Good for you, hope they can fix the problem soon
I use a lot of extensions in my App and I can’t easily find which one causes the problem.
I’ll make a copy of the project, and I’ll try the remove the extensions one by one until I find the one that causes the issue
I’ll share the result here.
I found it !
It was EXO_PLAYER from DeepHost
I removed it and I was able the export the APK File
Now, I need a similar extension to play my online videos
Any suggestions

many devices cause app carshing when you use video player inside it, simply make html page with video embedding and use that in web viewer.

This doesn’t make sense to use Kodular Premium with this extension restrictions. Using alternative component/extension is not a valid solution for this issue while there’s lot of extensions used in a project.

Have a look into the errors/logs
there’s 5 extension causing the issue. These 5 are important for the whole project. How can I replace them. Everything was fine before the last update.
Sometime I suspect are all these issues are intentional?
It looks like you forgot to post the end of the log, which is the interesting part…

it seems that Kodular is caught in a bug spiral. If one bug is fixed, another one appears. When something like this happens to me when programming extensions, I usually start again from an earlier, safe working point. This will certainly be difficult with a huge program like Kodular. My advice is: make backups of your files. And if necessary, try loading them in another, more stable builder. I recommend the builder that starts with the letter N.

What the sense of using premium account even these issues not solved by kodular team ,
each and every time of kodular update issues occurs . are they not test update before releasing . i have more than 50 project every project giving same error d8 failed.

You’re definitely right, but it’s a maybe quick fix while kodular cleans up the mess it made.
We also found the problem, the Firebase authentication extension also causing the D8 build failed error.
You have the same problem as me
I wonder if you can solve it
Please tell me how to solve it
run d8 in this your case is Admod extension :), and if your have Download block in your project have d8 too.
To testing please export your aia file and make clone project, and delete extension one by one out your project to test

Add more 10 extension it will get fixed.
that’s crazy
If I want to create an APK with both extensions, I will fail using d8
If I test with GSMaxPlus only, it work!
Also if I test with GSMaxToolsPlus only, it work!!!
Do you know how this happens?
Hey Dev, 
if u use same library in tow extesntion u well got d8 failed
if u have 2 class with same name (class in ur app, or class from library) u well got d8 failed
Please send me the AIA file that will help me to fix the cause of the bug. My email - [email protected]
