The key stages of Android development generally include the following:
Ideation and Planning: This is where the initial concept for the app is developed and planned out.
Design: This stage involves creating the app's user interface and user experience.
Development: The actual coding of the app takes place during this stage. It includes both front-end (user interface) and back-end (server and database) development.
Testing: This stage involves checking the app for bugs and usability issues. It may include unit testing, integration testing, and user acceptance testing.
Deployment: Once the app has been tested and any issues have been fixed, it will be deployed to the Google Play Store.
Maintenance: After the app is released, it needs to be maintained and updated regularly to keep it running smoothly and to add new features or improvements.
