CWAC Camera - Overriding saveImage()

Question

I'm trying to use my own custom implementation of CWAC Camera. I am trying to override the saveImage function on my own extension of the SimpleCameraHost. This is my code:

You are welcome to override saveImage(byte[]) and do something else with the byte[], such as send it over the Internet. saveImage(byte[]) is called on a background thread, so you do not have to do your own asynchronous work.

@Override
public void saveImage(byte[] byteArray) {
    Intent myIntent = new Intent();
    retData.putExtra("data", byteArray);
    getActivity().setResult(Activity.RESULT_OK, myIntent);
    getActivity().finish();
}

I'm testing this on a samsung galaxy S3, and it works perfectly, but when I try to use the front facing camera, my application freezes up and crashes. I'm not doing anything onActivityResult, so it is originating from the CameraFragment. Don't know what could be wrong because the documentation says that it has been tested with an S3.

EDIT #2:

@Override
public Size getPictureSize(Parameters parameters) {

        //return CameraUtils.getLargestPictureSize(parameters);
        // TODO Auto-generated method stub
        List<Camera.Size> list = parameters.getSupportedPictureSizes();
        int targetWidth = 1280;
        int width;
        Camera.Size optimalSize= null;
        for (Camera.Size size : list) {
            width = size.width;
            if (width==targetWidth) {
                optimalSize = size;
                return optimalSize;
            } else if (width<targetWidth){
                optimalSize = size;
                return optimalSize;
            } else if (width>targetWidth) {
                optimalSize = size;
            }
        }

        return optimalSize;

}

Okay, so my code definitely works for passing this through for the back camera. When I try the front facing camera, I still get a crash. If this was a binder error wouldn't I get !!! FAILED BINDER TRANSACTION !!!

Answer 1

I'm testing this on a samsung galaxy S3, and it works perfectly, but when I try to use the front facing camera, my application freezes up and crashes.

In the future, use LogCat to examine the Java stack trace with your crash.

In this case, my guess is that it is because you are trying to pass a multi-MB image file in an Intent extra, which will not work. Either use the image in the same activity where you take it, or pass it using other means (e.g., a careful handoff via a static data member).

Don't know what could be wrong because the documentation says that it has been tested with an S3.

And if you doubt this, try not overriding saveImage(), and see what happens.
