Project description:
"I have an existing Android APK that I now need to take apart, clean up, and relaunch with a brand-new infrastructure. The job starts by decompiling the current package, then refactoring the Java/Kotlin code and XML layouts so the app feels fresh and fully my own. While you’re in there, I want the entire interface redesigned and the user flow tightened; this is more than a reskin, it’s a usability upgrade.

On the functionality side, I’m focused on performance and security. Every call, thread, and permission should be reviewed so the final build runs lean and complies with the latest Play Store policies. Anything that could trigger a copyright strike (assets, identifiers, or snippets) must be removed or replaced, and the package name needs to change.

The app will shift to a new PHP backend with a MySQL database, plus a Firebase account for ads and analytics. All endpoints, tokens, and ad IDs must be wired up and verified in the code before release.

Deliverables
• Decompiled, refactored Android source with new package name
• Fully redesigned UI and improved navigation flow
• Optimized, security-hardened codebase ready for Play Console checks
• Integrated PHP/MySQL backend and Firebase ads/analytics
• Signed, release-ready AAB/APK plus clean source archive

If you’re comfortable jumping between Smali, Java, Kotlin, XML, PHP, MySQL, and Firebase dashboards—and you know exactly how to pass Google’s review first time—let’s talk timelines and milestones." (client-provided description)
