Question

I am currently creating an application using Phonegap 1.6.0 and Sencha Touch 1.1. Recently, when testing on a smartphone with Android 4.0.4, we discovered that the Facebook Login doesn t quite work as expected. We are using the Phonegap Facebook Plugin located here with patches for Cordova. What happens is that, once we try logging into Facebook on a Smartphone with Android Honeycomb or higher, the application launches a NetworkOnMainThreadException because Network operations aren t permitted on the main thread. This exception is only thrown on Android Honeycomb or above, which is why we didn t notice it on 2.3.3. The exception is thrown when calling FB.login() and the callback is not reached.

我检查了各种线条和主题,但都非常模糊。我知道我必须用一个分泌线来运行网络操作,但 < 坚固> 我不清楚该如何做 < / 坚固 > 。串列似乎在爪哇发生, 但我根本不使用任何爪哇, 所以在用不是我写的代码来玩弄之前, 我希望得到一些帮助。

我稍后将努力缩小造成例外的部分,希望得到任何帮助。

我通过将 ConnectPlugin.java 的认证部分放在单独的线索中解决了错误。对于未来的读者,我将张贴以下说明。

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();
}

具有以下编码:

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();

这将修正 Network onMainThreadExpendion 。
