v2rayNG
A V2Ray client for Android, support Xray core and v2fly core
A V2Ray client for Android supports Xray core and v2fly core. geoip.dat and geosite.dat files are in Android/data/com.v2ray.ang/files/assets (path may differ on some Android devices). Download feature will get an enhanced version in this repo (Note it need a working proxy). The latest official domain list and ip list can be imported manually. 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 But the v2ray core inside the aar is (probably) outdated.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. -

SagerNet
The universal proxy toolchain for Android
The universal proxy toolchain for Android, written in Kotlin. To use hysteria plugin with version smaller than 1.2.1, the highest compatible version of SagerNet is 0.8.1-rc02. The new protocol is designed to improve UDP performance and provide full replay protection. Using an MTU larger than the upstream interface will only improve speed in some scenarios and may result in UDP packet loss. According to the gfw.report et al's research, when connecting to the impacted VPSs, GFW is likely to block binary protocols unless it is an HTTP, TLS, or SSH connection, or the first 6 bytes of data sent from client to server can be interpreted as printable characters. This suggests in addition to TLS encryption, HTTP Header, this kind of censorship can also be temporarily evaded by only sending printable characters in the first 6 bytes of data. -

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. -
