Answer 1

Access tokens are short lived and only last for one hour this is not something you can extend.

What you need to do is take the refresh token and get a new access token.

example:

You take the refresh_token that you got from your initial request and HTTP Post it to: Note: grant_type=refresh_token

https://accounts.google.com/o/oauth2/token
client_id={ClientId}.apps.googleusercontent.com&client_secret={ClientSecret}&refresh_token=1/ffYmfI0sjR54Ft9oupubLzrJhD1hZS5tWQcyAvNECCA&grant_type=refresh_token

response

{
"access_token" : "ya29.1.AADtN_XK16As2ZHlScqOxGtntIlevNcasMSPwGiE3pe5ANZfrmJTcsI3ZtAjv4sDrPDRnQ",
"token_type" : "Bearer",
"expires_in" : 3600
}
