title: Gradle Project Sync Failed after updating to Android Studio 3.3.0
body: <p>I haven't touched my Android Studio for a loooong time, it still worked fine when I launched it, but then I updated to 3.3.0 and I get a 'gradle project sync failed'. I know this is not trivial to debug via SO, but I tried to find anything similar and I lack of knowledge about the entire studio didn't help.</p>
  
  <p>So maybe you can guide me to a solution, I'm not sure what files are necessary, but here is the actual error:</p>
  
  <blockquote>
    <p>ERROR: Failed to parse XML in C:\Users\roberts\AndroidProjects\LingoFlash\app\src\main\AndroidManifest.xml
    ParseError at [row,col]:[27,9]
    Message: expected start or end tag
    Affected Modules: app</p>
  </blockquote>
  
  <p>This is the AndroidManifest.xml file:</p>
  
  <pre><code> 20     &lt;application
   21         android:allowBackup="true"
   22         android:icon="@mipmap/ic_launcher"
   23         android:label="@string/app_name"
   24         android:supportsRtl="true"
   25         android:theme="@style/MyMaterialTheme"&gt;
   26         //------------------------------------------------------------------------------------------
   27         &lt;activity android:name=".MainActivity"&gt;
   28             &lt;intent-filter&gt;
   29                 &lt;action android:name="android.intent.action.MAIN" /&gt;
   30                 &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
   31             &lt;/intent-filter&gt;
   32         &lt;/activity&gt;
  </code></pre>
  
  <p>so what's wrong at line 27? seems to point to the MainActivity</p>
  
  <p>before I paste a ton of data, what would help to debug this?</p>
