title: what data is sent or received from apps installed on my android?
body: <p>I am trying to build an android application which will display the user what data was sent from all apps and what data was received on all apps installed on the device.</p>
  
  <p>I have searched but nothing came which could give me a start. Is there any encryption/decryption techniques used(Since i have no idea about the same).</p>
  
  <p>It would be a privilege if i get to know where to start with this project.</p>
