    <p>I am trying to write an application that displays the list of running applications. I used activity manager for that. While running the application, It is showing the following error."UNHANDLED EVENT LOOP EXECUTION" IN ERROR LOG and application is force closing.</p> <p>Please help me to find my mistake. My code is given below.</p> <pre><code>public class ActiveApplicationsActivity extends ListActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ActivityManager am = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE); List&lt;ActivityManager.RunningAppProcessInfo&gt; l = am.getRunningAppProcesses(); String[] sl = (String[]) l.toArray(); ArrayAdapter&lt;String&gt; adapter = new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, sl); setListAdapter(adapter); } @Override protected void onListItemClick(ListView l, View v, int position, long id) { String item = (String) getListAdapter().getItem(position); Toast.makeText(this, item + " selected", Toast.LENGTH_LONG).show(); } } </code></pre> <p>I am adding the logcat information</p> <pre> 02-01 10:52:47.790: D/AndroidRuntime(333): Shutting down VM 02-01 10:52:47.790: W/dalvikvm(333): threadid=1: thread exiting with uncaught exception (group=0x40015560) 02-01 10:52:47.811: E/AndroidRuntime(333): FATAL EXCEPTION: main 02-01 10:52:47.811: E/AndroidRuntime(333): java.lang.RuntimeException: Unable to start activity ComponentInfo {com.msat.sd102268.taskmanager.activeapplications/com.msat.sd102268.taskmanager.activeapplications.ActiveApplicationsActivity}: java.lang.ClassCastException: [Ljava.lang.Object; 02-01 10:52:47.811: E/AndroidRuntime(333): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1647) 02-01 10:52:47.811: E/AndroidRuntime(333): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1663) 02-01 10:52:47.811: E/AndroidRuntime(333): at android.app.ActivityThread.access$1500(ActivityThread.java:117) 02-01 10:52:47.811: E/AndroidRuntime(333): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:931) 02-01 10:52:47.811: E/AndroidRuntime(333): at android.os.Handler.dispatchMessage(Handler.java:99) 02-01 10:52:47.811: E/AndroidRuntime(333): at android.os.Looper.loop(Looper.java:123) 02-01 10:52:47.811: E/AndroidRuntime(333): at android.app.ActivityThread.main(ActivityThread.java:3683) 02-01 10:52:47.811: E/AndroidRuntime(333): at java.lang.reflect.Method.invokeNative(Native Method) 02-01 10:52:47.811: E/AndroidRuntime(333): at java.lang.reflect.Method.invoke(Method.java:507) 02-01 10:52:47.811: E/AndroidRuntime(333): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:839) 02-01 10:52:47.811: E/AndroidRuntime(333): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:597) 02-01 10:52:47.811: E/AndroidRuntime(333): at dalvik.system.NativeStart.main(Native Method) 02-01 10:52:47.811: E/AndroidRuntime(333): Caused by: java.lang.ClassCastException: [Ljava.lang.Object; 02-01 10:52:47.811: E/AndroidRuntime(333): at com.msat.sd102268.taskmanager.activeapplications.ActiveApplicationsActivity.onCreate(ActiveApplicationsActivity.java:23) 02-01 10:52:47.811: E/AndroidRuntime(333): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 02-01 10:52:47.811: E/AndroidRuntime(333): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1611) 02-01 10:52:47.811: E/AndroidRuntime(333): ... 11 more </pre>

Guidance
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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
