DisconnectCause


public final class DisconnectCause
extends Object implements Parcelable

java.lang.Object
   ↳ android.telecom.DisconnectCause


Describes the cause of a disconnected call. This always includes a code describing the generic cause of the disconnect. Optionally, it may include a label and/or description to display to the user. It is the responsibility of the ConnectionService to provide localized versions of the label and description. It also may contain a reason for the disconnect, which is intended for logging and not for display to the user.

Summary

Constants

int ANSWERED_ELSEWHERE

Disconnected because the user did not locally answer the incoming call, but it was answered on another device where the call was ringing.

int BUSY

Disconnected because the other party was busy.

int CALL_PULLED

Disconnected because the call was pulled from the current device to another device.

int CANCELED

Disconnected because it has been canceled.

int CONNECTION_MANAGER_NOT_SUPPORTED

Disconnected because the connection manager did not support the call.

int ERROR

Disconnected because there was an error, such as a problem with the network.

int LOCAL

Disconnected because of a local user-initiated action, such as hanging up.

int MISSED

Disconnected because there was no response to an incoming call.

int OTHER

Disconnected for reason not described by other disconnect codes.

String REASON_EMERGENCY_CALL_PLACED

This reason is set when a call is ended in order to place an emergency call when a PhoneAccount doesn't support holding an ongoing call to place an emergency call.

String REASON_EMULATING_SINGLE_CALL

Reason code (returned via getReason()), which indicates that the connection service is setting the call's state to Call#STATE_DISCONNECTED because it is internally changing the representation of an IMS conference call to simulate a single-party call.

String REASON_IMS_ACCESS_BLOCKED

Reason code (returned via getReason()), which indicates that the call was disconnected because IMS access is blocked.

String REASON_WIFI_ON_BUT_WFC_OFF

Reason code (returned via getReason()) which indicates that a call could not be completed because the cellular radio is off or out of service, the device is connected to a wifi network, but the user has not enabled wifi calling.

int REJECTED

Disconnected because the user rejected an incoming call.

int REMOTE

Disconnected because the remote party hung up an ongoing call, or because an outgoing call was not answered by the remote party.

int RESTRICTED

Disconnected because of a restriction on placing the call, such as dialing in airplane mode.

int UNKNOWN

Disconnected because of an unknown or unspecified reason.

Inherited constants

int CONTENTS_FILE_DESCRIPTOR

Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor.

int PARCELABLE_WRITE_RETURN_VALUE

Flag for use with writeToParcel(Parcel, int): the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)".

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 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 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
o Object: the reference object with which to compare.

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

getCode

Added in API level 23
public int getCode ()

Returns the code for the reason for this disconnect.

Returns
int The disconnect code.

getDescription

Added in API level 23
public CharSequence getDescription ()

Returns a description which explains the reason for the disconnect cause and is for display in the user interface. This optional text is generally a longer and more descriptive version of getLabel(), however it can exist even if getLabel() is empty. The In-Call UI should display this relatively prominently; the traditional implementation displays this as an alert dialog. The ConnectionService is responsible for providing and localizing this message. If there is no string provided, returns null.

Returns
CharSequence The disconnect description.

getLabel

Added in API level 23
public CharSequence getLabel ()

Returns a short label which explains the reason for the disconnect cause and is for display in the user interface. If not null, it is expected that the In-Call UI should display this text where it would normally display the call state ("Dialing", "Disconnected") and is therefore expected to be relatively small. The ConnectionService is responsible for providing and localizing this label. If there is no string provided, returns null.

Returns
CharSequence The disconnect label.

getReason

Added in API level 23
public String getReason ()

Returns an explanation of the reason for the disconnect. This is not intended for display to the user and is used mainly for logging.

Returns
String The disconnect reason.

getTone

Added in API level 23
public int getTone ()

Returns the tone to play when disconnected.

Returns
int the tone as defined in ToneGenerator to play when disconnected.

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 destination, 
                int flags)

Flatten this object in to a Parcel.

Parameters
destination 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
