Google Play Console Handling
• App Release and Management:
• Upload APKs and App Bundles, ensure correct versioning, and manage signing keys.
• Control alpha, beta, and production release tracks to gradually test new features.
• Use Staged Rollout to gradually release updates to a portion of the users, monitor for issues, and increase the percentage as confidence grows.
• User Feedback & Reviews:
• Actively monitor and respond to user feedback.
• Address issues highlighted in the reviews or bug reports and release updates based on user feedback.
• App Metrics and Performance Monitoring:
• Regularly check the Play Console metrics for crash reports, ANRs (Application Not Responding), and app performance insights.
• Use this data to improve app stability and optimize performance across different devices.

Testing & Release Process
• App Testing:
• Unit Testing using JUnit for individual component testing.
• Integration Testing using frameworks like Espresso for UI testing and end-to-end testing of app components.
• Automated Testing for CI/CD pipelines to ensure code stability across different versions and environments.
• Beta Testing and Testers Management:
• Run beta tests through the Play Console's beta release track to gather feedback before releasing an app to the public.
• Use Firebase Test Lab for automated testing on a wide range of real Android devices.
• App in Developer Mode:
• Keep the app in developer mode to restrict access to only development team members during testing.
• Use debug signing keys and debug builds for internal testing and development.
• Enable developer options on test devices, such as USB debugging, mock locations, and logging.

App In Test Mode
• Setting Up Test Environments:
• Create staging environments to mimic production conditions for testing purposes.
• Set up test servers and use mock APIs for features that arent ready to go live yet.
• Managing Testers:
• Add testers to closed testing tracks via the Play Console to receive test versions of the app.
• Monitor their feedback and app behavior during this phase.
• Testing in Various Stages:
• Use alpha/beta releases in the Play Console to distribute pre-release versions to select groups of testers.
• Incorporate features like internal testing for immediate team and open beta testing for a broader user base.

Releasing The App
• Staged Rollout:
• Use staged rollout to release the app gradually to a smaller percentage of users to ensure stability.
• Monitor feedback and crashes before increasing the rollout percentage.
• Final Release:
• Once testing is successful and no major issues are identified, promote the release to the production track.
• After the final release, ensure continued monitoring using Google Play Console and Firebase Analytics to handle post-release crashes or issues.
