title: App hang on install in Android Studio
body: <p>Usually I build an app in <code>Android Studio</code> to test an app on Phone. But this occurs when I just click the <code>Run app</code></p>
  
  <pre><code>Waiting for device.
  Target device: motorola-nexus_6-ZX1G227B86
  Uploading file
      local path: F:\HeadFirstAndroid\MateClient\app\build\outputs\apk\app-debug.apk
      remote path: /data/local/tmp/com.diyu.org.mateclient
  Installing com.diyu.org.mateclient
  DEVICE SHELL COMMAND: pm install -r "/data/local/tmp/com.diyu.org.mateclient"
  </code></pre>
  
  <p>It seems that the process is stuck on the <code>pm install</code> and no app is installed on my phone. What's the issue?</p>
  
  <p>And other projects acts the same, hang on the install.</p>
