Android VPN client developed using ics-openvpn library.

Build instructions:

• Download swig[https://www.swig.org/download.html] on the system.
• Add swig executable path to system/android studio environment path variables.
• Check if submodules in cpp folder are fetched on your system using git submodule command.
• Replace requestIdToken and google-services.json configuration according to firebase configurations on your account.
• If current ovpn servers are not working then replace .ovpn configurations. Some free sites to find ovpn configs: freeopenvpn, vpngate.

Tips to build imported openvpn module with latest code while integrating in a base app:

• Change plugin id("com.android.application") to id("com.android.library") in openvpn build.gradle.kts.
• set(SWIG_EXECUTABLE "swig.exe") set(SWIG_DIR "swigwin-4.1.1") Add above 2 lines to openvpn/src/main/cpp/CMakeLists.txt if not present.
• Enable multiDex on your base app.
• Enable databinding and add productFlavors['ui', 'skeleton' in build.gradle of base app.
• Comment out splits and applicantVariants register function in openvpn build.gradle.kts.
• Verify de.blinkt.openvpn.core.OpenVPNService service and de.blinkt.openvpn.activities.DisconnectVPN activity is added to base project's AndroidManifest file.

• Gradle version - 7.5, Gradle plugin version - 7.4.1
• SDK compile version - 33.0.0
