android app-widget broadcast-receiver Java

I'm following best practices but I'm attempting to set up I'm working on a project and hit a roadblock... I'm building an Android app that includes an App Widget. I've set it up to display some dynamic content based on user preferences, but after changing the configuration (like updating the user settings), the widget doesn't reflect the changes unless I manually refresh it. I've tried using `AppWidgetManager.updateAppWidget()` with the updated RemoteViews, but it doesn't seem to trigger the update as expected. Here's a snippet of my code where I'm trying to update the widget: ```java public void updateWidget(Context context) { AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context); int[] appWidgetIds = appWidgetManager.getAppWidgetIds(new ComponentName(context, MyAppWidgetProvider.class)); for (int appWidgetId : appWidgetIds) { RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout); // Assuming userPreference is updated based on new settings views.setTextViewText(R.id.widget_text, userPreference); // Update the widget appWidgetManager.updateAppWidget(appWidgetId, views); } } ``` I also have a `BroadcastReceiver` that listens for changes in user preferences: ```java public class UserPreferenceReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { // Call the method to update the widget updateWidget(context); } } ``` The receiver is registered in the `AndroidManifest.xml`, and it seems to be triggered when preferences change. However, the widget still doesn't show the latest value until I reboot the device. I've verified that `userPreference` holds the new value when `updateWidget()` is called. Is there something I'm missing here? Should I maybe be using a different approach to ensure that the widget updates properly after configuration changes? Any suggestions on best practices for dynamically updating App Widgets would be greatly appreciated. The stack includes Java and several other technologies. Any feedback is welcome! This is happening in both development and production on Windows 11. I'm open to any suggestions. This is my first time working with Java stable. I appreciate any insights!
