I always get issue when i generate apk or build web

hello every one
i am trying to built my first app with your amazing tool
but unfortunately when i try to generate apk or build web
i always get issue like this one


it is so simple app with 2 page and button

at the first i tried WebView app to display my site and it worked but this time not work at all

and i have another question
what is the benefit of first page how to disable it
i don’t need this black page at first of all my app
i dont see any important benefit from it

thanks sooo much

please check the assembly now, should work

the first page for animation, you can set the opening after 1 second and direct to the page you need

more than 1 hour


the build is working now
