ErrnoException：statfs failed：EACCES（Permission denied）＆amp;路径无效：/ mnt / sdcard

Question

我的Android应用使用Samsung SPen SDK 2.2。我有＆gt; 50个用户和＆gt; 3个月我没有收到任何崩溃报告，但今天我在Google Play开发者控制台中找到了一个。它来自三星Galaxy Note 3（Android 4.3），但有很多其他用户使用同一设备从未遇到过这个问题。

你知道崩溃的原因是什么吗？我甚至不知道如何在我的测试设备上重现它。

应用程序代码不适用于SD卡（不像

）

Environment.getExternalStorageDirectory();

，没有/ mnt / sdcard的硬编码路径等），它没有WRITE_EXTERNAL_STORAGE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：
