Android Studio中Manifest文件无语法错误却触发ParseError问题求助

Hey there! Let's break down this error you're facing. First off, the error message mentions a duplicate layout_width attribute on a RelativeLayout, but looking at the Manifest file you shared—there's no RelativeLayout anywhere in it! That's a big hint about where the actual problem lies.

Here's what to do next: #

• Check your layout XML files, not the Manifest: This error almost certainly comes from one of your activity/fragment layout files (like activity_splash.xml, activity_menu.xml, etc.), not the Manifest. Android Studio can sometimes mislabel the source of XML parsing errors, so head to your res/layout folder first.
• Look for duplicate attributes in RelativeLayout: Open each layout file and find any <RelativeLayout> tags. Check if you've accidentally added the android:layout_width attribute twice, like this:

  <RelativeLayout
      android:layout_width="match_parent"
      android:layout_width="wrap_content" <!-- Duplicate line here! -->
      android:layout_height="match_parent">
  

  Delete one of the duplicate layout_width lines, and that should fix the parsing error.
• Double-check the Manifest (just in case): If you're still stuck, verify your Manifest file for hidden issues:
  • Look at line 12 (where the error is flagged) and surrounding lines for special characters or redundant code that might have snuck in during copy-pasting.
  • Ensure none of your <application> or <activity> tags have duplicate attributes (e.g., two android:label entries on the same element).

Quick recap #

The error message's mention of RelativeLayout gives it away—this is a layout file issue, not a Manifest problem. Fixing the duplicate attribute in your layout XML should resolve the ParseError right away.
