title: Can't determine type for tag '<meta-data android:name="com.google.android.geo.API_KEY"
body: <p>I'm working on a small Android app which involves Google Maps (created with Android Studio by selecting the Google Maps activity template).</p>
  
  <p>It works fine on my test phone, but when I build a signed APK and install it on another phone, the map is blank.</p>
  
  <p>After some Googling, perhaps the cause of the problem is because I'm using the wrong key.</p>
  
  <p>I have this line in google_maps_api.xml:</p>
  
  <pre><code>&lt;string name="google_maps_key" translatable="false" templateMergeStrategy="preserve"&gt;AIzaxxxxxxxxxxxxxxxxxx&lt;/string&gt;
  </code></pre>
  
  <p>Change that into:</p>
  
  <pre><code>&lt;meta-data android:name="com.google.android.geo.API_KEY" android:value="AIzaxxxxxxxxxxxxxxxxxx" /&gt;
  </code></pre>
  
  <p>Android Studio complains:
  Error: Can't determine type for tag ''

  <p>Pardon the screenshot. For unknown reasons, the whole error message cannot be displayed properly on SO. How to solve this?</p>
