PhoneAccountHandle

public final class PhoneAccountHandle
extends Object implements Parcelable

java.lang.Object
   ↳ android.telecom.PhoneAccountHandle


The unique identifier for a PhoneAccount. A PhoneAccountHandle is made of two parts:

  • The component name of the associated connection service.
  • A string identifier that is unique across PhoneAccountHandles with the same component name.
Note: This Class requires a non-null ComponentName and UserHandle to operate properly. Passing in invalid parameters will generate a log warning. See PhoneAccount, TelecomManager.

CREATOR

added in API level 23
Creator<PhoneAccountHandle> CREATOR

Public constructors

PhoneAccountHandle

added in API level 23
PhoneAccountHandle (ComponentName componentName, 
                String id)

Parameters
componentName ComponentName

This value must never be null.

id String

This value must never be null.

PhoneAccountHandle

added in API level 23
PhoneAccountHandle (ComponentName componentName, 
                String id, 
                UserHandle userHandle)

Parameters
componentName ComponentName

This value must never be null.

id String

This value must never be null.

userHandle UserHandle

This value must never be null.

Public methods

describeContents

added in API level 23
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 23
boolean equals (Object other)

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
other Object: the reference object with which to compare.

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

getComponentName

added in API level 23
ComponentName getComponentName ()

The ComponentName of the connection service which is responsible for making phone calls using this PhoneAccountHandle.

Returns
ComponentName A suitable ComponentName.

getId

added in API level 23
String getId ()

A string that uniquely distinguishes this particular PhoneAccountHandle from all the others supported by the connection service that created it.

A connection service must select identifiers that are stable for the lifetime of their users' relationship with their service, across many Android devices. For example, a good set of identifiers might be the email addresses with which with users registered for their accounts with a particular service. Depending on how a service chooses to operate, a bad set of identifiers might be an increasing series of integers (0, 1, 2, ...) that are generated locally on each phone and could collide with values generated on other phones or after a data wipe of a given phone. Important: A non-unique identifier could cause non-deterministic call-log backup/restore behavior.

Returns
String A service-specific unique identifier for this PhoneAccountHandle.

getUserHandle

added in API level 23
UserHandle getUserHandle ()

Returns
UserHandle the UserHandle to use when connecting to this PhoneAccount.

hashCode

added in API level 23
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 in equals 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 the hashCode 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 the hashCode 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. (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.)

Returns
int a hash code value for this object.

toString

added in API level 23
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 23
void writeToParcel (Parcel out, 
                int flags)

Flatten this object in to a Parcel.

Parameters
out 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_WRITE_RETURN_VALUE.
