title: Buildozer packs an .apk, but it doesn't run
body: <p>I'm using Ubuntu 64 14.04 on VirtualBox, I've successfully made .apk-file using Buildozer, but when I start it on Android SDK emulator (running on Windows), it shows black screen with title at the top for a few seconds and then quits. (By the way, what emulator is better? This one is too slow.) How can I watch the cause of it?</p>
  
  <p><strong>UPDATE:</strong></p>
  
  <p>When I run <code>buildozer android run</code> on Ubuntu, it says:</p>
  
  <pre><code># Application pushed.
  # Application started.
  </code></pre>
  
  <p>And nothing happens. I haven't Android device and I don't know, should emulator run in this case. I'm running emulator separately on Windows, so I can't understand how to use logcat here.</p>
  
  <p><strong>UPDATE:</strong></p>
  
  <p>This is a part of log when I run my app.</p>
