title: Can't run react native expo project on android emulator
body: <p>After <code>npm start</code> everything works fine. Now I am trying to open the emulator by pressing <code>a</code> and that error shows:
  <code>Couldn't start project on Android:</code>. 
  This is my <code>~/.bashrc</code> file ( using Ubuntu )</p>
  
  <pre><code>export ANDOIRD_SDK=/home/toma/Android/Sdk
  export ANDROID_HOME=$HOME/Android/Sdk
  export PATH=$PATH:$ANDROID_HOME/emulator
  export PATH=$PATH:$ANDROID_HOME/tools
  export PATH=$PATH:$ANDROID_HOME/tools/bin
  export PATH=$PATH:$ANDROID_HOME/platform-tools
  </code></pre>
  
  <p>I have this emulator opened from android studio.
