You need a lightweight Android XRP price-alert app that pulls Coinbase market data, monitors user-defined high and low thresholds, and reliably triggers notifications even when the app is in the background. I have 9+ years of software development experience with Java, mobile development, REST APIs, real-time data workflows, and notification-driven systems. I can build the app around Coinbase’s API, keep the current XRP price updated efficiently, let users configure both alert thresholds, and use Android background/notification mechanisms to make alerts reliable without unnecessary battery usage. I’ll also structure the API layer cleanly so provider changes or additional cryptocurrencies can be added later without rewriting the app. Which Coinbase endpoint or API version do you currently plan to use?

⚠️ IF YOU'RE NOT HAPPY YOU DON’T PAY ⚠️ I think we’re a strong fit for this XRP price-alert app. I’d keep it lightweight and native on Android, with a clean live-price screen, user-defined high/low thresholds, and reliable background notifications. I’d use Kotlin with Coinbase market data, a foreground/background-safe update strategy, and Android notifications/alarms so alerts still trigger when the app isn’t open. The first thing I’d verify is how frequently you want prices refreshed, because aggressive polling can hurt battery life and may hit API limits; if Coinbase supports a suitable streaming feed, I’d prefer that for faster updates. Multiple 5-star reviews on Android apps, API integrations, and real-time data projects. I’d love to chat about your project! The worst that can happen is you walk away with a free consultation.

Hi, I can develop the XRP price-alert Android app with real-time Coinbase data, customizable high/low alerts, background monitoring, and reliable push/alarm notifications. I’d use Coinbase’s WebSocket ticker feed for near real-time XRP price updates and implement Android background services/alarms with battery-efficient notification handling. Coinbase specifically recommends WebSockets for real-time market data. Thanks Kuldeep

Hello. I am new to Freelancer, but not to software development: I have been programming web, API, database and application solutions for 20 years. I want to be transparent: I do not yet have public Android work samples on this Freelancer profile. To remove that uncertainty, I can prepare a small web-based proof of concept in less than 24 hours, before the final Android build. It will show the live XRP price from Coinbase, configurable high/low thresholds and the alert logic working. This proof will be provided at no additional cost. I have already verified the public Coinbase XRP-USD endpoint and confirmed that it returns the current price without requiring a Coinbase account or API key. The Android app will include: • current XRP price from the Coinbase public API; • configurable low and high alert prices; • persistent settings after closing or restarting the phone; • sound, vibration and Android notifications when a threshold is crossed; • background monitoring using an Android foreground service, with a WorkManager fallback; • automatic restart after device reboot; • connection/API error handling; • tested APK, complete source code and installation instructions. Repeated alerts will be prevented until the price returns to the normal range and crosses a threshold again. Final delivery will take 2 days. I only need to confirm the display currency (USD or INR) and the desired refresh interval.

Leveraging my expertise in AI and automation, I can bring unique capabilities to your project, such as optimizing workflows in retrieving the latest XRP values or implementing sophisticated notification and alarm system. Let's collaborate to create an app that not only meets but exceeds your expectations, providing users with an accurate and reliable XRP price-update experience.

The core challenge here is not just displaying the XRP price, but making sure the app reliably receives updated market data and triggers alerts at the right price levels, even when the app is running in the background. For an app like this, I’d focus first on the Coinbase data integration, real-time price updates, user-defined high and low alerts, reliable notifications/alarms, and background functionality. I’ve worked on custom mobile applications where the main work involves API integrations, real-time data handling, notification systems, and building clean, responsive interfaces. I also use AI tools to speed up development and debugging while keeping the code structured, reliable, and maintainable. That matters for a price-alert app like this because the data and alert logic need to remain dependable even when the user isn’t actively using the application. * Do you already have a preferred Coinbase API endpoint or should I determine the best option for the XRP price data? * Should users be able to create multiple high/low price alerts, or just one of each? * Do you already have a preferred UI design or reference app you’d like the interface to follow?
