java - 在 Android 应用程序上初始化后 CircularFifoBuffer 崩溃

Question

经过测试，它可以在非 Android 程序上运行，但在 Android 上初始化后立即崩溃。 Log cat 也不产生任何错误消息。我从 CircularFifoBuffer 找到了这个.

有什么明显的问题吗？

编辑:如果我将 jar 文件添加到 libs 文件夹(不是外部文件夹)，然后将其添加到构建路径，我确实会收到此错误消息。但是，如果我在外部添加 jar 文件，则不会出现此错误。

[2012-08-05 20:56:03 - wifiCollection] Dx warning: Ignoring InnerClasses attribute for an anonymous inner class (org.apache.commons.collections.SequencedHashMap$1) that doesn't come with an associated EnclosingMethod attribute. This class was probably produced by a compiler that did not target the modern .class file format. The recommended solution is to recompile the class from source, using an up-to-date compiler and without specifying any "-target" type options. The consequence of ignoring this warning is that reflective operations on this class will incorrectly indicate that it is not an inner class.

从 logcat 输出来看，您的 apk 中似乎没有包含该类:

08-05 21:12:51.782: E/dalvikvm(1782): Could not find class 'org.apache.commons.collections.buffer.CircularFifoBuffer', referenced from method com.jimmyc.summer.wificollection.WiFiLocationApp$wifiMode.<init>

Add 会说你最好的选择是获取源代码，将其包含在你的项目中并在你的构建环境中重新编译它。
