Senior Android developers have additional tasks in addition to coding, such as making decisions and designing robust and scalable applications.

An Android Developer simply comprehends the project requirements defined by the company and then converts them into a concrete application. The app can be published and uploaded to Google Play Store. Any Android app usually goes through the following three stages:

In addition to full-stack developers, organizations also recruit programmers (responsible for coding) and developers (responsible for designing the app) for their application development team.
