本文详细介绍如何从零开始构建一个Android平台上的相机应用程序。包括检测并访问摄像头、创建预览类、构建预览布局、设置捕获监听器、实现图片及视频的捕获与保存以及正确释放摄像头资源等关键步骤。

Detect and Access Camera - Create code to check for the existence of cameras and request access.
Create a Preview Class - Create a camera preview class that extends SurfaceView and implements theSurfaceHolder interface. This class previews the live images from the camera.
Build a Preview Layout - Once you have the camera preview class, create a view layout that incorporates the preview and the user interface controls you want.
Setup Listeners for Capture - Connect listeners for your interface controls to start image or video capture in response to user actions, such as pressing a button.
Capture and Save Files - Setup the code for capturing pictures or videos and saving the output.
Release the Camera - After using the camera, your application must properly release it for use by other applications.
