title: Gallery strip like in telegram
body: <p>I would like to make image sharing easier by implementing what Telegram does to send a picture:</p>
  
  <p><a href="https://i.stack.imgur.com/gCR2e.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/gCR2e.png" alt="enter image description here"></a></p>
  
  <p>That is, a gallery strip with the latest pictures.</p>
  
  <p>But until now I've only worked with external intents to launch the native gallery.</p>
  
  <p>How can I implement this? Do I have to manually search the phone for pictures? I assume I require strong permissions for this?</p>
