Hi Aryan. Welcome.
How to get your Location and put it on a map: here is one way How to put my location on a map
After you capture the latitude and longitude, store it .
You can determine and store to a TinyDB using code like this.
Exactly what you save and how you store the geocoordinates depends on what you want to do with them after you stored them. This code will save the location automatically when your GPS receiver decides you location changes. You can save using a Button instead.
Alternatively, you can save the latitude and longitude to a List and save that List to the TinyDB.
Here are some resources to help you learn to use the AI2 tools. 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 look here http://kio4.com/appinventor/index.htm and here http://www.imagnity.com/tutorial-index/ for more tutorials.
Is this what you wanted to know?
