• Contents of onResume to onCreate
• Contents of onPause to onDestroy

Case of normal plug-in

• Completion by itself
• Initialization with onResume
• Terminate processing with onPause

Case of Connecting with Another Plug-in

• Avoid influencing the shooting application as much as possible. When linking with another plug-in, call onStop with startActivityForResult
• Make sure to terminate the plug-in with the long press of the mode button
• Do not perform background processing at onPause()
• Terminate HandlerThread

Camera.Parameters.set("RIC_SHOOTING_MODE", "RicMoviePreview1024");

When using the THETA Microphone

AudioManager.setParameters("RicUseBFormat=false");
