About
Everyone has tried editing photos and pictures in an editor. Most of them are paid or filled with ads. Why not create one and add every possible feature that comes to mind? In this project, create a simple photo editor that allows you to pick any photo from your device, apply basic filters, and save the result.
Graduate project
This project covers the core topics of the Android Developer with Kotlin course, making it sufficiently challenging to be a proud addition to your portfolio.
At least one graduate project is required to complete the course.
What you'll learn
Once you choose a project, we'll provide you with a study plan that includes all the necessary topics from your course to get it built. Here’s what awaits you:
Design the basic layout and load photos from the gallery to the image view.
Make your image lighter or darker by implementing the brightness filter.
Add the save button and see changes in your gallery.
Add another filter — the contrast one.
Add two more filters — saturation and gamma. They will give you more control over an image.
Use coroutines and make your app more responsive, removing all UI freezes and lags.

In this project, I learned how to apply image filters like brightness, contrast, saturation, and gamma at the pixel level. I also gained experience with Kotlin coroutines, separating heavy computations from UI updates. Debugging the filter logic was challenging, but it helped me improve my problem-s ...

I had learnt some nice concept about image filtering as well as implementing coroutines to perform asynchronouse operations which help avoid UI freeze
