Question

设置

File cacheDirectory = new File(app.getCacheDir(), "network_cache");
        if (!cacheDirectory.exists()) {
            cacheDirectory.mkdir();
        }
        Cache cache = new Cache(cacheDirectory, CACHE_MAX_SIZE);
        OkHttpClient okHttpClient = new OkHttpClient();
        okHttpClient.networkInterceptors().add(new StethoInterceptor());
        okHttpClient.setCache(cache);

导致此异常，不可能被捕获：

    java.lang.NullPointerException: Attempt to invoke virtual method 'okio.BufferedSource com.squareup.okhttp.ResponseBody.source()' on a null object reference

这发生在okhttp 2.5和okhttp-ws 2.5上。使用okhttp 2.4和okhttp-ws 2.4，我们遇到了没有堆栈跟踪的崩溃

Answer 1

删除缓存修复了问题

OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.networkInterceptors().add(new StethoInterceptor());

当服务器拒绝连接时，带缓存的Websocket入队会导致崩溃
