title: Save and read image but I can not find it when I open the folder
body: <p>I have a strange problem. I am developing an android app with Kotlin.</p>
  <p>My codes can generate and save the image <strong>myImg.png</strong> to the following directory</p>
  <p><strong>directory: &quot;/storage/emulated/0/Android/data/com.example.MyApp1/files/AutoDDD&quot;</strong></p>
  <p>and also it can read the same image from the same directory and show on imageView</p>
  <p>Also, the satement;</p>
  <pre><code>file.exists() 
  </code></pre>
  <p>returns true. However, the problem is that I can not see the image file when I open the folder AutoDDD on my laptop. I removed the application and re-installed, but the problem still occurs. I closed the editor and re-opened, re-run the app, but the problem still occurs.</p>
  <p>What is the reason?</p>
