Dear Sir/Madam,

For your information.

I'm new app inventor user.

I'm already created one app but its not installed in my Android phone. Why?

Please provide a more detailed explanation of what you are trying to achieve, what you have done so far, what works, what doesn't work...

Did you compile an apk ?

Did you install this to your phone ? (Either by using the QR Code or copying file over then installing it )
