title: in Android 10, how to tracking an application's network statistics (netstats) using ADB
body: <p>I use "adb shell cat /proc/net/xt_qtaguid/stats" to get my application's network statistics.</p>
  
  <p>But it doesn't work in Android 10(Android Q), I got a <code>Permission denied</code>:</p>
  
  <pre><code>cat: /proc/net/xt_qtaguid/stats: Permission denied
  </code></pre>
