title: Android.mk *** missing separator. Stop. The LOCAL_SRC_FILES for a prebuilt library should only contain one item
body: <p>I cloned the following Telegram repo from Github:
  <a href="https://github.com/DrKLO/Telegram" rel="nofollow noreferrer">https://github.com/DrKLO/Telegram</a>
  I am using a PC not Apple.</p>
  
  <p>I opened the project in Android Studio. I then linked the project with the C++ files, which are included in the repo. I did this with ndkBuild and the Android.mk which is also included in the repo. </p>
  
  <p>When I try to build it in Android Studio using  gradle, I get the following error messages:</p>
  
  <p>In prebuilt-library.mk:</p>
  
  <pre><code>Error:(27, 0) *** missing separator.  Stop.
  </code></pre>
  
  <p>In Android.mk:</p>

  <p>I tried to remove tabs and added some, but I still can't make it work, so that the build is successful. 
  Maybe the problem is something else?
  Any Help is greatly appreciated as I've been trying to figure this out for 2 days now. </p>
