title: PWA inside a APK: why is it isolated from Android APIs?
body: <p>When you put a Progressive Web App inside an APK, to sell on Goolge Play, for example by the use of Bubblewrap and Trusted Web Activity, the PWA can not interact with the Android APIs. Correct? If I have misunderstood this, please correct me and point me towards documentation.</p>
  <p>So even though it is an APK, and it comes from a trusted source like Google Play, the code it runs (Javascript) will not be allowed to do the same things a normal Android app can do. What is the rationale behind that? Google has a mission to make PWAs just as capable as native apps, so it makes no sense to me.</p>
  <p>For example, I need access to the file system from my PWA. I mean real access, not a neutered access like with the upcoming Native File System API. The user accepts file access at installation, and then my app can do whatever it wants. So I thought I'd just use the Android APIs to get access, but they are off limits. How have you solved this issue in your own PWAs?</p>
