Complete Java code and XML code for making VPN Android studio

 To implement a virtual private network (VPN) in your Android app, you can use the Android VPN Service API. Here's an example of how to set up a simple VPN service in your Android app:

1. Create a new Android Studio project and add the following to your AndroidManifest.xml file:

<uses-permission android:name="android.permission.INTERNET" />

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

<uses-permission android:name="android.permission.WAKE_LOCK" />

<uses-permission android:name="android.permission.CONFIGURE_VPN" />

<uses-permission android:name="android.permission.PREPARE_VPN" />

<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />

<uses-feature android:name="android.hardware.wifi" />

<uses-feature android:name="android.software.connectionservice" />

2. Create a new class that extends VpnService and overrides the onStartCommand method. This is where you will set up your VPN connection:

public class MyVpnService extends VpnService { @Override public int onStartCommand(Intent intent, int flags, int startId) { // Set up your VPN connection here return START_STICKY; } }

3. To set up the VPN connection, you will need to create a VpnService.Builder and configure it with the appropriate parameters. For example:

VpnService.Builder builder = new VpnService.Builder(); builder.addAddress("10.0.2.15", 24); builder.addRoute("0.0.0.0", 0); builder.addDnsServer("8.8.8.8"); ParcelFileDescriptor vpnInterface = builder.setSession("My VPN") .setConfigureIntent(pendingIntent) .establish();

4. To start the VPN connection, call start on the VpnService.Builder object:

vpnInterface.start();

5. To stop the VPN connection, call close on the ParcelFileDescriptor object:
6. 
   

vpnInterface.close();
