Unable to view files obtained after compression

[Astha]

I'm using an Android wrapper over 7Zip-Jbinding and facing an issue with compressing files other than .txt.
I tried picking mp4 and .docx files from my assets folder(in Android project) and found that the zip is created sucessfully but when I tried opening the compressed files after extracting, I'm unable to do so seems the files are corrupted. However same is file with .txt files.

Also the obtained files are under directoy strtucre as that of asset folder from where I picked my files.

Can't we compress files other than txt using 7zip-JBinding?
or is it some issue at my end?

Let me know if you need more details from my end.

It works correctly with FileOutputStream with parameter 'true'.

result = item.extractSlow(new ISequentialOutStream() {
                        @SneakyThrows
                        public int write(byte[] data) throws SevenZipException {
                            FileOutputStream wr = null;
                            try {
                                wr = new FileOutputStream("c:\\Users\\1\\tt.pdf", true);
                                wr.write(data);
                            } catch (FileNotFoundException e) {
                                // TODO Auto-generated catch block
                                e.printStackTrace();
                            } catch (IOException e) {
                                // TODO Auto-generated catch block
                                e.printStackTrace();
                            } finally {
                                if (wr != null) {
                                    wr.close();
                                }
                            }
                            }
                            }
