Explaining the concept of clean architecture:

The idea behind the clean architecture concept is to make the project scalable, easy to maintain and testable, creating separate layers and always depending on abstractions and not concrete classes.

Key points

  1. Independence of frameworks: Your project can never be dependent on an external framework, there must always be a layer that abstracts logic, thus making it possible to remove…

Hello, My name is Rodrigo and i'm a mobile developer, today i i'll teach you how to get images from android camera, there are two ways to get one picture from the native camera app from your device, get an thumbnail, small picture with low resolution just to show to user in tiny image view, and the full image resolution.
