Question

我在这里遇到这种情况：

我的LoginActivity，从FacebookActionBarActivity扩展，从名为Session的自定义类的实例运行login方法：

@Override
protected void onFacebookLogin(final GraphUser facebookUser, com.facebook.Response response) {

    User user = new User(this, facebookUser);
    Session preSession = new Session(this, user);

    preSession.setCallback(new Response() {
        @Override
        public void onSuccess(Message m) {
            Log.i("LoginOk", "Yeaaaaaaaaah!: " + ((Session) m.getData()).toQueryString());
            hjClient.setSession((Session) m.getData());
            Intent i = new Intent(LoginActivity.this, MainActivity.class);
            i.putExtra("hjClient", hjClient);
            startActivity(i);
        }

        @Override
        public void onError(Message m) {
            //closeFacebookSession();
            if (m.getData() instanceof Exception) {
                ((Exception) m.getData()).getStackTrace();
            } else {
                Log.i("onError", m.getData().toString());
                Toast.makeText(LoginActivity.this, m.getDescription(), Toast.LENGTH_LONG);
            }
        }
    });

    preSession.login();
}

Session.login（）是这样的：

public void login() {

    RequestAsyncTask request = new RequestAsyncTask(getContext(), new Response() {
        @Override
        public void onSuccess(Message m) {
            try {
                Log.i("onSuccess login", m.getData().toString());
                JSONObject jsonObject = new JSONObject(m.getData().toString());
                // Si no hay un atributo code o el atributo code es 0 entonces el mensaje
                // desde el servicio es un OK
                if (!jsonObject.has("code") || jsonObject.get("code").equals("0")) {
                    if (getCallback() != null) getCallback().onSuccess(new Message(new Session(jsonObject)));
                } else {
                    onError(new Message(jsonObject));
                }
            } catch (Exception e) {
                onError(new Message(e));
            }
        }

        @Override
        public void onError(Message m) {
            if (getCallback() != null) getCallback().onError(m);
        }
    });

    request.execute("method=sessionLogin&" + toQueryString());
}

它创建一个RequestAsyncTask实例。 RequestAsyncTask从Java本机AsyncTask扩展并处理响应消息。这是RequestAsyncTask：

public class RequestAsyncTask extends AsyncTask {

Context context;
String url;
List<NameValuePair> params;
Response callback;

// constructor

public RequestAsyncTask(Context context, Response callback) {
    super();
    setContext(context);
    setCallback(callback);
}

// methods

@Override
protected Object doInBackground(Object[] params) {
    try {
        HttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost(getUrl());
        setParams(params[0].toString());
        post.setEntity(new UrlEncodedFormEntity(getParams()));
        return client.execute(post);
    } catch (Exception e) {
        // This Exception will be catched on onPostExecute and it will throw another Exception
        return e;
    }
}

@Override
protected void onPostExecute(Object o) {
    if (getCallback() != null) {
        Log.i("postExecute", o.toString());
        if (!(o instanceof Exception)) {
            try {
                String httpResponse = new BasicResponseHandler().handleResponse((HttpResponse) o);
                //JSONObject jsonResponse = new JSONObject(httpResponse);
                //getCallback().onSuccess(new Message(jsonResponse));
                Log.i("httpResponse", httpResponse);
                getCallback().onSuccess(new Message(httpResponse));
            } catch (Exception e) {
                Log.i("postExecuteRrror", e.toString());
                getCallback().onError(new Message(e));
            }
        } else {
            Log.i("Error en llamada", ":D");
            getCallback().onError(new Message((Exception) o));
        }
    }
}

我的问题是我在登录方法中启动的RequestAsyncTask实例的PostExecute方法上收到了NetworkOnMainThreadException。

这是StackTrace：

我做错了什么？有人能帮助我吗？

Answer 1

首先，这不是Java堆栈跟踪。

其次，将所有您的网络I / O移至doInBackground()。这包括您的handleResponse()电话。

在onFacebookLogin里面的AsyncTask里面的NetworkOnMainThreadException
