Steps to clear application cache on your HTC Hero with Google
Clearing the application cache removes temporary files and frees up memory - your personal settings or information remain intact.
Be sure you clear only the application cache and not the application data.
- From the home screen, press the Menu key.
- Tap Settings.
- Scroll to and tap Applications.
- Tap Manage applications.
- Scroll to and tap the preferred application.
- Tap Clear cache.
- You've now cleared the application cache.
