If you are developing a stock-trading app, live sports score keeping app, or even a food delivery app with a real-time tracking screen, you need a method to show data updates in real-time. LiveData works great for basic use cases, but it might not be able to handle continuous streams of fast-changing values.<\/p>\n\n\n\n
Challenge:<\/strong><\/p>\n\n\n\n How do you show continuously updating data (e.g., stock prices) without LiveData?<\/p>\n\n\n\n Solution:<\/strong><\/p>\n\n\n\n Make use of MutableStateFlow in ViewModel and collect it in the UI with lifecycle-awareness.<\/p>\n\n\n\n StateFlow is a clean, efficient way to manage real-time UI updates in modern Android apps. It\u2019s lightweight, lifecycle-aware, and much easier to reason about than juggling LiveData and manual observers. If your app depends on live data, you should hire Android engineers<\/a> who are comfortable with Kotlin Flow.<\/p>\n","protected":false},"excerpt":{"rendered":" If you are developing a stock-trading app, live sports score keeping app, or even a food delivery app with a real-time tracking screen, you need a method to show data updates in real-time.
