Modernize Fertility Charting App

@AwaisChaudhry

Hi there, I'm confident I can get your Fertility Charting App compiling on the latest Android Studio, targeting Android 10+ while preserving every screen, workflow and data model. I have modernized Java Android apps: upgrading compile/target SDK, migrating from legacy support libraries to AndroidX, updating Gradle plugins and dependencies, and ensuring 64-bit compliance and Play Console readiness. I will identify deprecated APIs, replace with AndroidX equivalents, maintain UI/UX exactly as today, and apply careful performance tweaks only if they don’t change behavior. Deliverables: updated project source in a ZIP, release-ready APK and AAB that load on Android 10–16 devices and emulators, and a concise change log describing every file or library touched plus reproducible build steps. Approach: 1) raise compile/target SDK; 2) migrate deprecated calls to AndroidX; 3) update Gradle, dependencies and signing; 4) ensure 64-bit compliance and policy readiness; 5) verify all screens, flows and data models remain unchanged; 6) test on emulators and real devices; 7) package ZIP, APK, AAB with instructions. I can start immediately and plan to deliver a review-ready package within 12–14 days. Are there any specific third-party services or native libraries you must keep compatible, or any CI/CD constraints I should align with? Best regards,

Hello, HAVE HANDS-ON EXPERIENCE WITH SUCH PROJECT I have 9+ years of proven experience updating legacy Android apps to modern SDKs and I fully understand your requirement to modernize your fertility charting app without changing behavior. The goal is to upgrade the app to the latest Android Studio and SDK levels so it installs cleanly on Android 10–16 while keeping every screen and feature identical. -->> Upgrade compile/target SDK, migrate to AndroidX, and replace deprecated APIs -->> Update Gradle, dependencies, signing config, and 64-bit compliance -->> Preserve existing UI/UX, data model, and workflows with zero functional changes My approach: careful migration with full regression testing, clean build scripts, and a detailed changelog so you can reproduce the build. I would approach your project by starting with wireframes and getting the UI/UX design completed, before starting the actual development phase. I can successfully implement this project from start-to-finish. Let's get your app Play Store ready again while keeping everything you love unchanged. Thanks & regards Julian

Hi, thanks for your job posting. I have read your description carefully and I am sure that I can update your fertility charting app so it builds cleanly on the latest Android Studio and installs without issues on Android 10 through Android 16, while keeping all existing behavior exactly the same. I have strong experience modernizing legacy Android apps by raising compile and target SDK levels, migrating to AndroidX, and replacing deprecated APIs without altering UI or workflows. I’ll update Gradle, dependencies, and signing configs to ensure 64-bit compliance and full Play Store policy readiness. The app’s current screens, data model, and charting logic will be preserved precisely, with only safe performance or compatibility improvements where appropriate. I’m comfortable working primarily in Java and XML and will introduce Kotlin only if it cleanly replaces deprecated components. You’ll receive the updated project source as a ZIP, along with a release-ready APK and AAB tested on emulators and physical devices. I’ll also provide a concise changelog detailing every modified file or library and clear build instructions. The final build will pass the Play Console pre-launch report and function identically to the current version on older devices. Best regards. Jijo

Hi there, ★★★ Mobile App Development / Android App Development Expert ★★★ 10+ Years of Experience ★★★ To modernize the fertility charting app effectively, I will follow a structured approach: 1. Analyze the current codebase and identify deprecated APIs along with the outdated SDK requirements (8 hours) 2. Update the compile/target SDK level and migrate to AndroidX, ensuring all dependencies are up to date (10 hours) 3. Test the application on Android 10 to 16 devices and emulators, making sure all functionalities remain intact (5 hours) 4. Prepare the updated project source, release-ready APK, and change log (4 hours) What I need from you: 1. Access to the current codebase and any documentation available 2. Information on specific devices/models to test the application on 3. Approval for any performance optimizations that may impact existing functionality I look forward to connecting at your convenience to ensure the project's success. Best Regards, TechPlus Team

Hi there To modernize your app without altering a single screen or workflow, the most critical part is isolating build and API upgrades from runtime behavior. I’ll approach this by raising compile/target SDKs, migrating support libraries to AndroidX, updating Gradle and dependencies for 64-bit and Play policy compliance, and replacing deprecated calls only where required. UI, data models, and flows will remain untouched. Any performance tweaks will be conservative and verifiable. For context, I’ve handled legacy Android upgrades where the success metric was strict parity—same screens, same data, same results—while passing modern install and Play Console checks. My process is simple: upgrade tooling and SDKs, migrate deprecated APIs surgically, validate on Android 10–16 devices/emulators, and produce a clean release APK/AAB with a precise changelog. I’m ready to start with a quick repo audit and then provide an exact timeline and fixed price once dependencies are confirmed.

Hi there, Your fertility charting app supports older devices but does not install on Android 10+ due to an outdated SDK. It requires an update to support current devices while supporting everything exactly as it is. I have been working on updating and maintaining Android apps for about 9 years. Here is my plan: - Update compile/target SDK to the latest stable version. - Convert deprecated APIs and support libraries to AndroidX. - Update Gradle, dependencies, and signing configurations for 64-bit and Play Store requirements. - Support everything exactly as it is—no changes to functionality or UI. - Optimize performance where it doesn’t change functionality. Timeline: about 2-3 weeks for a full update, tested on Android 10-16. Deliverables: - Updated project source in a ZIP. - Release-ready APK and AAB that install on Android 10+. - Change log listing every file and library updated. - Build instructions that you can reproduce. The app will install from Play Console pre-launch report with zero critical issues, and charts, data registration, and syncing will work exactly as they do now. I have experience with similar SDK updates, where everything works as is while supporting modern Android requirements. Talk soon, Kamran.

⭐⭐⭐⭐⭐ ✅Hi there, hope you are doing well! I have extensive experience updating legacy Android apps by upgrading SDK versions and migrating from support libraries to AndroidX, ensuring smooth installation and flawless operation on modern Android versions. The most critical part of this project is careful migration of deprecated APIs and update of build configurations to comply with current Play Store standards without altering the existing app behavior. Approach: ⭕ Upgrade compile and target SDK to the latest stable versions in Android Studio. ⭕ Migrate all deprecated support library usages to AndroidX. ⭕ Update Gradle files, dependencies, and signing configs for 64-bit compliance. ⭕ Test APK and AAB on Android 10 through 16 emulators and physical devices to ensure zero warnings and functional parity. ⭕ Provide a detailed changelog and build instructions. ❓ ❓ Are there specific third-party libraries currently being used that I should be aware of for compatibility checks? ❓ Would you prefer all changes to remain in Java, or is incremental Kotlin conversion acceptable where it improves stability? I am confident I can modernize your fertility charting app swiftly while preserving every feature and screen exactly as they are today. I look forward to delivering a launch-ready build you can rely on. Best regards, Nam
