运行的时候出现上面的问题，已经添加如下权限了
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
貌似是因为com.alipay.euler.andfix.util.FileUtil.copyFile(FileUtil.java:49) copyfile 的时候会拷贝到new File(getFilesDir(), "apatch"); apatch这个目录，但是这个目录并没有创建，代码执行前创建一下就不报错了，不知道是我代码哪里写的出问题了还是因为框架的bug，然而，不报错了，但是修复完好像没有效果。再找找原因，纠结。
