swarm和libgdx演示

Question

我正在学习一个集成swarm和libgdx的教程。链接在这里http://swarmconnect.com/admin/docs/libgdx。

我下载的源代码提供了http://swarmconnect.com/login?redirect=%2Fimages%2Fdocs%2Fexample_libgdx_swarm_done.zip。构建时没有发生任何错误。当我尝试在模拟器中运行android应用程序时，“不幸的是，XXX已停止”将弹出。而logcat是

上面写着

但我将swarm项目添加到了superjumper-android项目中。有人遇到过类似的问题吗？

Answer 1

看起来Swarm.jar并没有包含在APK中。

确保您已经完成了本教程中的以下步骤：

• 将superjumper-android项目链接到SwarmConnect库，方法是转到superjumper- Android的属性>Android>添加...>选择群组连接/库>单击Apply >单击OK
• 将superjumper项目链接到Swarm.jar，方法是转到superjumper的属性> Java Build Path > Libraries选项卡> Add JARs...>选择群组连接/库/群组.jar>单击OK

您可能需要通过superjumper-android项目将" Swarm.jar“标记为"exported”：Properties > Java Build Path > Order and export Tab >确保选中Swarm.jar进行导出。Android SDK团队不断调整(即打破) Android项目的构建流程，其中包括其他项目和库。如果您正在使用SDK v22，请参阅：Libraries do not get added to APK anymore after upgrade to ADT 22

最后，如果这些都没有帮助，请检查How can I use external JARs in an Android project?，它有许多不同的答案(对于许多不同的方式，无法找到jar文件)。
