Android ErrnoException:statfs失败：EACCES（权限被拒绝）&无效路径：/mnt/sdcard

我的android应用程序使用三星SPen SDK 2.2。我有超过50个用户，3个月以上没有收到任何崩溃报告，但今天我在谷歌Play开发者控制台中收到了一份。它来自三星Galaxy Note 3安卓4.3，但有许多其他用户使用相同的设备从未遇到过这个问题

你知道坠机的原因吗？我甚至不知道如何在我的测试设备上复制它

应用程序代码与SD卡不兼容

Environment.getExternalStorageDirectory();

，没有指向/mnt/sdcard等的硬编码路径，它没有写入外部存储权限。此外，该应用程序无法安装/移动到SD卡

崩溃报告包含以下堆栈跟踪：

你能发布你的代码吗？Hamid，我不知道是哪段代码导致了这个异常，我已经提供了我在开发控制台崩溃报告中看到的所有信息。发布你试图访问ExternalStorage的代码部分。感谢你的帮助，但是如果你再次阅读这个问题，您将看到，我没有使用此代码或任何其他代码访问SD卡/内部存储器。
