Jetpack Compose (sometimes mistakenly called Android Compose) is a powerful new UI toolkit for Android that embodies the principle of ‘Code As UI’, offering aa simpler and faster way to build native android UI using a declarative approach. Of all the UI components in Jetpack Compose, buttons have a special place, as these are the cornerstone of our user interface. They allow the user to take actions, submit forms, and navigate around the app smoothly.

When building apps, it’s tempting to dive right into writing code. But if we do this, there’s a good chance that our code will eventually break, as new changes are made and new features are introduced. This is particularly true of React, a library that’s constantly evolving. Testing in React isn’t only about catching hidden bugs but also about maintaining code quality day-to-day.

Pickers enable Android developers to minimize error-free input and optimize everyday features of their apps, such as date selection, delivering crucial gains in user experience. Users can validate input data by pressing a single button, and ensure structured input without any typing errors (in fact users don’t need to type an input at all). And we can customize the picker to our specific needs, creating better UI for our users.

Jetpack Compose is Android’s modern UI toolkit to build native user interfaces with less code in a fast, consistent way, increasing code maintainability and establishing a tight integration with other Jetpack libraries. Jetpack Compose moves away from the traditional XML-based UI design. It enables you to define your user interface using a closer-to-natural declarative programming paradigm, where developers can describe how they want their user interface elements to look and behave in Kotlin code.

You may have read about hackers using ChatGPT to impersonate your grandma. If that story made you dig a little deeper, you may have learned about the hyper-realistic phishing scams being concocted with generative AI. And if you’ve really gone into the cyber-security weeds, you may have discovered the new breed of infostealer malware stealing passwords and browser log-ins. All sounds very concerning right? Well, it needn’t do.

Since Adobe introduced the PDF in 1993, this versatile file format has played a key role in the digital revolution. PDFs give us a universal languages across different devices, they support interactive and multimedia elements, and they provide robust encryption. Today, Adobe estimates there are over 2.5 trillion PDFs in existence around the world. It’s fairly self-evident, then, that PDF functionalities are now a crucial part of web application development.

The when in Kotlin defines a conditional expression with more than one branch, that’s the statement you need to use when you want to write a Kotlin switch. In Java, we are using switch case statements. In Java, we need to define a break in each switch case, but in Kotlin we don’t need to. There are two ways you can use them in Kotlin. Either as a statement or as an expression.

Efficient handling of asynchronous data streams is an important tool of modern application development. Kotlin Flows, part of the Kotlin Coroutines library, provide a flexible and elegant solution for working with such data streams. Kotlin Flows are part of Kotlin Coroutines – unlike traditional callbacks or RxJava handling, which can be clunkier and may not directly integrate with your existing code structure easily.

In the fast-changing landscape of mobile app development, delivering bug-free apps with a great user experience is essential. But crashes are inevitable, no matter how much developers try to avoid them. There are several mobile crash reporting tools that make the task of identifying, diagnosing and fixing these issues easy as pie.

In programming, exception handling is an essential concept to help developers catch and manage errors in a way that will support the application’s architecture robustness. An Exception is an event which disrupts the normal flow of your Android application. It can occur if a user provides an invalid input, or there are runtime errors, such as division by zero. Exceptions happen when there are unexpected conditions, like IOError file reading failed etc.
