Forked from : https://github.com/cosmojg/open-coinomi-android
And adapted for LightningCash Core.
Updated on August 31st 2022.
If you have the Google Play Store version or any older version, just copy the mnemonic phrase, uninstall, install this new version, paste the mnemonic code, and your old coins will still be there.
You will probably have to allow unknown apps to install this apk.
This app is safe to use, and stable.
Note for developers : the node linked to the electrumx server MUST have rpcserialversion=0 in the lightningcash.conf file !!!
