| ↳ | android.hardware.usb.UsbAccessory |
A class representing a USB accessory, which is an external hardware component that communicates with an android application over USB. The accessory is the USB host and android the device side of the USB connection.
When the accessory connects, it reports its manufacturer and model names, the version of the accessory, and a user visible description of the accessory to the device. The manufacturer, model and version strings are used by the USB Manager to choose an appropriate application for the accessory. The accessory may optionally provide a unique serial number and a URL to for the accessory's website to the device as well.
An instance of this class is sent to the application via the
ACTION_USB_ACCESSORY_ATTACHED Intent.
The application can then call openAccessory(UsbAccessory) to open a file descriptor
for reading and writing data to and from the accessory.
For more information about communicating with USB hardware, read the USB developer guide.

Describe the kinds of special objects contained in this Parcelable's marshalled representation.
Compares this instance with the specified object and indicates if they
are equal. In order to be equal, o must represent the same object
as this instance using a class-specific comparison. The general contract
is that this comparison should be reflexive, symmetric, and transitive.
Also, no object reference other than null is equal to null.
The default implementation returns true only if this ==
o. See Writing a correct
equals method
if you intend implementing your own equals method.
The general contract for the equals and hashCode() methods is that if equals returns true for
any two objects, then hashCode() must return the same value for
these objects. This means that subclasses of Object usually
override either both methods or neither of them.

true if the specified object is equal to this Object; false otherwise.Returns a user visible description of the accessory.
Returns the manufacturer name of the accessory.
Returns the model name of the accessory.
Returns the unique serial number for the accessory. This is an optional serial number that can be used to differentiate between individual accessories of the same model and manufacturer
Returns the URI for the accessory. This is an optional URI that might show information about the accessory or provide the option to download an application for the accessory
Returns the version of the accessory.
Returns an integer hash code for this object. By contract, any two
objects for which equals(Object) returns true must return
the same hash code value. This means that subclasses of Object
usually override both methods or neither method.
Note that hash values must not change over time unless information used in equals comparisons also changes.
See Writing a correct
hashCode method
if you intend implementing your own hashCode method.
Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:
getClass().getName() + '@' + Integer.toHexString(hashCode())

toString method
if you intend implementing your own toString method.
