Mastering Animation Loops in Kotlin for Your Android Project

Creating an engaging and interactive application can be a challenging task, especially when it involves animations. If you’re developing a breathwork exercise application in Kotlin for Android, you might face the complexity of handling animations for different steps based on a set duration. In this guide, we'll tackle the problem of repeating an animation a specified number of times while ensuring that each previous animation completes successfully. Let’s get started!

The Problem: Repeating Animations in Kotlin

In your project, you have a 2D array that represents various steps in a breathwork exercise along with their durations:

While you attempted to use a while loop to iterate through the array of exercises and animate a progress bar, you encountered a couple of issues:

The screen blacked out while the animation was running.

The animations did not wait for each other to complete; it displayed the last step much too early.

Let’s find a solution to this problem.

The Solution: Using Recursion for Sequential Animations

To properly sequence your animations, you can use a recursive function. This allows you to ensure that each animation completes before moving on to the next step in your array. Here’s how to implement this:

Step 1: Setup Your Variables

You need to define your variables for tracking the current exercise type and duration. Here’s an example:

Step 2: Create the Animate Function

Next, you will create a recursive function that initiates the animation for each exercise. Here’s how this function can be structured:

Step 3: Start the Animation

Finally, you will call your animate function where you need to start the animation sequence:

Conclusion

By using a recursive function, you can effectively manage the sequencing of animations in your Kotlin application. This approach guarantees that each animation completes before the next one begins, preventing issues like screen blackouts and premature displays of exercise steps.

Don't forget to test your application extensively to ensure a smooth user experience. Happy coding, and good luck with your breathwork exercise application! If you have further questions or need additional help, feel free to reach out.
