title: how to convert jpg to pdf in Android java
body: <p>I want to convert several .jpg files (taken using the device camera) to ONE .pdf file.
  I saw a lot of tools like iText, mupdf, PDFjet, pdjBox.</p>
  
  <p>Is there something more simple? (like an API ready for android?)</p>
  
  <p>Thanks.</p>
