title: Choose file from downloads folder -> send it over bluetooth
body: <p>I have a problem that I've broken down into two main parts.</p>
  
  <p>1) Click button to pop up downloads folder. Choose a file from the downloads folder.</p>
  
  <p>2) Take that file that you just chose. Send it to a paired device via bluetooth.</p>
  
  <p>The bluetooth portion I believe won't be that bad given the resources and examples on here.</p>
  
  <p>But #1 I am having trouble figuring out how to tackle (kinda new to android). Are there any good tutorials/docs/links for accessing the downloads folder, picking a file and then using that file for later use for things such as file transfer/etc?</p>
  
  <p>Thanks</p>
