Handling screen orientation changes is a classic challenge in Android, and the MVVM architecture with Android Jetpack provides an elegant and robust solution. MVVM Core Principle: Separate UI from Data The ViewModel is designed to survive configuration changes (like rotation). The UI (Activity/Fragment) is destroyed and recreated, but the same ViewModel instance is used for…
Upgrading an Android SQLite database without losing data is a fundamental task. By default when we do the upgrade it generally drop the table and recreate the table again. In this the existing user data will be lost and create a major issue with existing user. Here’s a clear, step-by-step guide on how to do…
Use Flows to represent streams of data that are asynchronous and can change over time. They are the cornerstone of a reactive and lifecycle-aware app. 1. Choosing the Right Type of Flow Flow Type Purpose Best For Flow<T> Cold stream that emits data when collected. Doesn’t hold state. Data layer: Streaming results from Room DB,…
We need Jetpack Security in Android mainly because it helps developers easily and securely store sensitive data without having to implement complicated cryptography themselves. What is Jetpack Security? Jetpack Security (androidx.security) is an Android Jetpack library that provides robust and easy-to-use security best practices for storing data on a user’s device. It’s designed to simplify the process of…
The “best” approach has evolved significantly. The modern, recommended approach by Google is to use the SplashScreen API (Core SplashScreen library) introduced in Android 12 (API 31) and backported to all Android versions through AndroidX. This approach ensures a consistent, performant, and flicker-free splash screen experience across the vast majority of devices. Recommended Approach: SplashScreen…
Implementing an instant search (also called “search-as-you-type”) from a server using Kotlin Coroutines is a classic use case for coroutines and flows. The key is to debounce user input to avoid flooding the server and cancel previous requests to avoid out-of-order results. Here’s a step-by-step guide with best practices. We’ll use a reactive approach with…
The Flow API is the part of Kotlin Coroutines, offers several advantages. Unlike LiveData, Flow manages multiple values as streams. It doesn’t require a LifecycleOwner and is always active, meaning values can be collected as long as the flow is active. Additionally, Flow enables using Kotlin Coroutines features like exception handling, flow control, and operator…
Hi everyone, In this article, we are going to learn how to hide the production API key or any sensitive data to share with the app. In every application, we used many sensitive data like API key or app id or secret key to use in our app. As we know this information/data is very…
Hello everyone, Today in this article, we are going to learn about localisation to support the multiple languages in our android apps. Localisation is the basic need for the app as we want to engage the app for the different regions to make them understand their language. Generally, we handle the localisation in two different…
Hello everyone, In this article, we are going to learn something to handle the callback by using Kotlin Coroutines. As we are already familiar with Coroutines in my earlier post here get started Coroutines. Alright, then let’s started to learn about the deal with callback in coroutines. In android, we mostly use the UseCase to…
