Retrofit With Rx Runs Outofmemory While Trying To Send A Large Base64

Maybe, you should use Flowable with proper backpressure strategy instead of Single. But if you think it's for your adapter you can use Jackson because it's faster than Gson(According to this article). And if you want more performance maybe you should use Protobuf instead of JSON.
