I try to read JSON from a website, and display the data in an Kodular App
So far this is the JSON Part:

I am reading in the forum since hours, and cant find the solution.

This is the corresponding JSON Data:

Since i seem to be too dumb to understand JSON and Kodular, i kindly ask for your help in how to display the data “title” and “artist” within a normal label.

Currently the app throws the following error at startup:
com.google.appinventor.components.runtime.util.YailDictionary.walkKeyPath(com.google.appinventor.components.runtime.util.YailObject,java.util.List)’ has wrong type (java.lang.String) (java.lang.String cannot be cast to com.google.appinventor.components.runtime.util.YailObject)

Many thanks for a response.
The next problems i will try to solve on my own again.

Thank you for your effort in this.

Best regards

what kind of help do you expect without providing the full api?

#3

What do you exactly mean with api?
What do you want to see at this point?

#4

how do you get this json result? via url? if so just share with us a sample

Because your json structure is seems to be incomplete
