WIFI网络和移动网络同时打开，在下载过程中，关闭WIFI网络，此时系统关闭WIFI网络同时切换到移动网络，在此过程，出现以下异常，出现异常的语句是is.read(buffer)，代码段如下：

try{    while ((len = is.read(buffer)) != -1) {        if(!CommonUtils.isDownloadAvailable()) {            Logger.v(TAG, "Download operation is unavailable, stop down.");            break;        }        if(!running) {            Logger.v(TAG, "Down is cancelled, stop down.");            break;        }        offset += len;        file.write(buffer, 0, len);        sendMessage(DownMessage.MSG_UPDATE, len);    }}catch(IOException e) {    Logger.e(TAG, "Catch IO exception when read data from input stream.", e);    throw e;}

Catch IO exception when read data from input stream.
