Open Specific Directory Using Storage Access Frame

Question

I'm currently able to obtain a file URI by opening the Lollipop file picker using the code below:

            Intent intent = new Intent();
            intent.setAction(Intent.ACTION_OPEN_DOCUMENT_TREE);
            startActivity(intent);

The file picker opens either at the root of Internal Storage or the last directory that I opened. How can I make the file picker show the contents of a specific directory? For example, I might want the file picker to show the contents of the Download folder after launching like in the picture below.

Use the Environment class which has methods like getExternalStorageDirectory() or getDataDirectory() https://developer.android.com/reference/android/os/Environment.html.

If the images are stored in a variable, grab them from that path:

private static final String fileName = Environment
            .getExternalStorageDirectory().getAbsolutePath()
            + "/pathToFile.jpg";
