I have a couple questions, please join the site so you can reply in this thread. See this link for instructions on how to join Android Central.

Have you tried restarting the phone? What is the make and model of the phone? Have you tried deleting the app and reinstalling? This is happening to all apps, or just a few, or just one? What app or apps? Do you have a solid cellular or WiFi signal? (this is relevant IF the app needs to communicate with a server or the internet, for example a weather app, or an IM app)
