Hola. He construido aplicaciones pero necesito que las mismas funcionen todo el tiempo. Aunque el teléfono haya entrado en stand by o cerrado la pantalla. ¿Alguien puede darme una ayuda?
App Inventor 2 cannot create apps that run as a Service. That means they cannot run in the background as you would like Adrian.
The best you can do is prevent the screen from closing using a Stay Awake routine .
Either use a Stay Awake block routine using a Notifier
or you use Taifun’s Tools Extension: https://puravidaapps.com/tools.php
Be aware using either an extension or a block routine drains your device battery rapidly . These work around methods are not running the app in the Background, they force the app to screen to stay open.
Hello Steve. Thanks for the answer. I have done that as an alternative.
Why can´t app inventor create apps that run as a Service?
Google has taken Android in a direction that makes the approach to services taken here unworkable
