  Error: Could not find apk architecture: arm build-type: debug
  [ERROR] An error occurred while running subprocess cordova.
  
      cordova run android exited with exit code 1.
  
      Re-running this command with the --verbose flag may provide more information.
  </code></pre>
  
  <p>Under the directory <code>platforms/android/build/outputs/apk</code>, there is only one folder called debug under which there are two file <code>android-debug.apk</code> and <code>output.json</code>. </p>
  
  <pre><code> apk
    |---debug
          |---android-debug.apk
          |---output.json
  </code></pre>
  
  <p>I suspect there should be some arm architecture file in apk directory, but I don't know how to generate it.</p>
  
  <p>Can you help me to solve this run android error?</p>
