Android Question Open App.. afeter install the apk

[nicieri]

Hi, I'm trying to install directly the apk in another phones...

When the app finish the installation I can see the buttons "ready" and "open".. but the button "open" is disabled...

Why?,.. My app.. hide the icon, etc.. this app will run only one time after install.. I need this button "enabled".. some idea?

When I debug my app directly to the phone, this run perfectly.

You are removing the main activity entry point to android in your manifest.
That´s the reason why you cant start it and the button is disabled.
