Hey everyone,
I’m working on an Android app and using Retrofit for network calls. I’ve noticed something weird. Even though I’m using threads and AsyncTasks, Retrofit seems to be processing my requests one at a time instead of in parallel.
I’m trying to figure out how to make Retrofit handle multiple requests at once. Ideally, I’d like to have 3 or 4 requests running simultaneously. Is there a way to do this without changing my backend?
I’ve looked through the docs but couldn’t find anything helpful. Has anyone run into this before or know a good way to handle it?
Thanks for any help you can give!
hey there! have you tried using coroutines? they’re super handy for concurrent operations. you could launch multiple coroutines for different api calls. also, whats your OkHttpClient setup like? tweaking the connection pool might help. curious to hear more about your specific use case - what kind of requests are you making?
yo, ran into this b4. check ur retrofit builder, make sure u set .callFactory(OkHttpClient()) with right configs. i bumped maxRequests and maxRequestsPerHost in dispatcher. worked like charm 4 me. gl!
RxJava offers a solid alternative to achieving concurrent network operations with Retrofit. In my experience, modifying your API methods to return observables not only streamlines asynchronous programming but also allows for combining results efficiently using operators like flatMap and zip. By scheduling these operations on background threads, you can avoid blocking the main thread and improve error handling. This method provided me with better control over cancellation and overall cleaner code compared to traditional AsyncTask implementations, making it a practical solution for parallel API requests.
