I list a directory construction of Android.
I find the directory are same when list directory with these path /sdcard, /storage/sdcard0, /storage/emulated/legacy/and storage/emulated/0/, why?
The function
Environment.getExternalStorageDirectory()
can return /storage/emulated/0, I hope to return /storage/extSdCard/, which funation should I use?In my android mobile phone, the /storage/extSdCard/ point to a removable SD card, does the SD card belong to External Storage ? You know storage/emulated/0/ point to my phone memory Card! What are different between extSdCard and External Storage ?
