title: "No devices available" in Visual Studio 2015
body: <p>I trying to deploy Native activity application(Android, C++) on the Visual Studio 2015 embedded emulator. But have a problem: start debugging button has label &quot;no devices available&quot;:<a href="https://i.stack.imgur.com/X7A3G.png" rel="noreferrer"><img src="https://i.stack.imgur.com/X7A3G.png" alt="enter image description here" /></a></p>
  <p>But my AVD manager has some devices.</p>
  <p>Deploy output:</p>
  <blockquote>
  <p>Deploy started: Project: Android3.Packaging, Configuration: Debug x86 ------</p>
  <p>Error installing the package. The package 'C:\Users\User\Documents\Visual Studio 2015\Projects\Project\Android3\x86\Debug\Android3.apk' does not exist on disk.</p>
  <p>Invalid package information.</p>
  </blockquote>
  <p>I already had the same problem and tried to reinstall Visual Studio several times but it's gives nothing. Besides this in the last time I had to clean the registry manually due to Visual Studio 2015 installer said that I already had android-sdk on the my computer but this was not so.</p>
  <p>How can I fix it? How can I completely uninstall Visual Studio and install it right?</p>
  <p>OS: Windows 7</p>
  <p><strong>UPD:</strong></p>
  <p>If I set &quot;Android3.NativeActivity&quot; as startup project, then I get error window:</p>
  <blockquote>
  <p>Unable to start debugging. Check your debugger settings by opening
  project properties and navigation to 'Configuration properties --&gt;
  Debugging'</p>
  </blockquote>
  <p>If I set &quot;Android3.Packaging&quot; as startup project, then I get:</p>
  <blockquote>
  <p>Error installing the package. The device '' is invalid or not running.  Please switch to another device, or use the Android Virtual
  Device (AVD) Manager to start a compatible emulator, or connect a
  compatible Android device.</p>
  <p>The device is invalid or is not running.</p>

  <p>in the deploy output.</p>
  <p>My AVD manager looks like:
  <a href="https://i.stack.imgur.com/9K7Bs.png" rel="noreferrer"><img src="https://i.stack.imgur.com/9K7Bs.png" alt="enter image description here" /></a></p>
  <p>AVD manager has emulators for API level 19.</p>
  <p>Android3.NativeActivity-&gt;Properties-&gt;General-&gt;Target API Level = KitKat 4.4 - 4.4.4, (android-19)</p>
  <p>Android3.Packaging-&gt;Properties-&gt;General-&gt;Target API Level = KitKat 4.4 - 4.4.4, (android-19)</p>
  <p>So everything set as API level 19.</p>
  <p>What else could be wrong?</p>
