title: No debuggable processes in logcat when phone detected by Android studio
body: <p>Everyone!</p>
  <p>I got so confused by android studio.
  when I plug in my phone to debug apps, logcat can detect my phone, but I can not choose process. It said &quot;no debuggable processes&quot;,not common &quot;no debuggable applications&quot;.</p>
  <p>My phone is samsung s5 (android 6.0),rooted.</p>
  <p>Any ideas?</p>
  <p>Thanks!</p>
