If you are using P 2.0a4, make sure to download
Ketai v 4 from http://code.google.com/p/ketai/downloads/list
Use the example code for the camera included in the zip file.
The Android SDK requirements for Processing 2.0a4 are documented here, http://wiki.processing.org/w/Android. Make sure to update your SDK/API accordingly.

Yes, I already did all of that.

Also so I can run it I had to do a new folder "code" in the sketch folder and put there the Ketai.jar.

And erase the 2 lines cam.list() and numberOfCameras = cam.getNumberOfCameras()

Then the app runs but the error I get is that one, the first I mentioned.

And I get in my phone the next message CameraGettingStarted(process changethispackage.beforesubmitting.tothemarket.cameragettingstarted) have stopped.

It's the problem processing or my phone (sony ericcson xperia x8).

Hello Diana,

What version of android is your mobile running? v4 of Ketai requires Android 2.3.4.

What is the printout on the console when the library loads?

Some mobiles handle cameras differently.

thanks,

Hey CG,

I have Android 2.1.

I talk to Andrew, the author of this mobile app https://market.android.com/details?id=processing.android.test.toniayourself02

And he told me, he did it on Processing 1.5.1, I'm starting to believe that's the problem. And I cannot use that version because of some issue with the build.xml.

The error I get:

KetaiCamera found onCameraPreviewEvent in parent...
KetaiCamera did not find onCameraPreviewEvent for Image Method: onCameraPreviewEvent
KetaiCamera completed instantiation...
