Android信标库编译问题

我试图让Android Beacon Library适用于某个项目，但我遇到了一些问题。

我下载了库，将其添加到eclipse，然后导入了示例项目（https://github.com/AltBeacon/android-beacon-library-reference）。在Linux薄荷上一切都运行良好，所以我基于这个库开发了自己的服务。

然后我与一些在Windows上遇到问题的朋友分享了我的代码。事实上，eclipse并没有显示任何错误，但应用程序崩溃了（示例应用程序和我自己的应用程序）。

所以我试图在Windows上导入项目，应用程序也崩溃了。我们在多台计算机上试过这个。我真的不明白错误的来源。这是logcats：

正如我所说，从linux编译时应用程序运行良好。我试图修改导入的顺序。

你知道这些错误来自哪里吗？

1 个答案:

答案 0 :(得分：0)

我通过更新ADT插件和SDK工具解决了我的问题。

我将ADT从22.6版本更新到23.0.2，因为我无法获得最新版本的SDK工具。

然后，我安装了：

  • Android SDK工具rev 23.0.5
  • Android SDK Platform-tools rev 21
  • Android SDK Build-Tools rev 21.1.1

我还安装了Android API 20和21，但不认为它会改变任何内容。

不要忘记重新启动eclipse并清理工作区。我在4台计算机上试过它，它适用于所有这些计算机。
