title: Google Maps - A required meta-data tag in your app's AndroidManifest.xml does not exist
body: <p>I want to implement Google Map in my Android app, I just follow the Google Maps Platform instruction, but it didn't work. I don't know why meta-data does not exist while I already declare it in the manifest:</p>
  <p>AndroidManifest.xml</p>
  <pre><code>&lt;application
          android:allowBackup=&quot;true&quot;
          android:icon=&quot;@mipmap/ic_launcher&quot;
          android:label=&quot;@string/app_name&quot;
          android:roundIcon=&quot;@mipmap/ic_launcher_round&quot;
          android:supportsRtl=&quot;true&quot;
          android:usesCleartextTraffic=&quot;true&quot;
          tools:ignore=&quot;AllowBackup&quot;
          tools:targetApi=&quot;m&quot;&gt;
  
          &lt;activity android:name=&quot;some.Activity&quot;&gt;&lt;/activity&gt;
  
  
          &lt;meta-data
              tools:replace=&quot;android:value&quot;
              android:name=&quot;com.google.android.gms.version&quot;
              android:value=&quot;${MAPS_API_KEY}&quot; /&gt;
  &lt;/application&gt;
