title: Build android error at stage app:mergeDebugResources, ParseError AttributeNSNotUnique
body: <p>I've been trying to build my Android Application on Android Studio 4.2 with Gradle 4.2.1, but I am faced with the following error of which I was only able to find <a href="https://stackoverflow.com/questions/66780877/parseerror-at-row-col66-34-message-xml-names-19990114attributensnotuniqu">one question one month ago</a>, and another one from <a href="https://stackoverflow.com/questions/68177399/execution-failed-for-task-appmergedebugresources-parseerror">today</a> which was not solved neither.</p>
  <pre><code>FAILURE: Build failed with an exception.
  
  * What went wrong:
  Execution failed for task ':app:mergeDebugResources'.
  &gt; A failure occurred while executing com.android.build.gradle.internal.res.ResourceCompilerRunnable
     &gt; Resource compilation failed. Check logs for details.
  
  * Try:
  Run with --debug option to get more log output. Run with --scan to get full insights.

  <p><strong>Edited</strong>: This is my merged AndroidManifest.xml file, it looks like this without dependencies, still the message error remains the same and in the same line [22,347]:</p>
  <p><a href="https://i.stack.imgur.com/uIna5.png" rel="noreferrer"><img src="https://i.stack.imgur.com/uIna5.png" alt="Android Manifest Without Dependencies" /></a></p>
  <p>I have also taken a look at all my *.xml files, from layouts to values, and android studio has validated them, so I don't understand the exception.</p>
  <p>The part related to the Parse Error:</p>
  <p>Message: <a href="http://www.w3.org/TR/1999/REC-xml-names-19990114#AttributeNSNotUnique?androidx.constraintlayout.widget.ConstraintLayout&amp;layout_width&amp;http://schemas.android.com/apk/res/android" rel="noreferrer">http://www.w3.org/TR/1999/REC-xml-names-19990114#AttributeNSNotUnique?androidx.constraintlayout.widget.ConstraintLayout&amp;layout_width&amp;http://schemas.android.com/apk/res/android</a></p>
  <p>Makes me think there is something wrong with my layouts, but the IDE says they are fine and render normally.</p>
  <p>Dependencies on the build.gradle (previous image shows the manifest after they were commented out):</p>
