Android app that updates Google spreadsheet

Question

I want to create an android app that allows multiple users to connect to a Google spreadsheet enter data into this single sheet through the app. Would I have to create a public sheet? If so would it require authentication or just a url of the sheet. If it is private sheet how what is required for authorization. I have read about the spreadsheet API but I don't where to start. Which would be easier a public or private sheet. Any guidance about how to go about this is welcome

Answer 1

You could use google-apps-script or the google-spreadsheet-api 3.0 (GData). But I suspect the google-spreadsheet-api is what you want. Google-apps-script is like VBA and runs on google servers.

For GData, the CellDemo.java gives a good overview of the features. https://gdata-java-client.googlecode.com/svn-history/r51/trunk/java/sample/spreadsheet/cell/CellDemo.java

Note: there is no INSERT row, only APPEND row. with GData - google-spreadsheet-api 3.0

I have never used a public sheet, not sure. For a private sheet, you need OAuth2 or an Application password.
