Fields

CREATOR

added in API level 21
public static final Creator<MediaDescription> CREATOR

Public methods

describeContents

added in API level 21
public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance.

equals

added in API level 21
public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Parameters
o Object: the reference object with which to compare.

Returns
boolean true if this object is the same as the obj argument; false otherwise.

getDescription

added in API level 21
public CharSequence getDescription ()

Returns a description suitable for display or null.

Returns
CharSequence A description or null.

getExtras

added in API level 21
public Bundle getExtras ()

Returns any extras that were added to the description.

Returns
Bundle A bundle of extras or null.

getIconBitmap

added in API level 21
public Bitmap getIconBitmap ()

Returns a bitmap icon suitable for display or null.

Returns
Bitmap An icon or null.

getIconUri

added in API level 21
public Uri getIconUri ()

Returns a Uri for an icon suitable for display or null.

Returns
Uri An icon uri or null.

getMediaId

added in API level 21
public String getMediaId ()

Returns the media id or null. See MediaMetadata.METADATA_KEY_MEDIA_ID.

Returns
String

This value may be null.

getMediaUri

added in API level 23
public Uri getMediaUri ()

Returns a Uri representing this content or null.

Returns
Uri A media Uri or null.

getSubtitle

added in API level 21
public CharSequence getSubtitle ()

Returns a subtitle suitable for display or null.

Returns
CharSequence A subtitle or null.

getTitle

added in API level 21
public CharSequence getTitle ()

Returns a title suitable for display or null.

Returns
CharSequence A title or null.

toString

added in API level 21
public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Returns
String a string representation of the object.

writeToParcel

added in API level 21
public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
dest Parcel: The Parcel in which the object should be written.

flags int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE.
