Add storage permission to your project manifest file:

and ask the user to grant the permission like this:

int PERMISSION_ALL = 1;
String[] PERMISSIONS = {android.Manifest.permission.READ_EXTERNAL_STORAGE, android.Manifest.permission.WRITE_EXTERNAL_STORAGE};

add this method to your code:

public static boolean hasPermissions(Context context, String... permissions) {
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
        for (String permission : permissions) {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                return false;
            }
        }
    }
    return true;
}

and it is optional to override this:

    @Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case 1: {

            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                // permission was granted, yay! Do the
                // contacts-related task you need to do.
                Toast.makeText(getApplicationContext(), "permission was granted", Toast.LENGTH_SHORT).show();

            } else {

                // permission denied, boo! Disable the
                // functionality that depends on this permission.
                Toast.makeText(getApplicationContext(), "Permission denied", Toast.LENGTH_SHORT).show();
            }
            return;
        }
    }
}

now you can use the below code to access your application Download directory:

context.getApplicationContext().getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS);

Good Luck :)
