Snapcraft files for v2rayA
To build the snap yourself, just run the command below. Replace 1.5.8.1 by the version you need.
./snap.sh 1.5.8.1
To install the freshly-built snap, run
snap install --dangerous --jailmode ./v2raya_1.5.8.1_amd64.snap
(omit the --jailmode flag on non-Ubuntu systems)
Then give it all the required permissions, and start:
snap connect v2raya:firewall-control
snap connect v2raya:network-control
snap start v2raya
The aformentioned actions are only required when installing from a .snap file for development/testing purposes. The end user wishing to install v2rayA from snapcraft.io doesn't have to paste all these commands. A simple snap install v2raya is sufficient to install the snap from snapcraft.
