AdId
public
class
AdId
extends Object
java.lang.Object | |
↳ | android.adservices.adid.AdId |
A unique, user-resettable, device-wide, per-profile ID for advertising.
Ad networks may use AdId
to monetize for Interest Based Advertising (IBA), i.e.
targeting and remarketing ads. The user may limit availability of this identifier.

Constants
ZERO_OUT
public static final String ZERO_OUT
A zeroed-out ad id
that is returned when the user has limited ad tracking
.
Constant Value: "00000000-0000-0000-0000-000000000000"
Public constructors

limitAdTrackingEnabled |
boolean : value from the provider service which determines the value of
adId. |
Public methods
equals
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 returntrue
. - It is symmetric: for any non-null reference values
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons on the objects is modified. - For any non-null reference value
x
,x.equals(null)
should returnfalse
.
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. |
getAdId
public String getAdId ()
The advertising ID.
The value of advertising Id depends on a combination of isLimitAdTrackingEnabled()
and AdServicesPermissions.ACCESS_ADSERVICES_AD_ID
.
When the user is limiting ad tracking
, the API returns
ZERO_OUT
. This disallows a caller to track the user for monetization purposes.
Otherwise, a string unique to the device and user is returned, which can be used to track users for advertising.
Returns | |
---|---|
String |
This value cannot be null . |
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
hashCode
method must consistently return the same integer, provided no information used inequals
comparisons 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 thehashCode
method 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 thehashCode
method 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. (The hashCode may or may not be implemented
as some function of an object's memory address at some point
in time.)
Returns | |
---|---|
int |
a hash code value for this object. |
isLimitAdTrackingEnabled
public boolean isLimitAdTrackingEnabled ()
Retrieves the limit ad tracking enabled setting.
This value is true if user has limit ad tracking enabled, false
otherwise.
Returns | |
---|---|
boolean |
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())
