Public methods

describeContents

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(android.os.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. Value is either 0 or CONTENTS_FILE_DESCRIPTOR

getAudioAttributes

public AudioAttributes getAudioAttributes ()

Get the audio attributes for this session. The attributes will affect volume handling for the session. When the volume type is PlaybackInfo#PLAYBACK_TYPE_REMOTE these may be ignored by the remote volume handler.

Returns
AudioAttributes The attributes for this session.

getCurrentVolume

public int getCurrentVolume ()

Get the current volume for this session.

Returns
int The current volume where this session is playing.

getMaxVolume

public int getMaxVolume ()

Get the maximum volume that may be set for this session.

Returns
int The maximum allowed volume where this session is playing.

getPlaybackType

public int getPlaybackType ()

Get the type of playback which affects volume handling. One of:

Returns
int The type of playback this session is using.

getVolumeControl

public int getVolumeControl ()

Get the type of volume control that can be used. One of:

Returns
int The type of volume control that may be used with this session.

getVolumeControlId

public String getVolumeControlId ()

Gets the volume control ID for this session. It can be used to identify which volume provider is used by the session.

When the session starts to use remote volume handling, a volume provider should be set and it may set the volume control ID of the provider if the session wants to inform which volume provider is used. It can be null if the session didn't set the volume control ID or it uses local playback.

Returns
String the volume control ID for this session or null if it uses local playback or not set.

toString

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

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. Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
