How to get the default directory of photo made by camera in android?

Question

I hope to get the default directory of photo made by camera in android.

I think that the Code A can do that, and /storage/sdcard0/DCIM is displayed in log,

but in fact, my photos made by camera are stored in the folder /storage/extSdCard/DCIM

How can I get the default directory of photo made by camera in android? Thanks!

Code A

File dir10 = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
Log.e("MainActivity", "getExternalStoragePublicDirectory() 10:" + dir10.toString());

It seems that the default storage location of photos made by camera is set by user, sometimes it's Memory card, somtimes it's SD card. I hope know which storage location the user selected for store photos made by camera.

Answer 1

Use getExternalStoragePublicDirectory() with parameter DIRECTORY_PICTURES

File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
File file = new File(path, "DemoPicture.jpg");

DIRECTORY_DCIM is the traditional location for pictures and videos when mounting the device as a camera.

DIRECTORY_PICTURES is Standard directory in which to place pictures that are available to the user.

Hope it helps !

Answer 2

1.This will work only if user didn't change the default Camera output Dir

As per documentation, There are two options

DIRECTORY_DCIM The traditional location for pictures and videos when mounting the device as a camera.

File musicDirectory = new File( getExternalFilesDir(Environment.DIRECTORY_DCIM));

DIRECTORY_PICTURES Standard directory in which to place pictures that are available to the user.

File musicDirectory = new File( getExternalFilesDir(Environment.DIRECTORY_PICTURES));

getExternalFilesDir() will return File object

you can refer here developer page

2. There is another trick you can do if you have atleast taken one pic taken in camera

String[] projection = new String[]{MediaStore.Images.ImageColumns._ID,MediaStore.Images.ImageColumns.DATA,MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME,MediaStore.Images.ImageColumns.DATE_TAKEN,MediaStore.Images.ImageColumns.MIME_TYPE};     
final Cursor cursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,projection, null, null, MediaStore.Images.ImageColumns.DATE_TAKEN + " DESC"); 
if(cursor != null){
    cursor.moveToFirst();
    //you can access last taken pics here. 
 }

Answer 3

Environment.getExternalStoragePublicDirectory is used to get directories on internal storage only.

To get the DCIM folder on your secondary storage (if exists) you need to follow this code:

String secondStorage = System.getenv("SECONDARY_STORAGE");
File file = new File(secStore + "/DCIM");
File[] listFiles = file.listFiles();
