How to process all keys, including: F1,F2,F4,F5,F6,F10, on USB keyboard connected to android?

Question

Android

I am writing a terminal client for android. I am connecting a keyboard to a USB device. I need to process ALL keystrokes in it, not allowing any action to be performed outside of my application. I write dispatchKeyEvent(KeyEvent event) which always returns true - If I understand correctly, I'm saying that I handled the event and no one should handle it anymore. But, nevertheless, on the keys: F1, F2, F4, F5, F6, F10, the android minimizes my application and performs some actions. Unfortunately, I have no experience with android, so I don't understand what to do to avoid the standard action, but simply pass the keycode scan to my application. Please tell me if anyone knows.

Google has a tutorial on handling keypresses. Key codes F1-F12 correspond to KeyEvent.KEYCODE_F1 - KeyEvent.KEYCODE_F12. A list of all codes can be found at developer.android.com/reference/android/view/KeyEv...
