Widget not deleted when passing RESULT_CANCELED as result for configuration activity

Question

I have some problems with my widgets. Here is the description:

Context:

I have a home widget.

When I add it, it pops a configuration

Answer 1

I solved this problem like this,

in the widget provider's onUpdate() method I check if the widget was configured, and if it wasn't I don't do anything, so no ghost widgets. At the end of the configuration I just set it to true and I'm good to go. Just don't forget to remove it from sharedpreference when the widget is deleted.

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds)
{
    super.onUpdate(context, appWidgetManager, appWidgetIds);

    for(final int appWidgetId : appWidgetIds)
    {
        final StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.append(appWidgetId);
        stringBuilder.append("_conf");
        if(context.getSharedPreferences("settings",0).getBoolean(stringBuilder.toString(),false)) 
            updateAppWidget(context,appWidgetId,appWidgetManager);

    }
