Upload file from android client

What is the best solution to upload a file with request DTO using the ServiceStack Android Client?

If this is the Xamarin .NET Android ServiceStack Client then you would use PostFile or PostFileWithRequest API’s.

If this is the ServiceStack.Java JsonServiceClient it doesn’t include support for uploading files, you can just use any HTTP Client that supports multipart/form-data Content-Type. Here’s an example using the Apache Java HttpClient.
