title: Android: log.d doesn't work while log.i does
body: <p>i have the following issue programming an android application with android studio. When I use <code>Log.d(...)</code> in the code, no logging output is generated while all other logging functions, e.g. <code>Log.i(...)</code>, work in exactly the same position.</p>
  
  <p>Example that does not work:</p>
  
  <pre><code> @Override
   protected void onStart() {
      super.onStart();
      Log.d("MainActivity", "onStart called.");
   }
  </code></pre>
  
  <p>But this works:</p>
  
  <pre><code>@Override
  protected void onStart() {
      super.onStart();
      Log.i("MainActivity", "onStart called.");
  }
  </code></pre>
  
  <p>The Logcat level is set to Debug, the correct device and application are chosen, and as filter I use the Tag "MainActivity". I have already tried to restart logcat, clear the log, nothing successful. </p>
  
  <p>I have also that the logging level with <code>adb shell setprop log.tag.MainActivity DEBUG</code> so that <code>Log.isLoggable("MainActivity", Log.DEBUG)</code> returns true.</p>
  
  <p>The App is also set to debuggable.</p>
  
  <p>I am very thankful for any hint.</p>
  
  <p>EDIT:
  I seems to be an issue with my phone (Honor8). Although it hasn't worked in the emulator as well, executing <code>adb shell setprop log.tag.MainActivity DEBUG</code> fixes the problem at least in the emulator. </p>
