Android /data/app directory

[hydroperx]

Let's say some app com.qux.bar has some assets (app's installation files) like {project}/scenes/waterfall.webp (not statically incorporated through include_bytes! in Rust).

According to AI information, these files reside in /data/app/{...}, and not /data/data/{ID}. I've downloaded ZArchiver in my Android phone (not rooted) to see what's in /data/app/{...}, but it turns out it's structured like

• data/
  • app/
    • ~~-ZDrxMxFFkgo...bg==/
      • com.instagram.android-QD9SphAoXwr...Hg==/
        • lib/
        • oat/
        • base.apk
        • ...
    • ...

I'm not sure if this is what is considered an "installation directory" (in Windows it's generally the place where executable resides plus files that aren't fixed in the RAM like heavy icon assets, object descriptions and scenes).

I know that Adobe AIR has the concept of app:// URLs, which are relative to the app's "installation directory". I wanted to produce the same in Rust, but am a bit confused about the Android case.

We have at least android_activity::AndroidApp::internal_data_path(), but it probably yields something like /data/data/{ID}, and as I've shown, data/app/... entries seem to have a base64 encoding inside them.
