setupModules
provideOneCameraManager
调用Camera2OneCameraManagerImpl的create方法来获得一个OneCameraManager对象
new Captpre2OneCameraOpenerImpl
6:
Camera StartPreview
CameraActivity
registerPhotoModule
8:
newCaptureModule
通过cameraManager进入Framwork层

onSurfaceTextureAvailiable
当SurfaceTexture的状态变成可用的时候，会调用reopenCamera()方法来打开Camera，分析reopenCamera()方法:
mPreviewStatusListener=new PreviewStatusListener
调用Camera2OneCameraOpenerImpl的create方法来获得一个OneCameraOpener对象
GenericOneCameraImpl
CameraManager
开始预览
openCameraANdStartPreview
Captpre2OneCameraOpenerImpl
3:
mCurrentModule.init
1、获取第一步中创建的OneCameraOpener 和OneCameraManager对象2、新建CaptureModule的UI3、设置预览状态的监听4、获取SurfaceTexture

Captpre2OneCameraManagerImpl
reopenCamera
注册PhotoModule的关键还是在moduleManager.registerModule中的ModuleController createModule方法;来判断是进行拍照模块的注册还是Photo模块的注册
new Captpre2OneCameraManagerImpl
mCameraManager openCamera

进行初始化:先获取前面创建的OneCameraOpener对象以及OneCameraManager对象，然后再设置预览状态监听，这里主要分析预览状态的监听
onCreateTask：①初始化mOneCameraOpener对象和mOneCameraManager 对象②设置模块信息③进行初始化

根据配置信息，进行一系列模块的注册：Photo、闪光、广角、聚焦、有色分离等模块，这里只看photoModule注册
