android - 启动Android应用程序时出现运行时异常

Question

我试图从 eclipse 启动我的 android 应用程序，但每当我启动该应用程序时，它就会卡住，我在 LogCat 中收到以下错误

更多背景:我基本上是想在我的应用程序中添加这个库。 http://code.google.com/p/little-fluffy-location-library/

如说明中所述，我已将这行代码添加到我的应用程序的 onCreate 方法中。

LocationLibrary.initialiseLibrary(getBaseContext(), 60 * 1000, 2 * 60 * 1000, "mobi.littlefluffytoys.littlefluffytestclient");

导致错误。如果我删除这行代码，应用程序运行正常。

有人可以帮我解决这个错误吗？提前致谢。

Answer 1

我怀疑这是您在库文档中缺少的步骤 --

To use the library, add littlefluffylocationlibrary.jar as an external JAR into your Android project. In Eclipse, this is easiest done by creating a folder in your project called libs, copying the file into it, refresh the project, right-click the .jar file, and then select Add to build path.

验证您是否将 jar 文件复制到您的 libs 目录并且它位于您的构建路径中(这在 ADT 的更高版本中自动完成)
