    <p>I have a project which uses a <code>WelcomeActivity</code> which extends <code>FragmentActivity</code>. I use the support library, so <code>android-support-v4.jar</code> is in the <code>libs</code> folder. When I run this app, there are no problems.</p> <p>However, I want to add ActionBarSherlock to the project. In the ABS project I use <code>actionbarsherlock-plugin-maps-4.1.0.jar</code> and <code>android-support-v4-r6-googlemaps.jar</code> in the <code>libs</code> folder. In my app project I add the ABS library, and when I try to run the app, this error occurs:</p> <pre><code>UNEXPECTED TOP-LEVEL EXCEPTION: java.lang.IllegalArgumentException: already added: Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoStubImpl; </code></pre> <p>To solve this, I removed the <code>android-support-v4.jar</code> from my app's <code>libs</code> folder. When I now start my app, the app crashes with this logcat:</p> <pre><code>08-01 18:59:11.182: W/dalvikvm(13338): Unable to resolve superclass of Landroid/support/v4/app/FragmentActivity; (620) 08-01 18:59:11.182: W/dalvikvm(13338): Link of class 'Landroid/support/v4/app/FragmentActivity;' failed 08-01 18:59:11.182: W/dalvikvm(13338): Unable to resolve superclass of Lcom/myapp/welcome/WelcomeActivity; (109) 08-01 18:59:11.182: W/dalvikvm(13338): Link of class 'Lcom/myapp/welcome/WelcomeActivity;' failed 08-01 18:59:11.182: E/dalvikvm(13338): Could not find class 'com.myapp.welcome.WelcomeActivity', referenced from method com.myapp.MainDispatcherActivity.startWelcomeActivity 08-01 18:59:11.182: W/dalvikvm(13338): VFY: unable to resolve const-class 690 (Lcom/myapp/welcome/WelcomeActivity;) in Lcom/myapp/MainDispatcherActivity; 08-01 18:59:11.182: D/dalvikvm(13338): VFY: replacing opcode 0x1c at 0x0002 08-01 18:59:11.182: D/dalvikvm(13338): VFY: dead code 0x0004-000b in Lcom/myapp/MainDispatcherActivity;.startWelcomeActivity ()V 08-01 18:59:11.182: D/AndroidRuntime(13338): Shutting down VM 08-01 18:59:11.182: W/dalvikvm(13338): threadid=1: thread exiting with uncaught exception (group=0x40015560) 08-01 18:59:11.182: E/AndroidRuntime(13338): FATAL EXCEPTION: main 08-01 18:59:11.182: E/AndroidRuntime(13338): java.lang.NoClassDefFoundError: com.myapp.welcome.WelcomeActivity 08-01 18:59:11.182: E/AndroidRuntime(13338): at com.myapp.MainDispatcherActivity.startWelcomeActivity(MainDispatcherActivity.java:33) 08-01 18:59:11.182: E/AndroidRuntime(13338): at com.myapp.MainDispatcherActivity.startProperActivity(MainDispatcherActivity.java:26) 08-01 18:59:11.182: E/AndroidRuntime(13338): at com.myapp.MainDispatcherActivity.onCreate(MainDispatcherActivity.java:19) 08-01 18:59:11.182: E/AndroidRuntime(13338): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 08-01 18:59:11.182: E/AndroidRuntime(13338): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1611) 08-01 18:59:11.182: E/AndroidRuntime(13338): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1663) 08-01 18:59:11.182: E/AndroidRuntime(13338): at android.app.ActivityThread.access$1500(ActivityThread.java:117) 08-01 18:59:11.182: E/AndroidRuntime(13338): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:931) 08-01 18:59:11.182: E/AndroidRuntime(13338): at android.os.Handler.dispatchMessage(Handler.java:99) 08-01 18:59:11.182: E/AndroidRuntime(13338): at android.os.Looper.loop(Looper.java:130) 08-01 18:59:11.182: E/AndroidRuntime(13338): at android.app.ActivityThread.main(ActivityThread.java:3683) 08-01 18:59:11.182: E/AndroidRuntime(13338): at java.lang.reflect.Method.invokeNative(Native Method) 08-01 18:59:11.182: E/AndroidRuntime(13338): at java.lang.reflect.Method.invoke(Method.java:507) 08-01 18:59:11.182: E/AndroidRuntime(13338): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:862) 08-01 18:59:11.182: E/AndroidRuntime(13338): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:620) 08-01 18:59:11.182: E/AndroidRuntime(13338): at dalvik.system.NativeStart.main(Native Method) </code></pre> <p>How can I fix this?</p> <p><strong>Edit</strong><br> I have another project which uses the same ABS library, and runs fine. I have no idea what I've done differently, or which settings are wrong.</p>

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).
