A simple Java module with sample source code to implement the v2ray on Android.
This module is built from a custom library based on the xray core . With this module, you can easily develop your VPN application based on powerful v2ray protocols. This module currently supports v2ray short links (URI) thanks to a custom library (may have bugs).
In fact, this module provides you a v2ray client with xray core, which you can manage with static functions in V2rayController .

Sample Application You can download sample release of this module from Github Releases of this repo

Before anything, make sure you are using the latest version of Android Studio. The sample project does not use any special dependencies or tools, so if there are no network or software issues on your system, you can simply clone it and build it in Android Studio with one click.

• First, check that the version of gradle and build config of your project is compatible with the version used in this source.
• Clone or download this repo.
• Open your project in android studio and navigate to File -> New -> Import module. Then select the source directory to v2ray from the cloned repository.
• After Gradle build , Open setting.gradle file in your project and add this to your Gradle repositories block.

flatDir {
        dirs 'v2ray/libs'
}

• Add module as a dependency to your main project by adding this line to app-level build.gradle.

implementation project(path: ':v2ray')

• Click on Rebuild project from Build Tab .

Note : The contents of the manifest of your main project will be automatically merged with the contents of the library monifest, so there is no need to manually copy the contents.

• First, the library needs to be initialized. So call this function for this purpose in the primary methods of your activity.

V2rayController.init(this, R.drawable.ic_launcher, "V2ray Android");

R.drawable.ic_launcher is a drawable resource that will be used in vpn notification. "V2ray Android" is application name

• You can get the version of core with this

V2rayController.getCoreVersion()

• With this function you will get current status of module

V2rayController.getConnectionState()

This will return an enum with three state : CONNECTED,CONNECTING,DISCONNECTED

• For **start a connection **

V2rayController.startV2ray(this, "Test Server", "vless:\\test@test", null);

"Test Server" will be used as remark in notification. "vless:\\test@test" is a string of your config (could be uri or full json) null means no application package will be bypass the tunnel

• For stop connection

V2rayController.stopV2ray(this);

you should call this function in main thread.
