Call TinyWebDB GetValue

MIT App Inventor Help

Hi,
Can the call TinyWebDB GetValue be used more than once in an app?

If this is not allowed, how to share information with a few users of an app when the shared information is to be updated frequently?

Please advise.

Thank you.

sure, why not?

A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook http://www.appinventor.org/book2 ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.
There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro and the aia files for the projects in the book are here: http://www.appinventor.org/bookFiles
How to do a lot of basic things with App Inventor are described here: http://www.appinventor.org/content/howDoYou/eventHandling .

Also do the tutorials Our Tutorials! to learn the basics of App Inventor, then try something and follow the Top 5 Tips: How to learn App Inventor

Thanks Taifun.

The reason I asked this is because my app showed a warning when I tried to put another(second in my app) within a "when LocationSensor.changed" event.

I think this could be the reason for the warning since the "call TinyWebDB GetValue" is triggered too rapidly for the web to respond. The time interval for the LocationSensor was 60,000ms.

Am I correct?

you only can have one LocationSensor.Changed event... same for all othere events

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.
