Google Slides is the official Google presentation app that lets you work with this type of file directly on your Android device. You can thus both open files created on your computer and also create new ones.

With Google Slides, not only will you be able to work with this type of file, but you'll also be able to share them easily with other users in your work group. Just like with all other Google tools, several users can work on the same file simultaneously. You can even work without an Internet connection and then apply the changes as soon as you go back online.
