Ketai camera not working

Hi everyone!

I'm having a really hard time with the ketai camera library. I can't see any image.

I get to run the CameraGettingStarted example without any problem. The log doesn't show any errors and I can switch the flash of my phone on and off by touching the "menu" button (as intended).

The Processing console doesn't show any errors and it even shows this:
1. default imageformat:17
2. supported flashmode: on
3. supported flashmode: torch
4. supported flashmode: off
5. supported flashmode: auto
6. Requested camera parameters as (w,h,fps):640,480,24

which suggests (i think) that the sketch and the camera are in communication. I just can't figure out why I can't see any image on the screen.
Here's the code:
2. /**
3. * Ketai Sensor Library for Android: http://KetaiProject.org
4. *
5. * Ketai Camera Features:
6. * <ul>
7. * <li>Interface for built-in camera</li>
8. * <li></li>
9. * </ul>

13. import ketai.camera.*;
15. KetaiCamera cam;
17. void setup() {
18. orientation(LANDSCAPE);
19. imageMode(CENTER);
20. cam = new KetaiCamera(this, 320, 240, 24);
21. }
23. void draw() {
24. image(cam, width/2, height/2);
25. }
27. void onPause()
28. {
29. super.onPause();
30. //Make sure to releae the camera when we go
31. // to sleep otherwise it stays locked
32. if (cam != null && cam.isStarted())
33. cam.stop();
34. }
36. void onCameraPreviewEvent()
37. {
38. cam.read();
39. }
41. void exit() {
42. cam.stop();
43. }
45. // start/stop camera preview by tapping the screen
46. void mousePressed()
47. {
48. if (cam.isStarted())
49. {
50. cam.stop();
51. }
52. else
53. cam.start();
54. }
55. void keyPressed() {
56. if (key == CODED) {
57. if (keyCode == MENU) {
58. if (cam.isFlashEnabled())
59. cam.disableFlash();
60. else
61. cam.enableFlash();
62. }
63. }
64. }
I'm on OSX and using a Huawei Ascend P6 running android 4.2.2 as testing device.

Please guys! Help!
