Environment.getExternalStorageDerictory() return path to internal memory

Help me, please. My problem:
I have path /storage/sdcard0. It's internal memory on my device.
/storage/sdcard1 - path to SD.
Functoin
Environment.getExternalStorageDerictory()
return path /storage/sdcard0. How can I get path to my SD?

As pointed by Android doc :
Environment.getExternalStorageDirectory();
will return the primary external storage.
If you want to get the removable sd card path, you can read the /proc/mounts file to get the mounted medias since the path may vary from each device.

Where in Android file system are directories created?

I am working on Android app that has to save data to files. To make the files accessible for all apps and also transfer to computer through USB, the files should be saved in a folder called "ABC". I manually created the folder "ABC" on both external storage card and internal storage. I was able to get full path of that folder on external storage card through code and was able to write and read from it.
String path = Environment.getExternalStorageDirectory().toString() + "/ABC";
But the internal storage turns out to be more elusive because I could not get the full path of "ABC" folder on the internal storage. Is there a way to programmatically determine where folders are created on internal storage? Generally, under what partion are folders created on internal storage in Android?
Edit:
Internal storage - I mean non-removable storage
External Storage - I mean Removable storage

I manually created the folder "ABC" on both external storage card and internal storage.
You might have created this directory on external storage. Unless you are testing on a device or emulator, you did not create this directory on internal storage, as you do not have access to it. A "card" would imply removable storage, which is something else entirely, for the vast majority of Android devices.
I was able to get full path of that folder on external storage card through code and was able to write and read from it.
Your code is for external storage. On very few devices is that a "card".
But the internal storage turns out to be more elusive because I could not get the full path of "ABC" folder on the internal storage.
There is no "ABC" folder on internal storage, insofar as you cannot create a /ABC directory off of the device root, or even off of /data. You can only work for your app's portion of internal storage, using methods like getFilesDir(). And, again, unless you are testing on an emulator or a rooted device, you have no means of creating such an "ABC" directory by hand.
Is there a way to programmatically determine where folders are created on internal storage?
Um, well, you are certainly welcome to examine the path in the File object that you created to point to some location (e.g., new File(getFilesDir(), "ABC")).
Generally, under what partion are folders created on internal storage in Android?
/data.

How Do I write files to removable SD card (not external SD card) in KitKat?

Is there any method to get path to removable SD - card in API > 19 in Android?
Like for external SD card we have Environment.getExternalStorageDirectory();
Do we have something like that for removable SD card?
For instance, Galaxy S4 has 2 SD cards - one is built in SD card that is detected by Environment.getExternalStorageDirectory();
And another is optional, but if user insert it - how do I get a path to it by some method? And if there a method to know if it's mounted - plz also let me know

No there is not a reliable way to determine the path to the removable micro SD card. Even getExternalFilesDirs() does not do that on the two of my kitkat devices. You have to ask the user to indicate the exact path.

Environment.getExternalStorageDirectory(); gives you just what you want! The term "external" is a bit misleading though.
EDIT:
It gives you the directory of both sd cards!
You have to chose one by doing:
File storageDir = new File("/mnt/");
if(storageDir.isDirectory()){
String[] dirList = storageDir.list();
//Select card here
}

Get external sdcard in android phone

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

How to save files at phone storage

I want to save files to the device memory when SD card is inserted into the phone. Calling
Environment.getExternalStorageDirectory();
returns SD card folder located at mnt/sdcard.
Phone storage folder is located at mnt/sdcard2. Is there a way to get path to mnt/sdcard2 programmatically to download files there?
