Thank you!!!!

It finally worked! I had to do it like you said exactlly.. in my case:

if(mCamera!=null){

mPreviewRunning = false;

mCamera.stopPreview();

mCamera.setPreviewCallback(null);

mCamera.release();

mCamera=null;

}

works fine now.. I'm in the other activity with no crashes ;)

Thanks

I also find the "Method called after release()" occasionally in my
camera app's crash logs with end users, and have thus far not been
able to track it down because I did not encounter it on my own phones
(ADP1 with Android 1.6 and HTC Desire with Android 2.2). Apparently
something camera related in android.hardware.Camera sometimes lives on
even after releasing the camera, or I overlooked something in doing a
"join" when cleaning up. Difficult to debug. You can try inserting
mCamera.setPreviewCallback(null) in between mCamera.stopPreview() and
mCamera.release(), ending it all with setting mCamera=null and
wrapping everything in a mCamera!=null check and see if that works for
you.

No ideias for this?

I just keep reading on google to release the camera.. and I've just  

done that but I get the error anyway..

Hi, I'm getting this error ( in the end of this post)... which I guess

I understand it's because I'm calling something after releasing it..

but I can't find a wy to work it around... Here is the method:

public void surfaceDestroyed(SurfaceHolder holder) {

           mPreviewRunning = false;

           mCamera.stopPreview();

           mCamera.release();

   }

I've tried all combinations.. I've tried:

mCamera.setPreviewCallback(null);

This class, where the surfaceview is implemented can be accessed by 2

different classes.. one that doesnt implement surfaceview and other

that does.. the error just shows me when I go from the activity that

uses the camera to the activity that also uses camera.. I don't know

what else to do.. I've google it and can't find any answer. any

suggestion?
