CircularFifoBuffer在Android應用上初始化後崩潰

經過測試，它在非Android程序上工作，但在Android上初始化後立即崩潰。日誌貓也不會產生任何錯誤消息。我從找到了這個。CircularFifoBuffer在Android應用上初始化後崩潰

任何明顯的問題？

編輯：如果我將jar文件添加到libs文件夾（而不是外部），然後將其添加到構建路徑中，我會得到此錯誤消息。如果我在外部添加jar文件，這個錯誤不存在。

[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.

你如何在Android中添加CircularFifoBuffer？ – 2012-08-06 03:33:30

它是作爲外部jar導入的，爲什麼我從apache導入統計信息庫。有什麼特別的我必須爲android – jimmyC 2012-08-06 03:40:53

做什麼你可以發佈你的logcat輸出？我假設你在logcat中看到「Starting ..」mesg，但沒有看到「Error：」mesg？ – Maks 2012-08-06 03:56:31

從logcat的輸出，它看起來像沒有被包含在您的apk類：

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>

添加會說你最好的選擇將是獲得源代碼，包括在您的項目，並把它在您的構建環境中重新編譯。

它爲什麼會編譯，然後 – jimmyC 2012-08-06 04:15:43

編譯後，編譯器（Eclipse中的ecj或JDK附帶的javac）將*代碼與jar文件中的類鏈接起來沒有問題，但是它的Davlik VM有問題（無法加載Apache類），這可能是因爲dex工具將類文件字節碼交叉編譯爲其自己的字節碼的方式。 – Maks 2012-08-06 04:20:11

謝謝，我得到它的工作。我仍然收到來自Edit1的錯誤消息，但我認爲這可以通過一些挖掘來刪除。至少它正在編譯而不是崩潰。 – jimmyC 2012-08-06 05:02:56

檢查你的庫JAR依賴。你可能會錯過一些東西。（如你所說，你已經在Android之外測試過它了）。

您可能需要從源代碼構建才能使其正常工作，因爲可能使用不同版本的Java構建JAR（Android支持Java 6不是7）。
