Revise Android permissions

[rtaibah]

Canoe requests some permissions that it doesn't need. Mic, phone, USB....etc.

We need to justify these

Here we have good instructions for getting rid of mic at least: https://software.intel.com/en-us/forums/intel-xdk/topic/543472

Please do: Microphone and call information.

This seems like a bug, not an enhancement and is a deal breaker for some users to test/use

I'm actually using a docker image instead of mobile or linux native due to concerns with extra permissions for a third party app to manage my wallet

+1, wanted to try out nano along side btc lightning but I'm not giving this wallet permissions to:

• read phone status and identity
• record audio
• change audio settings

[gokr]

The audio stuff is due to us using an audio plugin to play sounds. Unfortunately the plugin can do much more, and yes, we should restrict it down. The phone status and identity... not sure, nothing we use at least.

[iljah]

What about using regular system notification sounds or something? I don't think that would require audio permissions.

I added this to next milestone, see if we can do something at least.
