Develop an application for Android that captures network packets from other applications running on same phone using VPN service in Android. The captured packet need to be saved in the device itself.

I am looking for an experienced freelancer to help me develop an application for Android that can capture network packets from other applications running on the same phone via VPN. The captured packet needs to be stored locally in the device itself for security monitoring purposes. We have no preference as to which programming language should be used for this project. As far as the design of the user interface, I am open to the developer's ideas and suggestions, so long as it remains user-friendly. If you think you have the necessary skills and experience for this project, please reach out and we can discuss further details. Thank you!
