In my fragment java class there is an error coming in the getLastSignedInAccount in "this" statement following is the code:
GoogleSignedInAccount signInAccount = GoogleSignIn.getLastSignedInAccount(this); 
 if(signInAccount != null){
    name.setText(signInAccount.getDisplayName()); 
    mail.setText(signInAccount.getEmail());
   }
