title: Couldn't open uiautomatorviewer after setting PATH
body: <p>Today I followed the Youtube for setting my laptop(linux-Debian) to install
  the android SDK tool , I have set PATH in environment variables via command line
  [terminal line]：</p>
  
  <pre><code>hauying@hauying-yoga-linux:~$ echo $PATH
  /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/home/hauying/Android/tools:/home/hauying/Android/platform-tools
  </code></pre>
  
  <p>After setting the PATH successfully, I can't open "uiautomatorviewer".
  It shows following error when I try to open it:
  [terminal line]：</p>
  
  <pre><code>hauying@hauying-yoga-linux:~/Andriod/tools/bin$ '/home/hauying/Andriod/tools/bin/uiautomatorviewer' 
  -Djava.ext.dirs=/home/hauying/Andriod/tools/lib/x86_64:/home/hauying/Andriod/tools/lib is not supported.  Use -classpath instead.
  Error: Could not create the Java Virtual Machine.
  Error: A fatal exception has occurred. Program will exit.
  </code></pre>
  
  <p>I tried using command -classpath ,but it can't find this command.</p>
  
  <p>How can I open my "uiautomatorviewer". Please help.</p>
