Understanding the Problem with App Open Ads

As developers, we often confront issues when integrating ad services into our applications. One common problem arises with App Open Ads in Android applications developed using Kotlin. If you’ve ever faced the challenge where your ads do not display during the initial launch and only appear when resuming the app, you are not alone.

The crux of the issue lies in how and when you call your ad display function, particularly surrounding the onStart() and onResume() lifecycle events. In this guide, we’ll explore this problem and discuss a solution to ensure your ads show up correctly.

The Issue

In your application, you may be attempting to show ads in the onStart() method, but due to the asynchronous nature of ad loading, it frequently results in ads not being displayed when expected. Instead, they only appear upon resuming the application.

Key Observations

The showAdIfAvailable() method checks if an ad is loaded (isAdAvailable).

On the first launch, isAdAvailable is initialized to false.

The app fetches a new ad when isAdAvailable is false, but does not display it immediately.

This leads to a scenario where the user only sees the ad once they leave and return to the app.

Solution Overview

The solution here involves tweaking the way ads are fetched and shown in the onAdLoaded callback of your AppOpenManager class. Let’s break this down step-by-step.

Fetching and Displaying Ads

Modify the onAdLoaded Callback

When an ad is successfully loaded, the goal is to attempt to display it immediately. Here’s how you can adjust your onAdLoaded function:

Ensuring Safe Access to the Current Activity

Considering that the ad fetching process is asynchronous, you need to check if the current activity is still valid before trying to show the ad. Use Kotlin’s safe call operator (?.) to avoid any null pointer exceptions:

Why This Matters

This change ensures:

You are attempting to show the ad immediately after it loads, as intended.

Activity validity is checked before trying to display the ad, preventing potential crashes due to null references.

Conclusion

Integrating App Open Ads in your Kotlin Android application doesn't have to be problematic. By adjusting how and when you fetch and display your ads, you can enhance user experience and ad visibility significantly. Employing safe call techniques also ensures that your app runs smoothly without unexpected interruptions.

Feel free to implement these suggestions in your app and watch how they affect your ad display logic! If you encounter any further questions, don't hesitate to reach out. Happy coding!
