我正在测试适用于 Android 的新 Firebase 库，不幸的是它不起作用，这是我放在 onCreate MainActivity.method 上的代码：

Firebase ref = new Firebase("https://mydatabase.firebaseio.com/");

    // Read data and react to changes
    ref.addValueEventListener(new ValueEventListener() {

        @Override
        public void onDataChange(DataSnapshot snap) {
            Log.e("FIREBASE", snap.getName() + " -> " + snap.getValue());
        }

        @Override public void onCancelled() { }
    });

输出：没有显示消息和调试错误：

PS：我把 INTERNET 权限放在 AndroidManifest 文件上。

PS 2：我下载了聊天示例，但它也不起作用。

这看起来像是 Android 2.3 的 SSL 实现的问题。我们正在对围绕它工作的库进行更新。您可以尝试在版本 >= 3.0 的模拟器上运行您的应用程序吗？

我们刚刚发布了该库的新版本（v1.0.2）。你可以试一试，看看它是否能解决问题？它包括一些 Android SSL 限制的解决方法。
