android get real path by Uri.getPath()

This is what I do:

Uri selectedImageURI = data.getData();
imageFile = new File(getRealPathFromURI(selectedImageURI));

and:

private String getRealPathFromURI(Uri contentURI) {
    String result;
    Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
    if (cursor == null) { // Source is Dropbox or other similar local file path
        result = contentURI.getPath();
    } else { 
        cursor.moveToFirst(); 
        int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA); 
        result = cursor.getString(idx);
        cursor.close();
    }
    return result;
}

NOTE: managedQuery() method is deprecated, so I am not using it.

Last edit: Improvement. We should close cursor!!

Is it really necessary for you to get a physical path?
For example, ImageView.setImageURI() and ContentResolver.openInputStream() allow you to access the contents of a file without knowing its real path.
