The problem:
Caused by: java.lang.IllegalArgumentException: the name must not be empty
Inside AsyncTask you use accountName variable:
token1 = GoogleAuthUtil.getToken(Web_view_demo.this, accountName, mScope);
But variable is an instance member of Web_view_demo class. It is set once to an empty string, and to nothing else later:
String accountName="";
And in onCreate method, when you do:
final String accountName = intent.getExtras().getString("accountName");
you don't set value to instance member variable named accountName, but you create a new variable, visible only inside onCreate method. If you wanted to set the instance member variable, then change previous line to:
accountName = intent.getExtras().getString("accountName");
