I am wondering if there is an updated version of this above mentioned document. (/googlesheets-api-setup.html). I have gone through and through, and either am on a different planet, or this needs some updating. I get the same error messages;
invoke: no method named `ReadColumn' in class com.google.appinventor.components.runtime.Spreadsheet
or
invoke: no method named `AddColumn' in class com.google.appinventor.components.runtime.Spreadsheet
I'm sure there must be a simple solution I have overlooked.
Any guidance shall be taken seriously and appreciatively
It was all about with whom I was sharing the app. I was in the wrong gmail account whilst running the app.
I figured it out, but thanks ABG for the list of documents. It was a good read
