class
MediaSessionManager.RemoteUserInfo
extends Object
| java.lang.Object | |
| ↳ | android.media.session.MediaSessionManager.RemoteUserInfo |
Information of a remote user of MediaSession or MediaBrowserService.
This can be used to decide whether the remote user is trusted app, and also differentiate
caller of MediaSession and MediaBrowserService callbacks.
See equals(java.lang.Object) to take a look at how it differentiate media controller.

RemoteUserInfo
public RemoteUserInfo (String packageName, int pid, int uid)
Create a new remote user information.
| Parameters | |
|---|---|
packageName |
String: The package name of the remote user
This value cannot be null. |
pid |
int: The pid of the remote user |
uid |
int: The uid of the remote user |
Public methods
equals
public boolean equals (Object obj)
Returns equality of two RemoteUserInfo. Two RemoteUserInfo objects are equal if and only if they have the same package name, same pid, and same uid.
| Parameters | |
|---|---|
obj |
Object: the reference object with which to compare.
This value may be null. |
| Returns | |
|---|---|
boolean |
true if equals, false otherwise |
getPid
public int getPid ()
| Returns | |
|---|---|
int |
pid of the controller |
getUid
public int getUid ()
| Returns | |
|---|---|
int |
uid of the controller |
hashCode
public int hashCode ()
Returns a hash code value for the object. This method is
supported for the benefit of hash tables such as those provided by
HashMap.
The general contract of hashCode is:
- Whenever it is invoked on the same object more than once during
an execution of a Java application, the
hashCodemethod must consistently return the same integer, provided no information used inequalscomparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. - If two objects are equal according to the
equals(Object)method, then calling thehashCodemethod on each of the two objects must produce the same integer result. - It is not required that if two objects are unequal
according to the
equals(java.lang.Object)method, then calling thehashCodemethod on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
As much as is reasonably practical, the hashCode method defined by
class Object does return distinct integers for distinct
objects. (This is typically implemented by converting the internal
address of the object into an integer, but this implementation
technique is not required by the
Java™ programming language.)
