Camera app stopped working when upgrading from Android 4.0.4 to 4.1.2

Question

I’m new with the platform and I’m having trouble in an app I’m developing, it was working normally on Android 4.0.4 and now that I upgraded to 4.1.2 the following message is displayed:

02-27 10:14:47.923: E/Camera_ControlThread(156): Taking picture when recording is not supported!

Soon after the update the following items stopped working:

• Start camera with Camera.open();
• Configuration of params;
• Call to takepicture(null, null, mPicture);

I don’t use the surfaceview, because the app takes pictures in real time.

the code is this

Camera camera;
public Cam cam;

protected void onCreate(){
cam = new Cam();
camera  = cam.getCameraInstance(getApplicationContext(), cam.idCameraFrontal());
}

PictureCallback jpeg = new PictureCallback() {

    @Override
    public void onPictureTaken(byte[] data, Camera camera) {
        new ThreadProcessamento(data);
        processando = true;
    }
};


  public class ThreadFoto implements Runnable{
    Thread t;

    public ThreadFoto(){
        t = new Thread(this,"video");
        t.setPriority(10);
        t.start();
    }

    public void run(){
        sairThread = false;
        int count = 0;
        do{
            if(cam.checkCameraHardware(getApplicationContext())){
                try{
                    if(!processando && !bCapturar){//!processando && 
                        camera.takePicture(null, null, jpeg);
                    }
                }catch(Exception e){
                    Log.v("ri","ThreadFoto.Exception:"+e.getMessage());
                }
                log = "Foto tirada: "+count;
            }else{
                log = "Hardware desativado:"+count;
            }
            try {
                Thread.sleep(200);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            ihc.update();
            count++;
        }while(!sairThread);
    }
}

Sometimes the problem is not the code, but the firmware installation. I solved an identical problem simply giving a 'factory reset' it will remain android 4.1.2 but eliminate all apps, configs and remains of the installation. In my case it worked!
