Why is my emulator screen blank after connecting to it?
That means you have to wait a little longer
no its just white i uploaded wrong image
its now black
yes I understand it's not an error, it's just a few problems, the first problem you have to wait a little longer, second you have to remove a few pages on your chrom, third you should refresh your mit app inventor page first.
Please choose which one you want to do, I recommend you to refresh your mit app inventor page.
