How to start a service from App Widget in Android

I am making a home screen App Widget for my Android app. In that App Widget there is a ListView. That ListView has a custom layout which has a TextView & an ImageButton. I am setting a PendingIntent on that ImageButton to start the service as follows:

        Intent intent = new Intent(mContext, MyService.class);
        intent.putExtra(MyConstants.MY_EXTRA, c.getString(c.getColumnIndex(MyColumns.MY_COLUMN_TITLE)));
        intent.setAction(MyConstants.MY_ACTION);
        PendingIntent pendingIntent = PendingIntent.getService(mContext, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        rv.setOnClickPendingIntent(R.id.MyImageButton, pendingIntent);

in getViewAt method of RemoteViewsFactory. But on clicking the ImageButton the service does not start.

I have put an intentfilter with MY_ACTION for MyService. And also tried without it which did not make things work.

Anyone knows how to start service on click of a button inside a list view item in home screen App Widget in Android?

Everything works fine i.e. the ListView is populated perfectly from SQLite database.

From the android javadoc

public void setOnClickPendingIntent Equivalent to calling setOnClickListener(android.view.View.OnClickListener) to launch the provided PendingIntent. When setting the on-click action of items within collections (eg. ListView, StackView etc.), this method will not work. Instead, use {@link RemoteViews#setPendingIntentTemplate(int, PendingIntent) in conjunction with RemoteViews#setOnClickFillInIntent(int, Intent).

In your update method of your AppWidgetProvider you have to add

final PendingIntent clickPendingIntentTemplate = PendingIntent.getService...
views.setPendingIntentTemplate(R.id.widget_list, clickPendingIntentTemplate);

and in the getViewAt method of your RemoteViewsFactory :

final Intent fillInIntent = new Intent();
fillInIntent.putExtra(...);
views.setOnClickFillInIntent(R.id.widget_list_item, fillInIntent);
