title: Sign out from google and facebook in android application
body: <p>I have integrated google and facebook sign up using their respective methods. But after successful signing, I want to open different activity and similarly user can go to various different activities. I have used action bar where I am giving an option to sign out from either of the account that the user has logged in. How could I sign out the user when I am in different activity then the main activity. I am getting an exception and I am not able to pass apiclient reference (for google) and session reference (for facebook) to another activity. Please help. 
  Thanks in advance.</p>
