setOneShotPreviewCallback not hitting onPreviewFrame() in callback

Question

I\'m creating a video capture activity for an app I\'m making, and I want to capture a preview frame as well to use as a playback button. I\'ve set the SurfaceView

Answer 1

mCamera.unlock() detaches the camera from the process. It's necessary to call:

mCamera.reconnect();

before calling:

mCamera.setOneShotPreviewCallback(mPreviewCallback);

(but after everything else).
