Building a server-synced event app for Android

I’m working on an Android app that shows upcoming events. The front-end part is done, but I’m stuck on the backend. The app needs to sync with a server all the time. I’ve looked online for help, but there’s so much info that I’m lost. What should I focus on to create the backend for this app? I’m not sure where to start or what technologies to use. Any advice on how to handle constant server communication and keep the event data up-to-date would be great. I’m especially interested in learning about efficient ways to sync data and handle real-time updates. Has anyone built something similar before? What were the challenges and how did you overcome them?

For your server-synced event app, I’d recommend exploring WebSockets for real-time communication. They provide a persistent connection, allowing instant updates without constant polling. Combine this with a robust backend framework like Node.js or Django, and a database like PostgreSQL for data storage.

To handle efficient syncing, implement a timestamp-based system. Each event can have a ‘last_updated’ field, allowing your app to fetch only the changes since the last sync. This approach significantly reduces data transfer and improves performance.

For scaling, consider implementing a caching layer with Redis to reduce database load. Also, look into implementing pagination for your event lists to manage large datasets effectively.

Lastly, don’t forget to implement proper error handling and retry mechanisms to ensure smooth operation even with intermittent connectivity issues.

yo, have u checked out socket.io? its pretty sweet for real-time stuff. pair it with express.js and mongodb, and youve got a solid backend setup.

for syncing, maybe use a timestamp system? only grab new/updated events.

watch out for battery drain tho, constant syncing can be rough on phones.

hey im thinkin firebase might be a good starting point. its real-time syncing is handy. i wonder wut types of events and user load u expect? keen to know how u might handle scaling and updates.
