title: File with com.android.support.constraint:constraint-layout:1.0.0-alpha2
body: <p>I am not very familiar with Android but a friend of my friend said he made an app for my website on his computer. So he sent me the source file and I tried to rebuild the application but it doesn't work. I even tried to create a new project on my computer and copy/paste the code of each page. Then just change the project name but the problem is the same as below and I cant contact him again as he had done it just as a service for me. So I hope someone here can help me with this case because I have really become so tired of trying fix this issue.</p>
  
  <p>Error message is:</p>
