title: How to know what data an Android app is sending out
body: <p>How would you find out what kind of information an Android app is sending back to the "mothership"? For example, if an app is sending your ID, gender, etc. to advertisers.</p>
  
  <p>Is there a way to do this in an Android app? Or would it have to be done via a packet sniffer over Wi-Fi?</p>
