如何在Android Facebook Wall中发布消息？

Question

我正在使用此代码在android facebookwall上发布

Bundle parameters = new Bundle();


parameters.putString("message", string);
    try {
        mFacebook.request("me");
        mFacebook.request("feed", parameters, "POST");
        Toast.makeText(MainActivity.this,
                "Message posted to your facebook wall!", Toast.LENGTH_SHORT)
                .show();
    } catch (Exception e) {

        e.printStackTrace();

    }

但是在发布时出现此错误。

    Key format expected byte[] but value was a java.lang.String.  The default value <null> was      
    returned.
    Attempt to cast generated internal exception:
   // class cast exceptions
    java.lang.ClassCastException: java.lang.String cannot be cast to byte[]

试试这个参数。putString（“ message”，“写您的帖子以显示在墙上”）；
