【问题描述】：
我面临这个问题，我们的应用程序在结帐过程中随机崩溃，这种崩溃仅发生在棒棒糖上，其他版本运行正常。日志猫中除了 Fatal Signal 之外没有任何信息。这个问题也不能在模拟器上重现，它只发生在运行棒棒糖的设备上。
我重构了网络调用，现在我得到了 OpenGL 渲染器：刷新缓存问题。这发生在发出一些截击请求之后。
06-22 18:48:29.876 24145-24216/com.pangea.android.debug D/OpenGLRenderer﹕ Flushing caches (mode 0)
06-22 18:48:29.877 24145-24157/com.pangea.android.debug A/libc﹕ Fatal signal 11 (SIGSEGV), code 2, fault addr 0x12c7c000 in tid 24157 (FinalizerDaemon)
对于网络堆栈，我使用 Volley 和 OkHttp
Volley 请求是简单的 get 请求。
对于如何获取有关崩溃的更多信息有什么建议吗？
这里是创建连接的示例代码：
protected HttpURLConnection createConnection(URL url) throws IOException {
HttpURLConnection connection = new OkUrlFactory(mClient).open(url);
return connection;
}
private HttpURLConnection openConnection(URL url, Request<?> request) throws IOException {
HttpURLConnection connection = createConnection(url);
int timeoutMs = request.getTimeoutMs();
connection.setConnectTimeout(timeoutMs);
connection.setReadTimeout(timeoutMs);
connection.setUseCaches(false);
connection.setDoInput(true);
// use caller-provided custom SslSocketFactory, if any, for HTTPS
if ("https".equals(url.getProtocol()) && mSslSocketFactory != null) {
((HttpsURLConnection) connection).setSSLSocketFactory(mSslSocketFactory);
}
return connection;
}
这里是日志：

【问题讨论】：
-
你有一些代码可以给我们看吗？很难猜出你在做什么以及堆栈在哪里。我的第一个猜测是生命周期问题，但这只是猜测。
-
Kalem，我从 HttpStack 添加了一些代码。关于如何进一步缩小问题范围的任何建议。谢谢。
-
如果你把所有的东西都放在一个 AsyncTask 里面就好了
