title: With Scoped Storage introduced in Android Q, how am I supposed to develop a file manager app?
body: <p>Android Q will introduce a new sandboxed filesystem for apps, Scoped Storage. This policy will be enforced on any apps targeting API>=29. How should a thrid-party file manager app get through this restriction and continue to work properly?</p>
  
  <p>This question is meant to be generic for any apps that have some file-managing functionalities, like browsing, saving, loading, syncing, etc.</p>
