title: Android provider path for camera and security
body: <p>I followed <a href="https://inthecheesefactory.com/blog/how-to-share-access-to-file-with-fileprovider-on-android-nougat/en" rel="nofollow noreferrer">this article</a> to take picture in my application, however in the article the author gives the path <code>.</code> for the FileProvider.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;paths xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;external-path name="external_files" path="."/&gt;
  &lt;/paths&gt;
  </code></pre>
  
  <p>To what corresponds exactly <code>.</code> and can it be a security issue?</p>
