Hello All,
I am beginner to MIT. I am building a small project on using App Inventor.
Can any one help me to do this task. ?
Task: I would like to build a application it takes photo every one hour and save to the device with time watermark.
Thanks and awaiting for your valuable knowledge.
For this to work the app would have to be on the foreground constantly and keep running. This would drain the battery of you phone very quickly.
You could use this extension App Inventor Extensions: Camera | Pura Vida Apps
Hello Peter,
Device will be connected to the charge every time. And thanks for the extension. Let me check it out.
Can you give a free extension for this?
Welcome to the community
Unfortunately it looks like this is the only extension which is able to take pictures without user interaction
But you could write your own extension, create the functionality yourself and provide the extension for free to the community...
more information about how to create an extension see the App Inventor Extensions document
however that will be more advanced and will require some Java skills...
