!</p>

    1. COTo be brutally honest, almost everything here is incorrect. I *strongly* encourage you to read through the documentation on [**the process lifecycle**](http://developer.android.com/reference/android/app/Activity.html#ProcessLifecycle) and [**the `Activity` lifecycle**](http://developer.android.com/guide/components/activities.html#Lifecycle).

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.
