所以我遵循了 facebook 开发网站中的教程页面,我有这个代码:

    import android.os.Bundle;
    import android.support.v4.app.FragmentActivity;
    import android.view.Menu;

        public class MainActivity extends FragmentActivity {

        private MainFragment mainFragment;

        @Override
        public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if (savedInstanceState == null) {
        // Add the fragment on initial activity setup
        mainFragment = new MainFragment();
        getSupportFragmentManager().beginTransaction()
                .add(android.R.id.content, mainFragment).commit();
    } else {
        // Or set the fragment from restored state info
        mainFragment = (MainFragment) getSupportFragmentManager()
                .findFragmentById(android.R.id.content);
    }
    }

        @Override
    public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
    }

}

这是片段类

}

所以我有所有代码在这两个页面中工作的意思 https://developers.facebook.com/docs/howtos/androidsdk/3.0/login-with-facebook/https://developers.facebook.com/docs /howtos/androidsdk/3.0/publish-to-feed/

出于某种原因,我可以登录,已经完成,但是现在当我单击共享时,它只会一直加载,直到我的 android 设备因为被冻结而要求我关闭应用程序,日志猫说 facebook.katana 没有响应,所以我该如何解决这个问题。与应用仪表板中的权限有关吗?或者有什么问题。我需要知道我是否做错了什么。在我重新开始并重新开始之前。

更新:将近 24 小时后,我终于在我的墙上收到了张贴的消息,所以这似乎是可行的,但 Facebook 有时似乎没有反应。
