Based on the help for getSupportedPreviewFormats [1], NV21 should be
always supported. However, when I run
camParam = mCamera.getParameters();
camParam.setPictureFormat(ImageFormat.NV21);
mCamera.setParameters(camParam);
on my nexus 4, I get an error setParameters failed. The only way to
get
found online.
I wasn't aware of Build.VERSION.SDK_INT. It is definitely the
better way to go.
thanks a lot

I'd like to get some advice on optimizing file IO of a camera-frame

I used the setPreviewCallbackWithBuffer() method to capture each
preview frame and do some processing in the real-time. The processed

I need to let the camera to focus to a user supplied

to inquire the focus distance, but not one to set the
focus distance manually.
Can someone give me a hint how to achieve this?
