CameraInstance §

= a handler class used to deal with the camera2 api

Methods §

• openCamera()

  • initiates the camera

• setUpCameraOutputs()

  • iterates over cameraDevices (cameraIdList)
  • checks preview sizes → chooseOptimalSize() → mPreviewSize

• chooseOptimalSize()

  • chooses the biggest possible size from a given array of sizes

Variables §

• mPreviewSize: biggest possible preview size

Sequence §

1. SurfaceTextureListener
   1. onSurfaceTextureAvailable → openCamera()
   2. onSurfaceTextureChanged → configureTransform()
2. openCamera()
   1. setUpCameraOutputs()
   2. manager.openCamera → mStateCallback
3. mStateCallback
   1. onOpened → createCameraPreviewSession()
   2. else → close cameraDevice (and finish activity)
4. createCameraPreviewSession()
   1. mPreviewRequestBuilder
   2. createCaptureSession() → captureSessionStateCallback
5. captureSessionStateCallback
   1. onConfigured → configure mPreviewRequestBuilder
