MediaRecorder latency on Android

I'm experimenting with recording audio in a homebrew Android application, then immediately playing back the audio. I define an OnTouchListener for a button that waits for a MotionEvent. Recording happens if the ACTION_DOWN MotionEvent occurs for as long as the button is held; recording stops if the ACTION_UP MotionEvent occurs.

The problem is that recording doesn't happen exactly when the ACTION_DOWN event occurs, aka pressing the button. How can you design the action to start recording exactly when the button is pressed and the MediaRecorder is called to start?

I've searched through Stack Overflow and found other users with the same problem and no great solution. Is it even possible?

If you need code, I can provide.
