Does Android automatically delete obb expansion files after install?

I have an obb file which is a zip file, which I unpack after downloading it in the obb folder. Then I copy the unpacked obb files to Internal Storage.

I just released an app to Internal testing. I installed the app, but I was hoping that the obb files would be automatically deleted, but it seems they are still hanging in there, and when I check the Storage size in Settings, the size of the apk file includes the data in the obb folder. I don't want this, because my app is taking less storage then it's actually showing in Settings / Storage.

Is there an Android process that automatic removes the obb files later on, or do I need to delete them myself when I don't need them anymore, right after copying them to internal storage?

The answer is no. The only time the OBB file gets deleted is when the user uninstalls the app. Or when the app deletes the file itself.

On a side note, which I happened to find out only later, if you delete or rename your OBB file, it gets re-downloaded every time you release an app update. So you are better off using the OBB file as is and leave it there as originally installed, and using a second OBB file for updates (your listed app size will include the OBB file though), or another option is using a file hosting service such as Dropbox if you don't want the OBB file just sitting there.
