title: Xamarin.Android, AndroidManifest.xml, AndroidManifestMerger, xmlns:tools schema, replace always manually
body: <p>When compile my Xamarin Forms Android application, visual studio, show me an error's list of AndroidManifest.xml conflict, for example:</p>
  <pre><code>/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets(3,3): Error AMM0000:  is also present at AndroidManifest.xml:14:9-41 value=(@string/app_name). (AMM0000)
  
  /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets(3,3): Error AMM0000:  Suggestion: add 'tools:replace=&quot;android:label&quot;' to &lt;application&gt; element at AndroidManifest.xml:19:3-79:17 to override. (AMM0000)
  </code></pre>
  <p>So i open AndroidManifest.xml from debug folder, replace with tools:replace into application tag, add tools schema into manifest tag, save it, recompile my application and it run without error.</p>
  <p><strong>But WHENEVER i compile my Xamarin Forms Android application, must follow previous steps MANUALLY</strong>.</p>
  <p>I also add <code>&lt;AndroidManifestMerger&gt;manifestmerger.jar&lt;/AndroidManifestMerger&gt;</code>, into my Android .csproj</p>
  <p>This issue is showed into DEBUG and RELEASE mode!!</p>
