| static

Resources are occupied, and cannot be reused.

## ◆ ERR_ABORTED

final int io.agora.rtc2.Constants.ERR_ABORTED = 20

| static

The Token expired due to one of the following reasons:

1. Authorized Timestamp expired: The timestamp is represented by the number of seconds elapsed since 1/1/1970. The user can use the Token to access the Agora service within five minutes after the Token is generated. If the user does not access the Agora service after five minutes, this Token will no longer be valid.
2. Call Expiration Timestamp expired: The timestamp indicates the exact time when a user can no longer use the Agora service (for example, when a user is forced to leave an ongoing call). When the value is set for the Call Expiration Timestamp, it does not mean that the Dynamic Key will be expired, but that the user will be kicked out of the channel.</il>

## ◆ ERR_INVALID_TOKEN
