Facebook上的NetworkOnMainThreadException使用Phonegap 1.6.0登录

Question

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,在使用Android 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完全正常工作.我们正在使用位于此处的Phonegap Facebook插件和Cordova补丁.会发生的是,一旦我们尝试使用Android Honeycomb或更高版本的智能手机登录Facebook,该应用程序就会启动NetworkOnMainThreadException,因为主线程上不允许进行网络操作.此异常仅在Android Honeycomb或更高版本上引发,这就是我们在2.3.3上没有注意到的原因.调用FB.login()并且未达到回调时抛出异常.

我检查了各种线程和主题,但都非常模糊.我知道我必须在一个单独的线程中运行网络操作,但我不确定应该怎么做.线程似乎发生在Java中,但我根本就没有使用任何Java,所以在使用非我编写的代码进行修改之前,我想要一些帮助.

我将稍后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放在一个单独的线程中来解决错误.对于未来的读者,我将发布以下说明.

在ConnectPlugin.java,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();

这应该解决NetworkOnMainThreadException.
