Java Question [Solved] PreviewCallback

[Johan Schoeman]

I have this code in a wrapper but the PreviewCallback does not get fired:

        PreviewCallback mPreviewCallback = new PreviewCallback() {
           
            @Override
            public void onPreviewFrame(byte[] data, Camera camera) {
            BA.Log("In onPreviewFrame");       
                processImage(data);

            }
        };

I do have
import android.hardware.Camera.PreviewCallback;
in the wrapper. No compiling error - it just won't fire.

Some pointers will be much appreciated.

and you added the
mPreviewCallback
to the wrapped object in some way?

myobject.addpreviewcallback(mPreviewCallback);

?

The callback should come from android.harware.Camera...? I imported Andoid.hardware.Camera.PreviewCallback. Should that not then raise the callback?

I do have....

mCamera.setPreviewCallback(mPreviewCallback);

...in the wrapper in some places where it is required but it does not fire...
