One of the best ways to display huge lists in Android is through RecyclerView. As developers, you all might have used it. We have many advanced features like view holder patterns, rich animation, Diff-Utils callback to improve performance, etc. Apps like WhatsApp and Gmail use RecyclerView to show endless conversations.

One of the significant RecyclerView features that I use is view types. We can display multiple view types in the same RecyclerView. …

In this article, we’re going to learn how to detect if the app is in the foreground or background. Along with that, we’ll also learn how to detect the visible activity to the user.

Use-cases

In the old days, detecting whether the app is in the foreground or not was one of the common tasks that any android developer used to perform. Back then we didn’t have any fancy libraries like LiveData. So developers were responsible to perform actions when the app was in the foreground.

You’re going to learn everything about layouts in Jetpack Compose from the basics to advanced concepts. In the course of this article, you’ll learn about each layout, with real-time examples that you can directly copy-paste into your Compose project to get hands-on experience.

Note: Jetpack Compose recently moved to beta. This means there will no longer be any drastic changes in the API structure. So it would be a great time to learn how to work with this next-generation UI kit for Android development. Layouts are the basic building blocks of the UI, so enjoy the article.
