Launch is a milestone, not an endpoint
Android releases, Google Play policies, dependencies and business processes continue to evolve. Maintenance planning should identify the owner of each update and the budget for routine review.
Measure before changing
Crash reports, performance metrics, support tickets and user journeys help prioritize fixes. Separate urgent security and reliability work from feature requests.
Modernize in safe increments
Review architecture, outdated libraries, authentication, API contracts and testing coverage. Avoid unnecessary full rewrites without comparing migration risks.
Protect business continuity
Maintain signing keys, source code access, environment documentation and a rollback plan. Ownership arrangements should be explicit at the beginning of the engagement.
