Push notification for content resolver from content provider

I want to know if there is a way to inform content resolver/s if the content provider change data.

In my case there is an app that shows data base content. There is another app, that modifies data in db. Now I want to know if it开发者_开发技巧's possible to notify the app via push that data has changed in background.

I do not found any information about content resolver connecting to content provider. Also I know no way to communicate between content provider and resolver the wrong way.

Do anybody now if its possible or has a better idea.

Have you tried using a ContentObserver?
