Learning RxJava (for Android) by example
Why Stack Overflow recommends it
Stack Overflow users link it when answering Android questions that can be solved with reactive programming, such as combining Spinner selections, handling socket or network callbacks, and surviving configuration changes.

What it is
A 74-minute InfoQ talk from a San Francisco Android meetup in which Kaushik Gopal introduces RxJava and RxAndroid for beginners. He walks through primers on both libraries and then implements real-world Android use cases with them.

[this video] this video does a good job of explaining the way you can use these libraries in for this purpose. you should use both to make it easier

If I understand it clearly, you need some sort of callback which only fires when selection has been made in all 3 Spinners. If this is the case, it might be possible through RxJava. You can watch this video [this video] as a tutorial. If you're familiar with RxJava then just check out the `combineLatest` thing in this tutorial [LINK] , I recall that the video talked about it. If you come up with a way what you want, post it as answer (and mark it) + update your question as well. It will be helpful for others.

Have you tried RxJava? It's quite tricky library for reactive functional programming but I have used it for some time and it's rewarding. Have a look at that: [this video]

I think you will benefit from learning to use RxJava [LINK] / RxAndroid [LINK] . I believe that this presentation [LINK] (and a video link [LINK] ) will help you with a solution, he was presenting a solution to a similar problem. If you never used RxJava before perhaps you should start with his first presentation [LINK] and video [this video] . Good Luck!

I'd like to first start by noting a few things I see in your code. You are using HttpClient with NameValuePairs for your post, which would have been fine in a little while ago, but are now deprecated. I'd advise you to look in to Okhttp and Retrofit, as they will make your life A LOT easier in terms of network calls and separate your code in to layers so that unit testing is easier. You can find Okhttp here: [LINK] In your doInBackground function, you are making the network call, but then are returning null. Try changing the return type of the AsyncTask to something like a custom object that holds reference to what you expect your response to look like, or if you follow the Observable patter
