CallException | API reference | Android Developers

public final class CallException
extends RuntimeException implements Parcelable

java.lang.Object
↳	java.lang.Throwable
	↳	java.lang.Exception
		↳	java.lang.RuntimeException
			↳	android.telecom.CallException

This class defines exceptions that can be thrown when using Telecom APIs with OutcomeReceivers. Most of these exceptions are thrown when changing a call state with CallControls or CallControlCallbacks.

Summary

Constants
`int`	`CODE_CALL_CANNOT_BE_SET_TO_ACTIVE` The operation has failed because Telecom cannot set the requested call as the current active call.
`int`	`CODE_CALL_IS_NOT_BEING_TRACKED` The operation has failed because Telecom has already removed the call from the server side and destroyed all the objects associated with it.
`int`	`CODE_CALL_NOT_PERMITTED_AT_PRESENT_TIME` The operation has failed because there is either no PhoneAccount registered with Telecom for the given operation, or the limit of calls has been reached.
`int`	`CODE_CANNOT_HOLD_CURRENT_ACTIVE_CALL` The operation has failed due to Telecom failing to hold the current active call for the call attempting to become the new active call.
`int`	`CODE_ERROR_UNKNOWN` The operation has failed due to an unknown or unspecified error.
`int`	`CODE_OPERATION_TIMED_OUT` The operation has failed because the operation failed to complete before the timeout

Inherited constants

Constants

CODE_CALL_CANNOT_BE_SET_TO_ACTIVE

public static final int CODE_CALL_CANNOT_BE_SET_TO_ACTIVE

The operation has failed because Telecom cannot set the requested call as the current active call. The client should end the current active call and re-try the operation.

Constant Value: 4 (0x00000004)

CODE_CALL_IS_NOT_BEING_TRACKED

public static final int CODE_CALL_IS_NOT_BEING_TRACKED

The operation has failed because Telecom has already removed the call from the server side and destroyed all the objects associated with it. The client should re-add the call.

Constant Value: 3 (0x00000003)

CODE_CALL_NOT_PERMITTED_AT_PRESENT_TIME

public static final int CODE_CALL_NOT_PERMITTED_AT_PRESENT_TIME

The operation has failed because there is either no PhoneAccount registered with Telecom for the given operation, or the limit of calls has been reached. The client should end the current active call and re-try the failed operation.

Constant Value: 5 (0x00000005)

CODE_CANNOT_HOLD_CURRENT_ACTIVE_CALL

public static final int CODE_CANNOT_HOLD_CURRENT_ACTIVE_CALL

The operation has failed due to Telecom failing to hold the current active call for the call attempting to become the new active call. The client should end the current active call and re-try the failed operation.

Constant Value: 2 (0x00000002)

CODE_ERROR_UNKNOWN

public static final int CODE_ERROR_UNKNOWN

The operation has failed due to an unknown or unspecified error.

Constant Value: 1 (0x00000001)

CODE_OPERATION_TIMED_OUT

public static final int CODE_OPERATION_TIMED_OUT

The operation has failed because the operation failed to complete before the timeout

Constant Value: 6 (0x00000006)

Fields

CREATOR

public static final Creator<CallException> CREATOR

Responsible for creating CallAttribute objects for deserialized Parcels.

Public constructors

Public methods

describeContents

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`
