title: Opening a file within my app using one of the pre-installed programs
body: <p>I had searched through different questions here but still didn't get how to approach it.</p>
  
  <p>So, basically, I have a file in my app that is displayed as if in file explorer, consequently, when user clicks on it - i want to open it using preinstalled program. Say, I want to open a pdf file with a  preinstalled pdf viewer. How do I approach this? If there any "automatic" solutions when you just give android a file path and its type and it offers you programs it can be opened with?</p>
  
  <p>Thanks xx</p>
