预加载进不去啊

private void start() { L.i("开始预加载：" + mPosition); Log.d(TAG, "start: >>>"+"开始预加载aaa"); Toast.makeText(MyApplication.getAppInstance(), "开始预加载", Toast.LENGTH_SHORT).show(); HttpURLConnection connection = null; try { //获取HttpProxyCacheServer的代理地址 String proxyUrl = mCacheServer.getProxyUrl(mRawUrl); Log.d(TAG, "start: >>>"+"开始预加载proxyUrl"); Log.d(TAG, "start: >>>"+proxyUrl); URL url = new URL(proxyUrl); connection = (HttpURLConnection) url.openConnection(); connection.setConnectTimeout(3000); connection.setReadTimeout(3000); InputStream in = new BufferedInputStream(connection.getInputStream()); Log.d(TAG, "start: >>>"+"进行预加载"); Toast.makeText(MyApplication.getAppInstance(), "预加载。。", Toast.LENGTH_SHORT).show(); int length; int read = -1; byte[] bytes = new byte[8 * 1024]; //读到bytes数组里面去 while ((length = in.read(bytes)) != -1) { read += length; //预加载完成或者取消预加载 if (mIsCanceled || read >= PreloadManager.PRELOAD_LENGTH) { L.i("结束预加载：" + mPosition); Log.d(TAG, "start: >>>"+"结束预加载"); Toast.makeText(MyApplication.getAppInstance(), "结束预加载", Toast.LENGTH_SHORT).show(); break; } } if (read == -1) { //这种情况一般是预加载出错了，删掉缓存 L.i("预加载失败：" + mPosition); Toast.makeText(MyApplication.getAppInstance(), "预加载失败", Toast.LENGTH_SHORT).show(); File cacheFile = mCacheServer.getCacheFile(mRawUrl); if (cacheFile.exists()) { cacheFile.delete(); } } } catch (Exception e) { L.i("异常结束预加载：" + mPosition); Log.d(TAG, "start: >>>"+"异常"); Toast.makeText(MyApplication.getAppInstance(), "异常结束预加载", Toast.LENGTH_SHORT).show(); } finally { if (connection != null) { connection.disconnect(); Log.d(TAG, "start: >>>"+"异常"); } } } 这个方法走不完

走不完，没有异常信息么，网络错误或者是io读取错误之类的
