Question

问题1：当我点击登录按钮时我可以登录，给出状态。但是当我按下注销按钮时它没有注销。那么，我将如何从Facebook注销？

问题2：我有一个字符串str。我想在facebook的文本字段中传递它（就像我们按意图发送消息）。我该怎么做。

        @Override
        public void onFacebookError(FacebookError e, Object state) {
        }
    });
}

    }`

当我点击退出按钮时，它说： `

      08-14 14:46:59.849: D/Image Button(284): button Clicked
      08-14 14:46:59.869: D/Facebook-Util(284): GET URL: https://api.facebook.com/restserver.php? method=auth.expireSession&format=json
      08-14 14:47:00.399: D/Logout from Facebook(284): {"error_code":101,"error_msg":"Invalid application ID.","request_args":[{"key":"method","value":"auth.expireSession"},{"key":"format","value":"json"}]}

`

Answer 1

只需清除共享偏好并明确烹饪即可从Facebook退出

btnFbLogout.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {

        Log.d("Image Button", "button Clicked");
        Util.clearCookies(youractivity.this);

        // your sharedPrefrence
        Editor editor = context.getSharedPreferences("MYFB_TOKEN",    Context.MODE_PRIVATE).edit();
        editor.clear();
        editor.commit();
    }
});

OR

请参阅此How can i logout from facebook when i click logout button

Answer 2

使用它对我有用

facebook.logout(this);

在Facebook SDK Facebook.java

中

public String logout(Context context) throws MalformedURLException, IOException {
   Util.clearCookies(context);
   Bundle b = new Bundle();
   b.putString("method", "auth.expireSession");
   String response = request(b);
   setAccessToken(null);
   setAccessExpires(0);
   return response;
}
