Get Bitmap From Url With Other Api Calls Parallelly Using Glide And Rxjava In Android

I am making two API calls parallel in the following way. Single.zip(API1.subscribeOn(Schedulers.io()), API2.subscribeOn(Schedulers.io()), Bifunction())).subscribe()

Solution 1:

While loading the image from Glide, we should either call the .submit() method or .into(...) in order to successfully get the bitmap or load the image.
