set Uri Resolver Async
Sets a custom async Uri resolver. This method can be called more than once. Subsequent calls will overwrite previous calls. To remove a previously set resolver, pass the value null.
The resolver is invoked on the Engine thread. Avoid blocking; for I/O, switch contexts (e.g. withContext(Dispatchers.IO)).
Parameters
resolver
async resolution function that accepts both relative and absolute uri and returns an absolute uri.
