    <p>I've got exactly the same problem. The provided example</p> <pre><code>&lt;fragment xmlns:android="http://schemas.android.com/apk/res/android" xmlns:map="http://schemas.android.com/apk/res-auto" android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.SupportMapFragment" map:cameraBearing="112.5" map:cameraTargetLat="-33.796923" map:cameraTargetLng="150.922433" map:cameraTilt="30" map:cameraZoom="13" map:mapType="normal" map:uiCompass="false" map:uiRotateGestures="true" map:uiScrollGestures="false" map:uiTiltGestures="true" map:uiZoomControls="false" map:uiZoomGestures="true"/&gt; </code></pre> <p>works fine, but if you try to add it into a parent element it refuses to accept the xmlns. If you move the xmlns declaration to the top element it still refuses to accept the map prefix in the fragment:</p> <pre><code>Unexpected namespace prefix "map" found for tag fragment </code></pre> <p>Now if you extend SupportMapFragment and use a custom view such as this:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:map="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="5dp"&gt; &lt;com.google.android.gms.maps.MapView android:id="@+id/map_view" android:layout_width="match_parent" android:layout_height="match_parent" map:cameraBearing="0" map:cameraTargetLat="54.25" map:cameraTargetLng="-4.56" map:cameraTilt="30" map:cameraZoom="5.6" map:mapType="normal" map:uiCompass="true" map:uiRotateGestures="true" map:uiScrollGestures="true" map:uiTiltGestures="true" map:uiZoomControls="false" map:uiZoomGestures="true"&gt; &lt;/com.google.android.gms.maps.MapView&gt; &lt;/LinearLayout&gt; </code></pre> <p>...then it doesn't complain and the resultant map is correct. For me that raises further problems however as there are no decent examples of how to do this subclassing, you have to do more than override <strong>onCreateView</strong> and when I try to do anything to the map subsequently I get the following:</p> <pre><code>java.lang.IllegalStateException: Map size should not be 0. Most likely, layout has not yet occured for the map view. </code></pre> <p>...even if I wait 30 seconds after the map has appeared.(only first loading)</p>

    1. COWe seem indeed to be sitting in the same boat. I moved on to doing it in the java-code. Thanks for the response, I will try out the custom view.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
