    <p>I need to create an Android library which I can include as a jar in any Android application. I use NetBeans 6.8, the nbandroid plugin, and the Android SDK.</p> <p>The steps I took so far are:</p> <p>1) Create the library project, with android.jar included to have access to Android classes (the library uses android.util.Log and other Android classes).</p> <p>2) Compile the library as a jar.</p> <p>3) Add the library's jar to the Android application (right-click on Libraries under the project node and add the jar).</p> <p><del>4) Add &lt;uses-library&gt; to the Android manifest.</del> (erroneous and unnecessary)</p> <p>Step 3 at least allows me to reference the library's classes in the application's source code, but the classes don't seem to actually be included at compile time. When I run the application, I get the following error in the log.</p> <pre><code>I/dalvikvm( 349): Could not find method mylibrarypackage.MyClass.myMethod, referenced from method myapplicationpackage.HomeActivity.onCreate W/dalvikvm( 349): VFY: unable to resolve static method 985: Lmylibrarypackage/MyClass;.myMethod ()V D/dalvikvm( 349): VFY: replacing opcode 0x71 at 0x000a D/dalvikvm( 349): Making a copy of Lmyapplicationpackage/HomeActivity;.onCreate code (160 bytes) D/AndroidRuntime( 349): Shutting down VM W/dalvikvm( 349): threadid=3: thread exiting with uncaught exception (group=0x4001b188) E/AndroidRuntime( 349): Uncaught handler: thread main exiting due to uncaught exception E/AndroidRuntime( 349): java.lang.NoClassDefFoundError: mylibrarypackage.MyClass E/AndroidRuntime( 349): at myapplicationpackage.HomeActivity.onCreate(HomeActivity.java:58) E/AndroidRuntime( 349): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) E/AndroidRuntime( 349): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2417) E/AndroidRuntime( 349): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2470) E/AndroidRuntime( 349): at android.app.ActivityThread.access$2200(ActivityThread.java:119) E/AndroidRuntime( 349): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1821) E/AndroidRuntime( 349): at android.os.Handler.dispatchMessage(Handler.java:99) E/AndroidRuntime( 349): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime( 349): at android.app.ActivityThread.main(ActivityThread.java:4310) E/AndroidRuntime( 349): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 349): at java.lang.reflect.Method.invoke(Method.java:521) E/AndroidRuntime( 349): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) E/AndroidRuntime( 349): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) E/AndroidRuntime( 349): at dalvik.system.NativeStart.main(Native Method) </code></pre> <p>Do I have to add the library to the build path somewhere else? Am I missing something?</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.

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