Answer 1

Reading & writing data on spread sheet is not an easy thing. I would suggest you go with WebView that might solve you issues. Here you might found some clue to do so

& here on Google.Apis.Sheets.v4 API's are

& Spreadsheets with C#

Accessing Google Spreadsheets with C# using Google Data API

I created the following Solution and it is working fine for me:

You Need to use JSON result from Google sheet, try to use the following steps:

1-Publish a google sheet to get an API link that returns JSON, like the following Sheet:

https://spreadsheets.google.com/feeds/list/1opP1t_E9xfuLXBkhuyzo5j9k_xBNDx0XKb31JwLP1MM/1/public/values?alt=json

2-You need to generate C# Classes from JSON, maybe you are able to use http://json2csharp.com To get the C# Classes and the RootObject.

3- Add The following Code:

   HttpClient client = new HttpClient();
   string URL = "https://spreadsheets.google.com/feeds/list/1opP1t_E9xfuLXBkhuyzo5j9k_xBNDx0XKb31JwLP1MM/1/public/values?alt=json";
   var response = await client.GetAsync(string.Format(url));
   string result = await response.Content.ReadAsStringAsync();
   RootObject root = JsonConvert.DeserializeObject<RootObject>(result);

From the root object, you will be able to access any cell value on the Google sheet.

Despite the fact that it really isn't a good idea to use Google Sheets as your online database, there are many better alternatives, if you want to access it from a Xamarin Forms app you can do it using the Sheets API
