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

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?
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 ?
Root
sdcard
storage
storage/sdcard0/
storage/emulated/0/
storage/extSdCard/
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
}
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?
I am working on email application. My application will create some files in the Sd card.
I am using
Environment.getExternalStorageDirectory()
to store the files in SD card. But I have observed that some times when my device connected to my computer I am unable to access my files.
Please suggest what's the path I need to use so that my files must always accessible.
I want to store my files only in Sd card.
I think when the SD card is mounted you cannot access it.
