The same code is working fine in Android O. new File(file.getParent()).mkdirs(); output = new ObjectOutputStream(new FileOutputStream(file)); output.writeObject(obj); I am able to read the files from the same device(Memory Card), but when I try to write the file, it is throwing Permission Denied exception.
