I need handle not event incomming to current view, but all eventwhich are sent to application by system.

I'm not sure I understand. From what I know, key and touch events are sent to views and dialogs. Could you explain more in detail what you are trying to achieve with your application?

@codespy: Use what @Key mentioned in an abstract class that extends `Activity` and make all your Activities extend from that one.

A:
Just add the following to your initial Activity:
// generic Key Listener
public boolean onKeyDown(int keyCode, KeyEvent event)
{
Log.d("Activity", "Key pressed"+keyCode);
switch (keyCode)
{
case KeyEvent.KEYCODE_BACK:
Log.d("Activity", "Back Key pressed");
return true;
case KeyEvent.KEYCODE_MENU:
Log.d("Activity", "Menu Key pressed");
return true;
case KeyEvent.KEYCODE_HOME:
Log.d("Activity", "Home Key pressed"); // doesn't Print!
return true;
}
return super.onKeyDown(keyCode, event);
}
Note, you CAN'T capture the Home key!
