Question

我有一个片段，我使用Async Http库进行API调用。

这是代码：

private void getPeers() {
    Log.i("REST", "getPeers");
    RestClient.get(RestClient.PEERS_URL, null, new TextHttpResponseHandler() {
        @Override
        public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
            Log.i("REST", "onFailure");
            stopRefreshing();
            if (statusCode == 0) {
                showNoConnectionError();
            }
        }

        @Override
        public void onSuccess(int statusCode, Header[] headers, String responseString) {
            Log.i("REST", "onSuccess");
            stopRefreshing();
            // Create arraylist from json
            peerArrayList = new Gson().fromJson(responseString, new TypeToken<List<Peer>>() {
            }.getType());
            // Show ListView
            populateListView(peerArrayList);
        }
    });
}

当我第一次调用getPeers（）时，一切正常。

第二次调用后，它会加载5-10秒然后超时。

这是2次调用后的日志：

如果我打电话一次，然后重新启动应用程序，它就可以了。当我连续两次调用它时，就会发生这种情况。

Answer 1

使用此方法代替RestClient。

 public static AsyncHttpClient getAsyncHttpClient() {
        return new AsyncHttpClient();
    }

在此Fragment中第二次调用API时出现ClientProtocolException
