1.     We are trying to implement applications which makes use of longpress events. However, our tests show that down-key event and up-key events are generated simultaneously when key is released. The system must send us down-key event upon touch and up-event upon release in order for us to implement long-press. Is there a way to do this?

2.     We are trying to generate system tone (beep) upon key-press. The reason for wanting to use the system-level tone is for performance reasons. We don’t want to have to play a media file every time upon touch. Is there a way to use system tones?
