Widget replaced by other content when programmatically refreshing in Android
android, android-widget
Solution
I had some problems with widgets in the past, and have solved them. I really do not know the reason why my solution worked for me. And as it worked for Marco W., so I place it here: all I did was moved the update code to a service. When I need to update, start that service. Again, I'm not sure about that but the problems were solved.
Thanks Marco, I got some more experiences with Android. It's funny :-)
Problem
Somewhere here on Stack Overflow, I had found the following code some day which I adjusted to my application a bit: ``` private void updateWidget() { AppWidgetManager widgetManager = AppWidgetManager.getInstance(ctx); ComponentName widgetComponent = new ComponentName(ctx, MyAppWidgetProvider.class); int[] widgetIds = widgetManager.getAppWidgetIds(widgetComponent); Intent update = new Intent(); update.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, widgetIds); update.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE); ctx.sendBroadcast(update); } ``` This should programmatically refresh all instances of the application's widget. `ctx` is the `Activity`'s context (`this`) that I set once in `onCreate()`. The method above is called in the `Activity`'s `onStop()` method. Unfortunately, when it is called, it replaces the app's widget by other apps' widgets (e.g. AP News) - at least for a while. How can this happen? Is there something wrong in the code? Thank you! Edit #1: To point this out more clearly: I've already defined an interval for automatic refreshing. But in addition to that, I would like to update the widget from the `Activity` from time to time. This question suggests that it is possible as well. Edit #2: I've just seen that the wrong widget is only shown for some seconds. After that, my own app's widget is shown again.
