Description
Take a picture.
This function must be called while preview is active, that is Camera.start() has been called.
If it returns true, then the platform will asynchronously take a picture from the Camera (eventually using flash) then call Camera.onEvent callback one or more times.

- a number, indicating the type of event
- a data buffer (string) depending on the event type
Event types are:
- 0: shutter sound is triggered, data is empty (if supported)
- 1: uncompressed image ready, data contains the uncompressed image (android only, optional)
- 2: jpeg image ready, data contains jpeg image. This event is always fired if takePicture() was successful
