Background processing

I have an App that posts messages to a website every few minutes. The App needs to continue running even if the user switches to another App. Is this possible with App Inventor? How?
Many thanks.

Try the itoo extension, read the complete thread and try the examples to learn how the extension works

You also can use the UrsAI2KeepAlive zip archive Ullis Roboter Seite/AI2 Keep Alive The archive contains the source code, the compiled binary for uploading to the App Inventor and a discussion of how Ullis' Foreground extensions work.

Several examples that show how this was done with gps are examples of the technique:
