Android Studio Problem To Create My Apk File

Hi Boxers, a few days ago i created an APK File in Android Studio to test my Game on my Android Tablet and everything works fine.
Now today i filled in my BB File my Store identifier, my admob and chartboost IDs into the advertisement section.

And now when i open my already exported BB File in Android Studio, it shows me this errors.

Look at the screenshot at the bottom and on top, theres a red cross at APP.

I really don't know where i can find what's wrong there!

 

Try this way.

 

Hello,

I had the same issue:

1. Check your antivirus that is not blocking Aapt2.exe
2. Make sure the project folder does not have a long name

The above solved my issues.

Cheers !
