Error Handling

When you make an API call to access an HMS SDK, the SDK may return error codes. ErrorCodes are returned when a problem that cannot be recovered without app intervention has occurred.

These are returned as HMSException in the onError callback of the HMSUpdateListner.

Following are the different error codes that are returned by the SDK . Before returning any error code, SDK retries the errors(whichever is possible).
