It’s saying there
Package name contains illegal characters (only letters, numbers, and underscores are allowed)
No spaces too… Instead of ‘My Project’ rename your project to ‘MyProject’
Go to Project Settings > Android >
Application Display Name (app_name), project name if black
There you can put your project name with spaces like ‘My Project Something’
And that’s how it will be looking on Android App

i changed the name to this. and still i saw that error. is there any other way to fix it?
