Android 10 Unable to open '/storage/emulated/0/: Permission denied
When reading the SD card data in Android10, it reported such an error. At first, I was confused, and the permission was also added. Why did it report no permission. Here is the new mechanism of Android, each application can only access the following path:
/storage/emulated/0/Android/data/<包名>/files
The files under the name of your own SD storage package cannot be accessed under other paths. Putting all access data under this path will not report an error.
