Re: ebook-reader permissions - no explanation given

If I remember correctly, there is/was an oddity about permissions and
their their grouping, if an app asks you to grant one permission from a
particular group, it can later "grant itself" additional permissions
from that same group, without you having to agree...

Personally, I admit I never understood how Android does permissions.

To see how other similar apps handled permissions, I arbitrarily installed
 *Cool Reader* by Vadim Lopatin with In-app purchases
 free,adfree,gsf_req,rated 3.9 star, 265K reviews, 10M+ Downloads
 <https://play.google.com/store/apps/details?id=org.coolreader>

Unlike com.github.axet.bookreader Book Reader, Cool Reader asked for
permissions as it required them (i.e., when I opened an epub using it).

In the Muntashirakon "Uses Permissions" tab, it looks very different.
<https://github.com/MuntashirAkon/AppManager>

Cool Reader:
 android.permission.BLUETOOTH
 android.permission.BLUETOOTH_ADVERTISE
 android.permission.BLUETOOTH_CONNECT
 android.permission.BLUETOOTH_SCAN
 android.permission.FOREGROUND_SERVICE
 android.permission.INTERNET
 android.permission.POST_NOTIFICATIONS
 android.permission.READ_EXTERNAL_STORAGE
 android.permission.READ_MEDIA_AUDIO
 android.permission.READ_MEDIA_IMAGES
 android.permission.READ_MEDIA_VIDEO
 android.permission.READ_PHONE_STATE
 android.permission.WAKE_LOCK
 android.permission.WRITE_EXTERNAL_STORAGE
 com.android.vending.BILLING

Yet, in the Muntashirakon "Permissions" tab, there's only one item.
 com.google.android.gms.auth.api.signin.permission.REVOCATION_NOTIFICATION
 
Note that I have com.android.vending.BILLING disabled, so my phone
is incapable of processing billing (which turns out to be a nice way
to legitimately get payware apps for free, I found out accidentally).
