Mitarbeit bei der Entwicklung einer android / iOS App mit Xamarin.

Hi bastianspirek, wir - ein Team aus Web&Mobile Freelancern - haben aktuell wieder einige Mobile-Projekte vorliegen, die wir nicht abdecken können und würden daher gerne unser Team erweitern. Was hast du denn bisher im Mobile-Bereich gemacht? Da stehen alle drei Plattformen, also nehme ich an, Xamarin oder Ionic? Oder auch nativ? Ich würde mich über eine Rückmeldung freuen und gerne über deine Referenzen und unsere Projekte sprechen. Viele Grüße!

Ich will eine Trainingsapp erstellen welche die gleichen Funktionen wie Freelethics hat. Das Backend sollte immer das gleiche sein und in C#geschrieben werden. Kommuniziert wird über einen Webservice und der Datenbank Zugriff sollte mit dem Entity Framework realisiert werden. Um IPhones, Windowsphones und Android abzudecken will ich Xamarin einsetzten und dort mit dem MVVM Pattern arbeiten. Die Website sollte zusätzlich ein CMS beinhalten. Von den Funktionen her sollte die App gleich sein wie Freelethics. Wir wollen einfach anstatt Sportübungen, Übungen zum Überleben in der Freien Natur anbieten. Die Übungen sollen von einem Administrator erfasst werden können. Die Application sollte in mehreren Sprachen zur Verfügung gestellt werden. Um die C...

...GPS/VLT/AIS-140 devices, fire-extinguisher checks, driver licence and badge renewals—and stores the next due date alongside a digital copy. • When a date is approaching, the owner and any assigned RTO Agent receive an in-app alert plus an SMS and WhatsApp message. Admin sees the same warnings in a consolidated panel. I’m happy with mainstream cross-platform stacks such as Flutter, React Native, or Xamarin so long as performance is smooth and the Windows build installs without side-loading. A lightweight web API with a secure SQL or NoSQL backend is fine; just make sure it scales. Deliverables 1. Source code with clear build instructions for all three platforms. 2. Simple cloud or on-premise deployment guide for the backend. 3. Tested notification workfl...

...iPad. The goal is a seamless, touch-friendly version that preserves every existing workflow while taking advantage of iPadOS capabilities. Your task • Review the present SQL Server schema, stored procedures, and any helper scripts. • Design and build an iPad solution that connects securely to the same data set, whether through a native Swift/Objective-C app, a .NET-based wrapper (e.g., Xamarin or .NET MAUI), or a well-optimized web front end—whichever you can justify as the most stable and maintainable. • Implement offline caching for spotty connections and ensure real-time sync when the device comes back online. • Handle authentication/authorization identically to the desktop version so user roles carry over without rewriting our security mod...

I have a collection of Java / Kotlin classes that sit at the heart of my Android app. They manage in-memory data structures, expose that data to the rest of the app, and synchronise it with our back-end through a handful of REST-style APIs. I now need the exact same behaviour expressed in clean, idiomatic C# so the project can be compiled under the .NET Android toolchain (Xamarin or MAUI—whichever you prefer). Your task is to translate every class, interface, and public method signature to their .NET equivalents, preserving naming, access levels, and logic while embracing C# conventions such as properties, async/await, and nullability annotations. The resulting code must build and run in Visual Studio, target current Android SDK levels, and integrate with the existing API end...

Our mobile app is in production; I now need a focused set of improvements completed: • Local data must be stored seamlessly when the connection drops, then pushed to the server automatically the moment the device reconnects. No manual triggers—users should never notice they were offline. • A compact dashboard page showing overall student performance (simple charts or progress indicators are fine) has to be added to the teacher section. Data sources and existing view-models are already in place. • Teachers also need a dedicated Attendance report. A clean list or table view filtered by class/date will do; exporting or printing is not required at this stage. • Replace the current username/password screen with Google Authenticator sign-in. If you prefer Firebase,...

I need my existing Xamarin Forms mobile application fully migrated to .NET MAUI so it builds and runs flawlessly on both iOS and Android. The current codebase follows MVVM, uses Xamarin Essentials and local SQLite storage, and includes a few custom renderers; all of that functionality must remain intact in the new MAUI version. While you are inside the codebase, I also want to introduce two new capabilities: – Push notifications (FCM for Android, APNs for iOS) connected to the REST back-end that already emits notification payloads. – Email/password user authentication with secure token refresh, calling my existing API endpoints. Deliverables • A clean .NET MAUI solution that compiles in Visual Studio 2022 (or later) with signed Release builds for both i...

...Windows. The new app must behave identically to the existing one, so two core capabilities have to make the jump with zero regressions: • Push notifications – keep the same Firebase/APNs flows, badges, and deep-link handling. • Full Bluetooth support – both classic SSP (for legacy serial-port exchanges) and BLE (for modern GATT reads/writes and device scanning). I will hand over the entire Xamarin repo, current notification keys, and the Bluetooth service specs. I expect the MAUI project to build and run from Visual Studio 2022, produce signed packages for Android (AAB), iOS (IPA/TestFlight), and a Windows MSIX, and to follow best practices for dependency injection, platform-specific handlers, and Blazor component structuring. Deliverables 1. Source cod...

i am newly learn for Xamarin (mobile app for android and ios) and i need someone who can educate me and help to resolve several defects.

I have a mature Xamarin Forms business application that runs on both iOS and Android. I now want the whole code-base upgraded to .NET MAUI so I can maintain a single project that stays current with Apple and Google store requirements. The solution uses several third-party libraries beyond the standard Xamarin stack, so part of the job is to assess each package, replace or update it where needed, and make sure the functionality remains unchanged after the move. I will provide the current source, NuGet list, and a short document that explains what every library does inside the app. What I need from you is a clean, compilable .NET MAUI project that builds and runs on the latest stable Xcode / Android SDK versions, with all existing screens, business logic, and navigation worki...
