Date: 2017feb21 OS: Android Q. How can I find the second sdcard? A. One of these should work

String path1 = System.getenv("SECONDARY_STORAGE"); String path2 = System.getenv("EXTERNAL_SDCARD_STORAGE");

By the way, how to get the *first* sdcard:

Environment.getExternalStorageDir()

Alternate approaches:

Looked at everything call *card* below /mnt

Look for /sdcard and /extscard
