Returns
long The last time the position was updated.

getPlaybackSpeed

long getPosition ()

Get the current playback position in ms.

Returns
long

getState

Added in API level 21

Returns
int

toString

Added in API level 21
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.
