Rxjava load, save and display images in one pipeline?

Question

Android

Bottom line: you need to load the image, save it and display it. Everything works, but I don't like the current code:

Single.fromCallable { call.execute() }
            .map { it.body?.byteStream() }
            .map { BitmapFactory.decodeStream(it) }
            .map {//это мне не нравится
                it.compress(Bitmap.CompressFormat.JPEG, 90, getOutPutStream())
                it
            }
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribeBy({ it.printStackTrace() }, {
                imageView.setImageBitmap(it)

            })

I have poor knowledge of Rx, but it seems to me that this approach is not correct. The question is how to write it beautifully. Not to take out the received bitmap as a separate variable and then create a new pipeline with it? How to perform several unrelated operations in one pipeline?

Answer 1

This approach is wrong. Use Glide to upload images.
