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 But the v2ray core inside the aar is (probably) outdated.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

    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.
