CameraView will log a lot of interesting events related to the camera lifecycle. These are important to identify bugs. The default logger will simply use Android Log methods posting to logcat.

You can attach and detach external loggers using CameraLogger.registerLogger():

CameraLogger.registerLogger(new Logger() {
    public void log(@LogLevel int level, String tag, String message, @Nullable Throwable throwable) {
        // For example...

Make sure you enable the logger using CameraLogger.setLogLevel(@LogLevel int). The default will only log error events.
