    <p>EDIT: For those struggling with this, checkout <a href="https://docs.google.com/document/pub?id=19nQzvKP-CVLd7_VrpwnHfl-AE9fjbJySowONZZtNHzw" rel="nofollow">this link</a>. Follow it carefully, but it does work! The crucial part is using <code>keytool</code> to generate your SHA1 hash against your debug keystore. Also, don't forget to add one for release too!</p> <p>I've been trying to setup Google Maps Android API v2 and after setting everything up as said I'm getting this runtime exception <code>ClassNotFound</code>:</p> <pre><code>01-02 16:29:07.927: E/AndroidRuntime(12508): FATAL EXCEPTION: main 01-02 16:29:07.927: E/AndroidRuntime(12508): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.app/com.example.app.MapActivity}: android.view.InflateException: Binary XML file line #6: Error inflating class fragment 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1659) 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1675) 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.app.ActivityThread.access$1500(ActivityThread.java:121) 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:943) 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.os.Handler.dispatchMessage(Handler.java:99) 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.os.Looper.loop(Looper.java:130) 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.app.ActivityThread.main(ActivityThread.java:3701) 01-02 16:29:07.927: E/AndroidRuntime(12508): at java.lang.reflect.Method.invokeNative(Native Method) 01-02 16:29:07.927: E/AndroidRuntime(12508): at java.lang.reflect.Method.invoke(Method.java:507) 01-02 16:29:07.927: E/AndroidRuntime(12508): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:866) 01-02 16:29:07.927: E/AndroidRuntime(12508): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:624) 01-02 16:29:07.927: E/AndroidRuntime(12508): at dalvik.system.NativeStart.main(Native Method) 01-02 16:29:07.927: E/AndroidRuntime(12508): Caused by: android.view.InflateException: Binary XML file line #6: Error inflating class fragment 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:581) 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.view.LayoutInflater.rInflate(LayoutInflater.java:623) 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.view.LayoutInflater.inflate(LayoutInflater.java:408) 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.view.LayoutInflater.inflate(LayoutInflater.java:320) 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.view.LayoutInflater.inflate(LayoutInflater.java:276) 01-02 16:29:07.927: E/AndroidRuntime(12508): at com.android.internal.policy.impl.PhoneWindow.setContentView(PhoneWindow.java:227) 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.app.Activity.setContentView(Activity.java:1657) 01-02 16:29:07.927: E/AndroidRuntime(12508): at com.example.app.MapActivity.onCreate(MapActivity.java:11) 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1623) 01-02 16:29:07.927: E/AndroidRuntime(12508): ... 11 more 01-02 16:29:07.927: E/AndroidRuntime(12508): Caused by: java.lang.ClassNotFoundException: android.view.fragment in loader dalvik.system.PathClassLoader[/data/app/com.example.app-1.apk] 01-02 16:29:07.927: E/AndroidRuntime(12508): at dalvik.system.PathClassLoader.findClass(PathClassLoader.java:240) 01-02 16:29:07.927: E/AndroidRuntime(12508): at java.lang.ClassLoader.loadClass(ClassLoader.java:551) 01-02 16:29:07.927: E/AndroidRuntime(12508): at java.lang.ClassLoader.loadClass(ClassLoader.java:511) 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.view.LayoutInflater.createView(LayoutInflater.java:471) 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.view.LayoutInflater.onCreateView(LayoutInflater.java:549) 01-02 16:29:07.927: E/AndroidRuntime(12508): at com.android.internal.policy.impl.PhoneLayoutInflater.onCreateView(PhoneLayoutInflater.java:66) 01-02 16:29:07.927: E/AndroidRuntime(12508): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:568) 01-02 16:29:07.927: E/AndroidRuntime(12508): ... 20 more </code></pre> <p>Has anyone ever come across this before?</p> <p>XML:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;fragment xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.MapFragment"/&gt; </code></pre> <p>MapActivity:</p> <pre><code>import android.os.Bundle; import android.app.Activity; public class MapActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_map); } } </code></pre>

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).
