How can I hide or remove the status bar in Android HoneyComb? Every time I run my application, I find some contents have to be covered by the status bar.
I have try to change the AndroidManifest.xml, but nothing changed.
You don't. It's considered a permanent screen decoration in the same way that capacitive home/menu/etc. buttons below the touchscreen on Android phones are.
How are you measuring the space available for your content?
Intrications
You can only dim the status bar. See How do I dim the system bar in Android 3.0 (Honeycomb)?
