Our application uses the VpnService component on Android to provide users with a scientific Internet solution, especially for users in China. In China, due to network blocking and censorship, many international Internet services, such as Google and some social media sites, may be restricted or inaccessible. To solve this problem, we developed a network proxy function based on VpnService to ensure that users can access blocked content safely and privately.The following are the key features of our application using VpnService:1. Bypass network blockade: Our application uses VpnService to create a VPN connection to bypass Chinas network blockade through servers located in other countries or regions. This allows users to access blocked websites and services, including Google, social media, news sites, and more.2. Privacy and Security: VpnService also provides encryption of users’ Internet connections, ensuring that users’ data is protected during transmission. This helps prevent prying eyes and ensures user privacy.3. Customize VPN connections: We allow users to select server locations and protocols so they can customize their VPN connections to meet specific needs, provide faster connections or access content in specific regions.By using VpnService, our application helps Chinese users easily bypass network blocks and surf the Internet scientifically while protecting their privacy and security. This provides users with wider internet access and provides them with a more open and free online experience. "
