title: Problems with adb.exe - AdbHostServer.cpp:93: Unable to connect to adb daemon on port: 5037
body: <p>I have a problem with adb.exe of Android Studio 3.4.</p>
  
  <p>When I run the emulator, I get this error:</p>
  
  <blockquote>
    <p>Emulator: emulator: ERROR: AdbHostServer.cpp:93: Unable to connect to adb
        daemon on port: 5037</p>
  </blockquote>
  
  <p>I opened a terminal with the rute of the adb.exe: <code>C:\Users\Christian\AppData\Local\Android\Sdk\platform-tools</code></p>
  
  <p>And here I tried with adb kill-server and then adb start-server and I get this:</p>
  
  <pre><code>*daemon not running; starting now at tcp:5037
  *daemon started successfully
  </code></pre>
  
  <p>When i run again the same error appears, i get this in terminal with the command adb devices:</p>
  
  <pre><code>List of devices attached
  emulator-5554   offline
  </code></pre>
  
  <p>I emulate Nexus 5X API 28 with System Image: Pie 28 x86 Android 9.0.</p>
  
  <p>I download the <a href="https://androidstudio.io/downloads/tools/download-the-latest-version-of-adb.exe.html" rel="noreferrer">last version</a> of abd.exe in for Windows</p>
  
  <p>I also reinstalled the Android Studio and the emulator, but the error still appears.</p>
  
  <p>How can I solve that?</p>
