Overrides [Synchronizer.onSubmissionErrorHandler](../-synchronizer/on-submission-error-handler.md)
|
||
|
|
|
||
|
|
A callback to invoke whenever a server error is encountered while submitting a transaction to lightwalletd.
|
||
|
|
Returning true signals that the error was handled and a retry attempt should be made, if possible. This callback
|
||
|
|
is not called on the main thread so any UI work would need to switch context to the main thread.
