As an Android developer, your responsibilities and duties vary, depending on your position and the size of your team. You may be involved in the planning stage, aggregating requirements for the app, and planning how it will be developed. You may be part of the coding team that writes the program. Some developers work on the testing phase before the app is launched, and others work on patches to fix bugs as they are discovered. Coding updates and seeing them through to release is often a long-term and ongoing aspect of Android development. If you work independently or for a small firm, you may be involved in all phases of the development life cycle, whereas those employed by larger firms likely have specialized roles.
