title: How to show Android Studio's Messages Window?
body: <p>When I build a project and there are errors, the Messages window that shows all the errors does not always show. I have to build the project (i.e. <kbd>Ctrl</kbd> + <kbd>F9</kbd> ) twice or more in order to see the window.</p>
  
  <p>When the window is not shown, View > Tool > Messages Alt + 0 is grayed out as shown by the following screenshot.  How can I show the window when there are build errors?</p>
  
  <p>I am running the latest Android Studio on Windows 8.</p>

  <p>Android Studio 3.1 seems to have this window removed, many people may come here because of missing the Messages Window due to a different reason, and yuval's answer may be the right one in this case.</p>
