Interface ErrorHandler

public interface ErrorHandler

An interface to define a way to handle camera errors.

Because most of the Camera3 code is asynchronous, exceptions can't always be thrown to the user. This interface provides a channel for Camera3 to send error messages back to the caller so that they can be displayed to the user.

For debugging, you can use Camera3.ERROR_HANDLER_DEFAULT, which just logs everything.

Method Summary

Modifier and Type	Method and Description
void	error(java.lang.String message, java.lang.Exception e) Called when a fatal error occurred that definitely prevented the camera form working in a way that is visible to the user.
void	info(java.lang.String message) Called throughout the Camera3 code for debugging.
void	warning(java.lang.String message) Called when we suspect that the user might have made a mistake or when minor error occurred that might alter the behavior of the camera.

           @Nullable

void warning(java.lang.String message)

Called when we suspect that the user might have made a mistake or when minor error occurred that might alter the behavior of the camera.

void info(java.lang.String message)
