Question

从Crashlytics我得到例外，我正在使用下载管理器下载文件：

这是代码：

 DownloadManager.Request request = new DownloadManager.Request(
                Uri.parse(videoURL));


        File folder = new File(dir + "" + File.separator + (isAudio ? AUDIO : IMAGES));
        if (folder == null) {
            return;
        }
   try {
                request.setAllowedNetworkTypes(
                        DownloadManager.Request.NETWORK_WIFI
                                | DownloadManager.Request.NETWORK_MOBILE)
                        .setAllowedOverRoaming(false)
                        .setTitle("Test")
                        .setNotificationVisibility(DownloadManager.Request.VISIBILITY_HIDDEN)
                        .setDescription(id)
                        .setDestinationInExternalFilesDir(context, isAudio ? AUDIO : IMAGES, fileName);
            } catch (IllegalStateException e) {
            } catch (Exception e) {
            }

                enqueue = downloadManager.enqueue(request);

这是来自logcat的堆栈跟踪：

我找不到原因，它在40多台设备上工作正常，只报告了一次崩溃，我也拒绝了申请许可，但工作正常。任何人都可以对它有所了解。我应该在try catch中使用put enqueue方法吗？
