    <p>I have a libgdx project using third party libraries (jersey). It compiles fine on the desktop version but crashes on android with "Link of class XXX failed" and "VFY: unable to find class ... " errors.</p> <p>It seems like this exact question comes up a lot here. But I've looked through other answers and have been trying to get this to work for a couple of days now with no luck.</p> <p>I've added libraries to the libs folder and checked that they're ticked in the order and export menu as all the other questions suggest.</p> <p>Here's a minimal project that has the problem. It's the default base project and android project automatically created by libgdx with the jersey library added and a couple of lines in the base project (in MyGdxGame.java) that use the jersey library and cause it to crash on android. <a href="https://dl.dropboxusercontent.com/u/23063759/my-gdx-game.zip" rel="nofollow">https://dl.dropboxusercontent.com/u/23063759/my-gdx-game.zip</a></p> <p>Here's the logcat output i'm getting</p> <pre><code>12-10 21:19:10.531: W/dalvikvm(12940): Link of class 'Lcom/sun/jersey/core/osgi/OsgiRegistry;' failed 12-10 21:19:10.541: I/dalvikvm(12940): Could not find method com.sun.jersey.core.osgi.OsgiRegistry.getInstance, referenced from method com.sun.jersey.core.reflection.ReflectionHelper.getOsgiRegistryInstance 12-10 21:19:10.541: W/dalvikvm(12940): VFY: unable to resolve static method 10327: Lcom/sun/jersey/core/osgi/OsgiRegistry;.getInstance ()Lcom/sun/jersey/core/osgi/OsgiRegistry; 12-10 21:19:10.541: D/dalvikvm(12940): VFY: replacing opcode 0x71 at 0x0008 12-10 21:19:10.541: I/dalvikvm(12940): Failed resolving Lcom/sun/jersey/core/osgi/OsgiRegistry; interface 2368 'Lorg/osgi/framework/SynchronousBundleListener;' 12-10 21:19:10.541: W/dalvikvm(12940): Link of class 'Lcom/sun/jersey/core/osgi/OsgiRegistry;' failed 12-10 21:19:10.541: W/dalvikvm(12940): VFY: unable to find class referenced in signature (Lcom/sun/jersey/core/osgi/OsgiRegistry;) 12-10 21:19:10.631: W/dalvikvm(12940): threadid=11: thread exiting with uncaught exception (group=0x41560b 90) 12-10 21:19:10.672: D/dalvikvm(12940): GC_FOR_ALLOC freed 563K, 7% free 9262K/9856K, paused 37ms, total 3 7ms 12-10 21:19:10.672: E/AndroidRuntime(12940): FATAL EXCEPTION: GLThread 792 12-10 21:19:10.672: E/AndroidRuntime(12940): Process: com.me.mygdxgame, PID: 12940 12-10 21:19:10.672: E/AndroidRuntime(12940): java.lang.NullPointerException 12-10 21:19:10.672: E/AndroidRuntime(12940): at javax.ws.rs.core.MediaType.valueOf(MediaType.java:119) 12-10 21:19:10.672: E/AndroidRuntime(12940): at com.sun.jersey.api.client.PartialRequestBuilder.type(PartialRequestBuilder.java:92) 12-10 21:19:10.672: E/AndroidRuntime(12940): at com.sun.jersey.api.client.WebResource.type(WebResource.java:349) 12-10 21:19:10.672: E/AndroidRuntime(12940): at com.me.mygdxgame.MyGdxGame.create(MyGdxGame.java:48) 12-10 21:19:10.672: E/AndroidRuntime(12940): at com.badlogic.gdx.backends.android.AndroidGraphics.onSurfaceChanged(AndroidGraphics.java:292) 12-10 21:19:10.672: E/AndroidRuntime(12940): at android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1512) 12-10 21:19:10.672: E/AndroidRuntime(12940): at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1240) </code></pre> <p>In the example i gave i'm using jersey, but the same thing happened when i switched it for a different library. I feel like there's something stupid i'm missing. But I just can't find it.</p>

    1. CODo you use multiple projects? For instance a desktop project, and then a small Android project that links to the desktop one? If so, make sure you check all the Order and Export boxes in the Android project.

    2. COthere's a base project used as a library for platform specific projects. I've tried various configurations. I've got them all ticked in the order and export pane in the android project. I'm not sure if i'm meant to do the same in the base project or not but tried with and without.

    3. COI took a look at it, but I'm not at a computer that can compile it. Maybe try removing all the redundant .jars from the Android project? (so only gdx-backend-android.jar remains)

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.
