title: tools:replace specified at line:19 for attribute android:appComponentFactory, but no new value specified app main manifest
body: <p>I am trying to compile a 6 months old code, but I get this error:</p>
  
  <p><code>tools:replace specified at line:19 for attribute android:appComponentFactory, but no new value specified app main manifest (this file), line 18 Error: Validation failed, exiting app main manifest (this file)</code></p>
  
  <p>To fix this issue, I added the following line in my <code>AndroidManifest.xml</code></p>
  
  <pre><code>tools:replace="android:appComponentFactory"
  </code></pre>
  
  <p>But now I got this error:</p>
  
  <p><code>Manifest merger failed with multiple errors, see logs</code></p>
  
  <p>When I googles this error, it asks me to remove that line from <code>AndroidManifest.xml</code> that I added in first step. So, it's kind of a loop. How can I get rid of this.</p>
