How to Do this ?

2

You know there is already a Spreadsheet component for Google Sheets, right?

3

yes i know.there are lots of spreadsheet extension available. i am not doing this for launching aix file.

4

so if user want to use your extension, they have to add another Web component?

5

No . Its only access class object . not whole component.

6

Thay dont need to add Web Component. :rofl:

then what is use of extension :rofl: :rofl: :rofl:

7

what you need is class java.net.HttpURLConnection

8

i dont know about java.net.HttpURLConnection

9

Just make your own event to return output?

10

But how i knows ! The event is fired !

All of the source code for App Inventor is open source on GitHub. You should probably take a look at the following two files:

  • appinventor/components/src/com/google/appinventor/components/runtime/Web.java
  • appinventor/components/src/com/google/appinventor/components/runtime/Spreadsheet.java

to see how they handle the asynchronous processing and handling of events.
