Recently, many developers running the NIA (Now in Android) app on an emulator encountered the following error message:

[[See Video to Reveal this Text or Code Snippet]]

This issue usually arises when there is a mismatch between the Android API level your emulator is using and the API level compatible with the libraries and methods used within your app.

The Cause of the Problem

In this specific case, the error occurred while attempting to run the NIA app on an emulator configured with the TIRAMISU API, which corresponds to Android API level 33. However, it seems that the method getOnBackInvokedDispatcher() was not recognized, likely due to compatibility issues between the app's dependencies and the API level being used.

Solution Steps

Fortunately, the fix for this error is straightforward. The solution involves adjusting the Android API version of your emulator to ensure compatibility with your application. The steps to achieve this are detailed below:

Step-by-Step Instructions

Open Device Manager:

In Android Studio, begin by navigating to the Device Manager. This can be found in the tools or by searching for it.

Select the Emulator:

Locate the emulator device where you are facing the error. Click on it to open up its settings.

Update the API:

Change the API level from TIRAMISU (API 33) to API 32. This adjustment has been effective for many developers facing similar issues.

After adjusting, make sure to save the configuration.

Run the App Again:

Now, attempt to run the app on the updated emulator. With the updated settings, it should work smoothly without encountering the NoSuchMethodError.

Conclusion

Remember: Keeping your development tools updated and regularly checking API compatibility can save you time and frustration in the long run!

Happy coding!
