Answer 1

Sie FacebookSdk.isFacebookRequestCode() wenn der Anforderungs-Code von Facebook ist zu überprüfen, schreiben können.

protected void onActivityResult(int requestCode, int resultCode, Intent data) 
    super.onActivityResult(requestCode, resultCode, data); 
    if (FacebookSdk.isFacebookRequestCode(requestCode) { 
     // Facebook 
     callbackManager.onActivityResult(requestCode, resultCode, data); 
    } else if (requestCode == RC_SIGN_IN) { 
     // Google 
     GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data); 
     handleResult(result); 
    } 
}
