Class Overview

CameraAccessException is thrown if a camera device could not be queried or opened by the CameraManager, or if the connection to an opened CameraDevice is no longer valid.

Summary

Constants
int	CAMERA_DISABLED	The camera is disabled due to a device policy, and cannot be opened.
int	CAMERA_DISCONNECTED	The camera device is removable and has been disconnected from the Android device, or the camera id used with `openCamera(String, CameraDevice.StateListener, Handler)` is no longer valid, or the camera service has shut down the connection due to a higher-priority access request for the camera device.
int	CAMERA_ERROR	The camera device is currently in the error state.

Public Constructors
	CameraAccessException(int problem)
	CameraAccessException(int problem, String message)
	CameraAccessException(int problem, String message, Throwable cause)
	CameraAccessException(int problem, Throwable cause)

Public Methods
final int	getReason() The reason for the failure to access the camera.

Throwable	getCause() Returns the cause of this `Throwable`, or `null` if there is no cause.
String	getLocalizedMessage() Returns the detail message which was provided when this `Throwable` was created.
String	getMessage() Returns the detail message which was provided when this `Throwable` was created.
StackTraceElement[]	getStackTrace() Returns a clone of the array of stack trace elements of this `Throwable`.
final Throwable[]	getSuppressed() Returns the throwables suppressed by this.
Throwable	initCause(Throwable throwable) Initializes the cause of this `Throwable`.
void	printStackTrace(PrintStream err) Writes a printable representation of this `Throwable`'s stack trace to the given print stream.
void	printStackTrace(PrintWriter err) Writes a printable representation of this `Throwable`'s stack trace to the specified print writer.
void	printStackTrace() Writes a printable representation of this `Throwable`'s stack trace to the `System.err` stream.
void	setStackTrace(StackTraceElement[] trace) Sets the array of stack trace elements.
String	toString() Returns a string containing a concise, human-readable description of this object.

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Constants

public static final int CAMERA_DISABLED

The camera is disabled due to a device policy, and cannot be opened.

public static final int CAMERA_DISCONNECTED

The camera device is removable and has been disconnected from the Android device, or the camera id used with openCamera(String, CameraDevice.StateListener, Handler) is no longer valid, or the camera service has shut down the connection due to a higher-priority access request for the camera device.

Constant Value: 2 (0x00000002)

public static final int CAMERA_ERROR

The camera device is currently in the error state.

The camera has failed to open or has failed at a later time as a result of some non-user interaction. Refer to onError(CameraDevice, int) for the exact nature of the error.

No further calls to the camera will succeed. Clean up the camera with close() and try handling the error in order to successfully re-open the camera.
