Hello There! I’m Md Toriqul Islam, an experienced Flutter developer and mobile app specialist, and I can dive into your project immediately. I am skilled in Flutter framework upgrades, Android SDK/Target API updates, handling breaking dependencies, and managing Google Play Store releases. I understand you need to update the target API level for your two live Flutter Android apps to comply with Google Play's latest requirements, recompile them smoothly, and publish the updated releases. I have extensive experience maintaining Flutter codebases, updating outdated plugins, and navigating Google Play Console submission processes. To ensure a seamless update and publishing process, I have a few quick questions: 1) Which Flutter version were the apps originally built on, and do you have access to the source code repository? 2) Do you have active Google Play Console access and the app signing keys (keystore files) ready for building the new release binaries? 3) Are there third-party plugins in the apps that might require major version updates to support the target Android API? I’m ready to start immediately, update both applications, and push the new versions to production. Feel free to share additional details or ask questions. Looking forward to hearing from you. Best regards, Md Toriqul Islam

Que tal amigo, buen dia, he visto el error que presentas y se lo que se debe hacer, solo que al elevar la versión de android se tienen que hacer las pruebas de tu app para ver que no se rompa nada (que algo deje de funcionar) si tu app tiene pruebas unitarias (unit test) con subir la version es más que suficiente ye ejecutar las pruebas, en caso de que no las tenga, yo te puedo ayudar a generar el nuevo compilado pero no puedo asegurarte que la app siga funcionando al 100 después de realizar este upgrade. Espero tu mensaje, saludos!

Hello, Tu problema no es solo compilar dos apps: es evitar que Google las bloquee por una API desactualizada y dejar todo publicado sin sobresaltos. Puedo ayudarte a revisar la integración actual en Flutter, actualizar la API a una versión compatible, compilar ambas apps y dejar listas las nuevas versiones para publicación. He trabajado con Flutter, APIs, publicación de apps y ajustes técnicos en proyectos Android, así que puedo detectar rápido dónde está el cambio necesario y resolverlo con claridad. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. Lo ideal sería revisar primero qué API menciona Google, si el cambio afecta auth, permisos o dependencias, y confirmar el estado de firmas y versionado antes de publicar. Si me compartes el email de Google y los datos de publicación, puedo decirte el plan exacto hoy mismo. ¿Qué API específica pide actualizar Google y ya cuentas con acceso a Google Play Console y a las claves de firma de ambas apps? Looking forward to your reply so we can finalize the exact plan. Gracias, Asad

Hi, Tengo las dos apps Flutter en producción y el aviso de Google suele ser por target API level (compileSdk / targetSdk). Actualizo ambos proyectos a la versión exigida, reviso dependencias, compilo release, pruebo en dispositivo y subo la actualización a Play Console. He publicado apps Android en producción (Flutter y nativo) y conozco el flujo de subida, firmas y revisión de Google. €15 — puedo empezar en cuanto me pases acceso al repo y a Play Console. Saludos

Hi, I understand you have two Flutter Android apps in production flagged by Google Play for the target API level requirement both need to be updated to target Android 15 (API level 35) or higher before the August 31, 2026 deadline to stay available to new users on newer devices. I will review both Flutter codebases, check their SDK and Android configuration, and update the target and compile SDK versions to API 35. I will update Gradle, AGP, Kotlin, and any incompatible dependencies as needed, address relevant Android 15 behavior changes, and test both apps on older and newer Android versions. Once everything is stable, I will generate signed AAB files, submit both updates through the Play Console, and confirm that the target API warning is cleared. The final timeline and cost will be confirmed after reviewing both codebases, dependencies, and the complete scope. I'll need access to both repos and Play Console to get started.

Hi, I'm Denis. I understand you need to update the back-end API for your two Flutter Android apps and republish them after compiling. The main task is straightforward: update the API to the required version, ensure the apps remain functional, then compile and publish them through the Play Store. I’ll review the current API version, check for breaking changes in the new version, and adjust the app logic accordingly. Testing will focus on data flow between the updated API and the apps to confirm everything works as expected. I’ve handled similar updates where apps needed to stay compatible with a newer API while preserving existing features. The process involves checking for deprecated endpoints, updating SDK dependencies, and validating responses to avoid runtime issues. I can start working right away. Let’s connect and discuss the details. Thanks, Denis.

Hola, soy Rafael. Puedo encargarme de actualizar las dos aplicaciones Flutter para cumplir con el nuevo requisito de Google Play, recompilarlas y publicar las nuevas versiones. Primero revisaría el correo de Google para confirmar exactamente qué API/Target SDK exige la actualización y comprobaría la versión actual de Flutter, Gradle, Android Gradle Plugin y dependencias de cada app. A partir de ahí haría los cambios necesarios sin tocar funcionalidades que ya están estables. Después compilaría ambas aplicaciones, corregiría posibles incompatibilidades derivadas del cambio de API, generaría los AAB firmados y haría una validación básica en Android antes de subirlos a Google Play Console. También revisaría que versión, `targetSdkVersion`, `compileSdkVersion`, permisos y librerías queden alineados con los requisitos actuales de publicación. Puedo ocuparme de todo el proceso hasta dejar las 2 actualizaciones publicadas o listas para revisión en Google Play. Contáctame para hablar en detalle del proyecto y enviarme el correo de Google junto con acceso al código fuente y Play Console.

Hello, A Flutter app I updated from an old API to a newer version handled 30% more concurrent users without crashes. That’s the kind of stability we need here. Updating an outdated API without breaking the live apps isn’t trivial, but it’s manageable if we treat the existing code as a reference. I’d use the latest Flutter-compatible API version and keep the existing endpoints intact to avoid rewriting the mobile side. The biggest improvement will be removing deprecated calls and ensuring the API handles the current load without throttling. Customers won’t notice the update, but the apps won’t break during submission or afterward. Every change will be tested locally before the final build, and the apps will be published under the same package names to keep users’ updates seamless. Let me know if you’d like to go over the API docs first. Thanks, Lazar

Dear Client, I’m an experienced Flutter/Android developer with 10+ years of mobile development experience, including maintaining and publishing production applications. I understand you need both existing Flutter Android apps updated to a newer Android API/target SDK to satisfy Google’s requirements, while preserving current functionality. I can review the Flutter/Gradle dependencies, update the required SDK and plugins, resolve compatibility issues, generate signed release builds, test both applications, and publish the updates through Google Play Console. My skills include Flutter, Dart, Android SDK, Gradle, Java/Kotlin, Play Console, app signing, debugging, and production releases. Questions: 1. What target API level does Google’s email require? 2. Do you have the existing keystores and Play Console access? 3. Can you provide both Flutter source repositories? Best regards, Md Ruhul

Review both Flutter projects, current Flutter/Dart versions, Android Gradle configuration, dependencies, and Google’s API requirement. Upgrade the required Android API/SDK and Gradle configuration carefully, keeping existing app functionality intact. Update outdated Flutter packages/plugins and fix any breaking changes caused by the API upgrade. Resolve Android build, manifest, permission, dependency, or compile errors and verify release builds. Test both apps on suitable Android versions, checking login, API communication, notifications, navigation, and critical existing features. Configure signing/versioning and generate production-ready AAB files for both applications. Prepare the required Google Play release updates and publish the new versions, addressing any Play Console warnings or API compliance issues. If the API change causes unexpected behavior, I will trace the affected integration, implement the compatible solution, and retest before publishing.

Ciertamente, aquí el punto no es “actualizar una API” sin más: Google te está pidiendo una actualización de las dos aplicaciones Flutter que ya están en producción, y lo importante es hacerlo sin romper lo que actualmente funciona. Puedo revisar la configuración de ambas apps, actualizar la versión de API/SDK que exige Google, comprobar que sigan compilando correctamente y preparar las nuevas versiones para su publicación. También conviene verificar cualquier cambio de compatibilidad antes de subirlas, porque una actualización aparentemente pequeña puede provocar errores al compilar o en producción. He trabajado con aplicaciones móviles y APIs, así que prefiero revisar primero exactamente qué versión está solicitando Google y qué tienen actualmente las dos apps, en lugar de asumir. Si me compartes el email de Google o el requisito concreto que te indicaron, puedo decirte rápidamente qué hay que cambiar en ambas aplicaciones.
