extends HttpException

java.lang.Object

Known direct subclasses

QuicException

QuicException Subclass of NetworkException which contains a detailed QUIC error code from QuicErrorCode.

Exception passed to UrlRequest.Callback.onFailed() when the HTTP stack fails to process a network request. In this case getErrorCode() can be used to get more information about the specific type of failure.

Summary

Constants
`int`	`ERROR_ADDRESS_UNREACHABLE` Error code indicating the IP address being contacted is unreachable, meaning there is no route to the specified host or network.
`int`	`ERROR_CONNECTION_CLOSED` Error code indicating the connection was closed unexpectedly.
`int`	`ERROR_CONNECTION_REFUSED` Error code indicating the connection attempt was refused.
`int`	`ERROR_CONNECTION_RESET` Error code indicating the connection was unexpectedly reset.
`int`	`ERROR_CONNECTION_TIMED_OUT` Error code indicating the connection attempt timed out.
`int`	`ERROR_HOSTNAME_NOT_RESOLVED` Error code indicating the host being sent the request could not be resolved to an IP address.
`int`	`ERROR_INTERNET_DISCONNECTED` Error code indicating the device was not connected to any network.
`int`	`ERROR_NETWORK_CHANGED` Error code indicating that as the request was processed the network configuration changed.
`int`	`ERROR_OTHER` Error code indicating another type of error was encountered.
`int`	`ERROR_QUIC_PROTOCOL_FAILED` Error code indicating an error related to the QUIC protocol.
`int`	`ERROR_TIMED_OUT` Error code indicating a timeout expired.

Public constructors
`NetworkException(String message, Throwable cause)` Constructs an exception that is caused by a network error.

Public methods
`abstract int`	`getErrorCode()` Returns error code, one of `ERROR_*`.
`abstract boolean`	`isImmediatelyRetryable()` Returns `true` if retrying this request right away might succeed, `false` otherwise.
