It's possible to use third-party dat files in the same folder, like h2y. Android projects under V2rayNG folder can be compiled directly in Android Studio or using Gradle wrapper. But the v2ray core inside the aar is (probably) outdated. The aar can be compiled from the Golang project under AndroidLibV2rayLite folder. v2rayNG can run on Android Emulators. But VPN mode will not work if the system doesn't support it. -

Kitsunebi
A fully-featured V2Ray client for Android
A fully-featured V2Ray client for Android. The Core used by Kitsunebi extends the function of v2ray-core, and adds a strategy of selecting the fastest node according to the node delay value. You can add a node group on the graphical interface to enable it. If you use custom configuration, there are several configuration items, except for tolerance. The delay test is not ICMP Ping or TCP Ping, the method used is roughly the same as that used by the latency strategy in load balancing, actually sends a proxy request to outbound, and records the time it takes to return non-null data. The delay test is also equivalent to the availability or connectivity test. As long as the delay can be measured, it means that the node is available. If it cannot be measured or times out, the availability is unknown. -

SimpleX
The first messaging platform operating without user identifiers
Other apps have user IDs: Signal, Matrix, Session, Briar, Jami, Cwtch, etc. SimpleX does not, not even random numbers. This radically improves your privacy. The video shows how you connect to your friend via their 1-time QR-code, in person or via a video link. You can also connect by sharing an invitation link. Temporary anonymous pairwise identifiers SimpleX uses temporary anonymous pairwise addresses and credentials for each user contact or group member. It allows to deliver messages without user profile identifiers, providing better meta-data privacy than alternatives. Many communication platforms are vulnerable to MITM attacks by servers or network providers. To prevent it SimpleX apps pass one-time keys out-of-band when you share an address as a link or a QR code. Double-ratchet protocol. OTR messaging with perfect forward secrecy and break-in recovery. NaCL cryptobox in each queue to prevent traffic correlation between message queues if TLS is compromised. -
