Android camera freeze issue

I have implemented a custom camera application. I have followed the steps explained in this tutorial.

On some devices, on taking a picture, my application freezes.

I get the following error message in logcat. 

E/V4LCameraAdapter(2321): hardware/amlogic/camera/V4LCameraAdapter/V4LCameraAdapter.cpp:834 GetFrame - GetFrame: No buff for Dequeue

E/V4LCameraAdapter(2321): hardware/amlogic/camera/V4LCameraAdapter/V4LCameraAdapter.cpp:993 previewThread - Preview thread get frame fail, need sleep:33333

Is the error specific to the hardware of the device? Is there a way to set the camera parameter from SDK to avoid No buff error?

Figured out the problem.

Apparently this call back was choking the buffers with the data for each frame of the camera preview. 

camera.setPreviewCallback(new PreviewCallback() {
      public void onPreviewFrame(byte[] data, Camera arg1) {
    //invalidate surfaceview
}
 });

Removing the callback worked for me.
