How do I trigger phone call when the value in a database is 1?

2

you can't trigger a phone call programmatically without user interaction, the user always have to click a button

for a Google Play friendly method to start a phone call use the activity starter method, see also this thread in the old forum https://groups.google.com/d/msg/mitappinventortest/YZ6UN1fuA0k/cPIWFYjADwAJ

So, there is no way to trigger call or message automatically based on the data retrieved from database?

@Thulssss

What Taifun said in slightly different words is there is no way to trigger a call message other than by the device user making the call using the Phone component manually. AI2 apps cannot send a message or make a call by programming ( you cannot use the events of a component including the database controls to initiate a call or text message). Sorry.

You can send an eMail using a GoogleSheet . Here is a non-App Inventor 2 example: Create a mail merge with Gmail & Google Sheets  |  Apps Script  |  Google for Developers

If applications could make calls or send text messages themselves, many developers could use this to earn money by sending text messages or calling paid numbers.
