我目前正在使用 Phonegap 1.6.0 和 Sencha Touch 1.1 创建一个应用程序。最近，在安卓 4.0.4 的智能手机上进行测试时，我们发现 Facebook 登录并没有像预期的那样工作。我们正在使用位于此处的 Phonegap Facebook 插件和 Cordova 的补丁。发生的情况是，一旦我们尝试在具有 Android Honeycomb 或更高版本的智能手机上登录 Facebook，应用程序将启动 NetworkOnMainThreadException，因为主线程上不允许网络操作。此异常仅在 Android Honeycomb 或更高版本上抛出，这就是我们在 2.3.3 上没有注意到它的原因。调用 FB.login() 时抛出异常且未到达回调。

我检查了各种主题和主题，但都非常模糊。我知道我必须在单独的线程中运行网络操作，但我不确定应该如何完成。线程似乎发生在 Java 中，但我根本没有使用任何 Java，所以在乱搞不是我写的代码之前，我需要一些帮助。

稍后我将尝试缩小导致异常的部分。任何帮助，将不胜感激。

我设法通过将身份验证部分ConnectPlugin.java放在单独的线程中来解决错误。对于未来的读者，我将在下面发布说明。

在ConnectPlugin.java中，替换：

try {
    JSONObject o = new JSONObject(this.fba.facebook.request("/me"));
    this.fba.userId = o.getString("id");
    this.fba.success(getResponse(), this.fba.callbackId);
} catch (MalformedURLException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (JSONException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

使用以下代码：

Thread t = new Thread(new Runnable() {
    public void run() {
        try {
            JSONObject o = new JSONObject(fba.facebook.request("/me"));
            fba.userId = o.getString("id");
            fba.success(getResponse(), fba.callbackId);
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
});
t.start();

那应该修复NetworkOnMainThreadException.
