CarrierIdentifier


public class CarrierIdentifier
extends Object implements Parcelable

java.lang.Object
   ↳ android.service.carrier.CarrierIdentifier


Used to pass info to CarrierConfigService implementations so they can decide what values to return. Instead of passing mcc, mnc, gid1, gid2, spn, imsi to locate carrier information, CarrierIdentifier also include carrier id TelephonyManager#getSimCarrierId(), a platform-wide unique identifier for each carrier. CarrierConfigService can directly use carrier id as the key to look up the carrier info.

CarrierIdentifier

Added in API level 28
public CarrierIdentifier (byte[] mccMnc, 
                String gid1, 
                String gid2)

Creates a carrier identifier instance.

gid1 String: The group identifier level 1. This value may be null.

gid2 String: The group identifier level 2. This value may be null.

Throws
IllegalArgumentException If the length of mccMnc is not 3.

Public methods

describeContents

Added in API level 23
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

equals

Added in API level 23
public boolean equals (Object obj)

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.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
obj Object: the reference object with which to compare.

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

getCarrierId

Added in API level 29
public int getCarrierId ()

Returns the carrier id.

Returns
int

getGid1

Added in API level 23
public String getGid1 ()

Get the group identifier level 1.

Returns
String This value may be null.

getGid2

Added in API level 23
public String getGid2 ()

Get the group identifier level 2.

Returns
String This value may be null.

getImsi

Added in API level 23
public String getImsi ()

Get the international mobile subscriber identity.

Returns
String This value may be null.

getMcc

Added in API level 23
public String getMcc ()

Get the mobile country code.

Returns
String

getMnc

Added in API level 23
public String getMnc ()

Get the mobile network code.

Returns
String

getSpecificCarrierId

Added in API level 29
public int getSpecificCarrierId ()

A specific carrier ID returns the fine-grained carrier ID of the current subscription. It can represent the fact that a carrier may be in effect an aggregation of other carriers (ie in an MVNO type scenario) where each of these specific carriers which are used to make up the actual carrier service may have different carrier configurations. A specific carrier ID could also be used, for example, in a scenario where a carrier requires different carrier configuration for different service offering such as a prepaid plan.

Returns
int

getSpn

Added in API level 23
public String getSpn ()

Get the service provider name.

Returns
String This value may be null.

hashCode

Added in API level 23
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 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 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 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.

Returns
int a hash code value for this object.

toString

Added in API level 23
public String toString ()

Returns a string representation of the object.

Returns
String a string representation of the object.

writeToParcel

Added in API level 23
public 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. This value cannot be null.

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
