Android細分錯誤

Question

我們正在為Android開發一個項目，我們的平台基於Arm。 我們發現在dalvik中發生應用程序崩潰的可能性很小。 以下是崩潰日志消息。 我認為分段錯誤是由內存損壞引起的，這是此問題的根本原因，但我不知道如何調試此問題。

任何提示，不勝感激。

問候，

Answer 1

從日志中，我可以看到您正在使用Android 2.3（Gingerbread）。 實際上，此版本在垃圾回收期間存在一個錯誤。 那就是為什么我認為有android本機庫崩潰的原因。

請在這里https://groups.google.com/forum/#!topic/android-ndk/k6rWjsrs_z0看到類似的問題

解決方法-（來自上面的鏈接） ：解決方法是原子存儲對象數組元素。 在Bionic C庫中，bcopy例程與memmove分開實現，而且非常幸運，它原子地移動了字大小的值。 該提交將System.arraycopy切換為使用bcopy而不是memmove。
