Question

I am completly new to android programming and I try to get clicking on an android widget working:

public class MyWidget extends AppWidgetProvider {
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
        int[] appWidgetIds) 
{
// Loop through all widgets
for(int i=0;i < appWidgetIds.length;i++) {
    int appWigedid = appWidgetIds[i];
    // Create an intent to launce something
    Intent intent = new Intent(context,TestActivity.class);
    PendingIntent pendingintent = PendingIntent.getActivity(context, 0, intent, 0);


    // Get the layout for the app widget and attach on click listener
    RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.initial_layout);
    views.setOnClickPendingIntent(R.id.UselessMessage, pendingintent);
    views.setTextViewText(R.id.UselessMessage,"This text is useless");
    AppWidgetManager manager = AppWidgetManager.getInstance(context);
    manager.updateAppWidget(appWigedid,views);
}
}

my TestActivity class is just a stub because still trying to find out how it is called.

public class TestActivity extends Activity {
@Override
protected void onStart() {
    System.out.println("On Start called!");
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    System.out.println("on create called!");
};

}

The setting of the Text works. But the onStart method of the TestAcitivity is never executed (other sysout messages work). When I tap on the widget android logs:

12-25 17:17:43.054  1279  1392 I ActivityManager: Starting activity: Intent { flg=0x10000000 cmp=org.rfc1149.android.simple/.TestActivity bnds=[120,272][360,371] }

which would suggest that the activity is created but the onCreate does not work.

Make sure your TestActivity is defined in your manifest.
