Waiting for API Calls to complete with RxJava and Retrofit

Question

I'm using RxAndroid and RxJava with Kotlin to make various requests to APIs and reciving them asyncronylusly:

    getClient().sendSomeData(data)
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(
                    {
                        Log.i("upload", "data ok")
                    },
                    {
                        t ->
                        Log.e("upload", "data error: " + t.stackTrace)
                    }
            );


    getClient().sendSomeOtherData(otherData)
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(
                    {
                        Log.i("upload", "otherData ok")
                    },
                    {
                        t ->
                        Log.e("upload", "data error: " + t.stackTrace)
                    }
            );

And so on. What i want to do now is, sort of "wait" for all the api requests to finish and show the progress. How can i wait for all observables to be completed and get a callback with progress?

Answer 1

Answering your first question here and here you will see mentioned the Observable.onCompleted method, which is called after succesful response. Also here is the doc for the this method. So you could simply implement the third Action in subscribe method call and modify your request's state info.

If it comes to the request progress status, I'm not sure, but I suppose that RxJava does not offer this functionality out of the box. However I found the answer here (with use of Retrofit library).
