I'm using ContextCompat.getExternalFilesDirs to get a list of storages in android.
It shows up my devices internal storage path and sdcard path.
In Android 6,
you can format the sd card as "internal", called adopted storage.
When checking ContextCompat.getExternalFilesDirs it only returns one single path.
How would I know if this single path given is a internal storage or internal storage+adopted sd card? Is there a way to find out?

getExternalFilesDir(null) is returning the path of the emulated sd card i.e internal to the phone but not the path removable sd card
how i can find the data directory of app on removable storage
'External' means not internal and internal means private if we translate Android English to real life English. External storage is the place that all apps can access and use.
Since the question is a bit vague then the answer must be.
SD card can be mapped to internal storage or external storage, but this is fairly new technology.
If you want to access SD card using in versions earlier than Android 5.0 (API 21) then you can use Environment.getExternalStorageDirectory();
Otherwise you must use Storage Access Framework to do it.

Find location of a removable SD card

Long time iOS developer, advanced Android programmer (but not as advanced as I thought.. LOL)..
Trying to understand Android device storage options. On my android device I have an 14Gig SD Card.
When I write code
String strDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS)+ File.separator + "MyFolder";
it gets placed in a "Documents folder" on the internal device (when viewed with File Manager).
The path appears to be
storage/emulated/0
and my sd card (acording to the File Manager) is
storage/extSdCard
Why does Environment.getExternalStoragePublicDirectory give me a path to my intneral card?
What am I missing that gets me to a path to store files to the external card. I think I understand part of this is do to OS changes in SD Card access in 4.1 but not sure what I'm missing.
I've read through Environment.getExternalStorageDirectory does not return the path to the removable storage and still not clear. My app currently stores files using getExternalStoragePublicDirectory, however my users are requesting they have the option of storing it on the SDCard instead?
Why does Environment.getExternalStoragePublicDirectory give me a path to my intneral card?
Because external storage is not removable storage. Neither of those are internal storage.

On Android 4.4+, either use the Storage Access Framework (to allow the user to choose a storage location, including removable storage, Drive/Dropbox/other cloud providers, etc.), or use getExternalFilesDirs() on Context. The latter method returns a File[] — if there are 2+ elements in the array, all but the first are locations on removable storage that you can read from and write to. You cannot write to arbitrary locations on removable storage on devices that ship with Android 4.4+.
I've an application on the Play Store, and a user sent me a bug report saying that on his device the external sdcard is not listed in the external storage device list, though is mounted and accessible at /mnt/external_sd
I have a dialog listing folders and start directory is Environment.getExternalStorageDirectory().
After some clicks to get to the parent folder, the /storage folder is reached and getParent() returns null.
Which starting folder should I set to have access to the full storage structure?
EDIT:
As a workaround I am adding in my app preference the ability to choose if the storage root directory should be Environment.getExternalStorageDirectory() or hardcoded /mnt.
Comment/answer if there are best alternatives.
Get external storage parent folder on android
By external storage, I am assuming that you meant micro SD card storage.
external sdcard is not listed in the external storage device list,
though is mounted and accessible at /mnt/external_sd
You cannot access SD storage by using Environment.getExternalStorageDirectory() method.
Before API level 19, there was no official way to store in SD card. But, many could do it using unofficial APIs.
Officially, one method was introduced in Context class in API level 19 (Android version 4.4 - Kitkat).
File[] getExternalFilesDirs (String type)
It returns absolute paths to application-specific directories on all
shared/external storage devices where the application can place
persistent files it owns. These files are internal to the application,
and not typically visible to the user as media.
That means, it will return paths to both Micro SD card and Internal memory. Generally, second returned path would be storage path of micro SD card.
The Internal and External Storage terminology according to Google/official Android docs is quite different from what we think.
I'm using mergStoragePath("pictures") to get the path where to save pictures on Android. It works fine when the SD card is present but in a devices without an SD card, it points anyway to:
/mnt/sdcard/Pictures
Is there a way to get to have mergStoragePath to point to internal storage?
Not at present. The function is for external storage paths.
I got the both the external and internal(phone memory ) SD card in listing in my application
but along with that i got some more folder and i don't want them so how can i limit to external and internal SD card only in listing...
i provided the root directory which is /storage and it displays whole the folder...
or can some one tell me how to get external sd card programmaticaly
i have tried the usual way File file = Environment.getExternalStorageDirectory();
given by android but it returned only internal path .
Environment.getExternalStorageDirectory() it returns sd card path but depends on the device
for better under standing check Find an external SD card location
