How to use wireguard tunnel library?

I want to create a third-party VPN app by using the library com.wireguard.android:tunnel (1.0.20211029) Can anyone help me to provide me any good resources or guide me?

In my app I am importing .config file from file manager now how to connect that file to server using tunnel library . I am using java .

I did followed https://github.com/WireGuard/wireguard-android but The app wraps a lot of the tunnel library code. I am looking for a simple example of how to use the tunnel library directly without all the wrapping with TunnelManager and ObservableTunnel.

Please guide me

in my case the dns address needed to be added and I added it to anton2319's code and the vpn worked. Like this. Thank you anton2319.

backend.setState(tunnel, UP, new Config.Builder()
                  .setInterface(interfaceBuilder.addDnsServer(InetAddress.getByName("your dns adress")).addAddress(InetNetwork.parse("10.0.0.2/32")).parsePrivateKey("privatekeybase64").build())

UPD: added request intent, because it is necessary on first connection

UPD 2: I have a made a step-by-step guide: https://github.com/Anton2319/Anton2319/blob/master/articles/wireguard-guide/article.md

I think this code will work for you:

In your main activity, use this (replace IP, pubkey and privatekey):

Tunnel tunnel = new WgTunnel();
Intent intentPrepare = GoBackend.VpnService.prepare(this);
if(intentPrepare != null) {
    startActivityForResult(intentPrepare, 0);
}
Interface.Builder interfaceBuilder = new Interface.Builder();
Peer.Builder peerBuilder = new Peer.Builder();
Backend backend = new GoBackend(this);

AsyncTask.execute(new Runnable() {
    @Override
    public void run() {
        try {
            backend.setState(tunnel, UP, new Config.Builder()
                      .setInterface(interfaceBuilder.addAddress(InetNetwork.parse("10.0.0.2/32")).parsePrivateKey("privatekeybase64").build())
                        .addPeer(peerBuilder.addAllowedIp(InetNetwork.parse("0.0.0.0/0")).setEndpoint(InetEndpoint.parse("yourhost:51820")).parsePublicKey("pubkeybase64").build())
                        .build());

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
});

In the same package as your main activity, create this class:

package package.name.here;

import com.wireguard.android.backend.Tunnel;

public class WgTunnel implements Tunnel {
    @Override
    public String getName() {
        return "wgpreconf";
    }

    @Override
    public void onStateChange(State newState) {
    }
}

In AndroidManifest.xml:

<application ...>
    <service android:name="com.wireguard.android.backend.GoBackend$VpnService" android:permission="android.permission.BIND_VPN_SERVICE" android:exported="true">
                <intent-filter>
                    <action android:name="android.net.VpnService"/>
                </intent-filter>
    </service>
</application>
<uses-permission android:name="android.permission.INTERNET" />
