これは私のGoogleのサインインページです：Google SigninアクティビティのどこからAsyntaskを呼び出しますか？

私は私のAsynTaskを呼び出す必要がありますどこ私は混乱していますか？ acct.getEmail()私はhandleSigninResult()を呼び出す必要がありますが、私が電話する場合は、AsynTaskが呼び出され、アプリを開くたびに呼び出されます。実際には私は最初のログイン時にAsynTaskに電話する必要があります...何を考えていますか？
fetchUserdataServerAsync mfetchUserdataServerAsync= new fetchUserdataServerAsync(acct.getEmail());
mfetchUserdataServerAsync.execute();
