How to compress multiple images ?

[zetbaitsu]

        List<File> imageFiles = new ArrayList<>();
        Flowable.fromIterable(imageFiles)
                .flatMap(new Function<File, Publisher<File>>() {
                    @Override
                    public Publisher<File> apply(@NonNull File file) throws Exception {
                        return new Compressor(MainActivity.this).compressToFileAsFlowable(file);
                    }
                }).subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Consumer<File>() {
                    @Override
                    public void accept(File file) {
                        compressedImage = file;
                    }
                }, new Consumer<Throwable>() {
                    @Override
                    public void accept(Throwable throwable) {
                        throwable.printStackTrace();
                    }
                });
