title: How to get the captured / saved image from camera to another app?
body: <p>I have a camera app that allows the user to "Save" or "Discard" image after each photo is taken. If "Save" is clicked the app goes back to the <code>MainActivity</code> (camera preview) and keeps the photo. If "Discard" is clicked the photo is removed and goes back to the <code>MainActivity</code> (camera preview). This all works fine.</p>
  
  <p>I have a standard email app (TypeApp) that allows users to attach a photo by "Take a Picture" function which when clicked shows all installed camera. I want to use my camera app to allow this but when I save the photo and click "Back" no image is attached. I've seen it worked on other camera app but I don't know how to begin to implement this feature in my app.</p>
  
  <p>How do I get my camera app to send back the location of the image to the standard email app when the user clicks the "Save" button.</p>
  
  <p>Any guidance would be appreciated.</p>
