I Compiled an Rapid Api extension, In Niotron IDE.
It’s giving me runtime error (undefined) In apk.
It’s blocks.
Here is extension.
SatwikGetExtensionnew.aix (9.2 KB)
Its source code.

I don’t know java.
I know web component do this job perfectly, but just want to work with these

I will but for now please.
I trying from yesterday. Yes with gpt. But getting error and arror and error.
Now I created the code from app inventor example code.
Currently getting this error.

I think you have to help me now?
Over here, in the @UsesLibraries, it should be like this:
@UsesLibraries(libraries = “okhttp-3.9.0.jar, json-20220924.jar”)
Ok.wait checking.
.
For counter error I use ( okio-1.13.0.jar )
Now getting.
Response not successful: 500, and app crashesh.
I used wrong (api-key,url,host) thats why it’s generating error 500.
I searched on gpt it’s say eternal server problem( I checked my blocks, I used default key that’s why I think it is generated error.
With correct parameters it is working fine.

Special Thanks.
-
@Xoma ( on app inventor huge collection of
example code. Help me to
understand code. And once
again.thank you for helping here also.) -
@Akshat_Rana ( thank you for replying on this
topic. Your to good person
liked your helping nature.) -
@vknow360 ( Thank you for your reply, due
to your reply I understand
basics of extension
Development.) -
chatgpt. Helped to solve errors.
As a B.A student this was really tuff for me.

What is the purpose of your extension?
Please provide also a short documentation about the methods and events
Taifun
) {Made for Rapid Api}
)Uses of this Extension:
No need to create List of headers.
)How it works here is the Example blocks. To parse Response data used (Jsontool extension. Provided by Techy Rakshak )
Please explain more… What is the Rapid API?
And why should we use the extension? What is the advantage to use this extension compared to just set 2 headers and use the web component?
