How to convert any file format (.txt, .Doc) to an epub file in an Android application

Question

I am developing an application in which I have to read or write any book.

In android, so many libraries are available for reading any book, but I did not find anything for writing.

To read any eBook file, it must be in .epub format.

I have an editor in which I enter some text and after saving this file in any format, how can I convert this file to an .epub file.

Thanks in advance.

In android Java - the development language for creating APP, use Epublib (lib in java)

" doc" poi

epub:

package nl.siegmann.epublib.examples;

import java.io.InputStream;
import java.io.FileOutputStream;

import nl.siegmann.epublib.domain.Author;
import nl.siegmann.epublib.domain.Book;
import nl.siegmann.epublib.domain.Metadata;
import nl.siegmann.epublib.domain.Resource;
import nl.siegmann.epublib.domain.TOCReference;

import nl.siegmann.epublib.epub.EpubWriter;

public class Translator {
  private static InputStream getResource( String path ) {
    return Translator.class.getResourceAsStream( path );
  }

  private static Resource getResource( String path, String href ) {
    return new Resource( getResource( path ), href );
  }

  public static void main(String[] args) {
    try {
      // Create new Book
      Book book = new Book();
      Metadata metadata = book.getMetadata();

      // Set the title
      metadata.addTitle("Epublib test book 1");

      // Add an Author
      metadata.addAuthor(new Author("Joe", "Tester"));

      // Set cover image
      book.setCoverImage(
        getResource("/book1/test_cover.png", "cover.png") );

      // Add Chapter 1
      book.addSection("Introduction",
        getResource("/book1/chapter1.html", "chapter1.html") );

      // Add css file
      book.getResources().add(
        getResource("/book1/book1.css", "book1.css") );

      // Add Chapter 2
      TOCReference chapter2 = book.addSection( "Second Chapter",
        getResource("/book1/chapter2.html", "chapter2.html") );

      // Add image used by Chapter 2
      book.getResources().add(
        getResource("/book1/flowers_320x240.jpg", "flowers.jpg"));

      // Add Chapter2, Section 1
      book.addSection(chapter2, "Chapter 2, section 1",
        getResource("/book1/chapter2_1.html", "chapter2_1.html"));

      // Add Chapter 3
      book.addSection("Conclusion",
        getResource("/book1/chapter3.html", "chapter3.html"));

      // Create EpubWriter
      EpubWriter epubWriter = new EpubWriter();

      // Write the Book as Epub
      epubWriter.write(book, new FileOutputStream("test1_book1.epub"));
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}
