Issues with signing app on Android Studio

[Symbol_3D]

I am just at the end of my app development cycle but unfortunately I can't sign the app bundle to upload it to the play store. When I attempt to use the "Generate signed APK" function it throws up this error message after I've put in the details of the keystore and moved on:

Any help would be greatly appreciated, thanks for reading

The error stack trace you've posted points to a java.lang.AssertionError, which typically suggests that there might be an issue or a bug in the IntelliJ/Android Studio environment you are using. Here are some steps to potentially resolve this issue:

1. Update Android Studio:​

• Make sure you're using the latest version of Android Studio. Updates often include bug fixes.

2. Invalidate Caches and Restart:​

• Go to File > Invalidate Caches / Restart... > Invalidate and Restart.
• This clears the cache and restarts Android Studio, which could resolve the issue if it’s caused by a corrupted cache.

3. Review Keystore Details:​

• Double-check the details of the keystore you are using for signing. Ensure that the path, password, and alias are correctly entered.

4. Review Gradle Configuration:​

• Make sure that your Gradle configuration is correct, and that there aren’t any inconsistencies that might cause the signing process to fail.

5. Try Command Line:​

• Try signing your app using the command line. You can use the following command:

./gradlew bundleRelease

This will generate a signed app bundle.

6. Re-create Keystore:​

• As a last resort, you can try creating a new keystore and signing the app with it. Make sure you keep the details of the new keystore secure and backed up.

7. Check for Plugin Conflicts:​

• Disable any unnecessary plugins in your Android Studio to avoid conflicts that might be causing this issue.

8. Reinstall Android Studio:​

• If none of the above steps work, you might consider reinstalling Android Studio.

9. Check for External Reports:​

• Look for similar issues reported by other developers, as this might be a known bug, and there might be a workaround or a fix available.

10. Review Environment and Configuration:​

• Make sure your system’s environment variables and configuration settings are correct, as misconfigurations might lead to such errors.

I hope one of these solutions helps resolve the issue! Remember to always keep a backup of your work before attempting significant changes like reinstalling software or invalidating caches.

Welcome to AF @Symbol_3D. I moved your thread to the development area for best assistance.
Thanks for joining and I hope we can help.

Thank you for the replies, I went through them but unfortunately it didn't work out. However I did circumvent the process with the method shown in this video:

. It used command prompt to create a key rather than Android Studio and it works fine. I hope this helps anyone with the same issue.
