如何解釋Android本機代碼中的JNI錯誤？這個錯誤的含義是什麼？

我的Android應用程序崩潰在JNI代碼和LogCat顯示以下輸出，這可能是什麼原因導致這種失敗？我如何管理JNI內部的本機內存？如何解釋Android本機代碼中的JNI錯誤？這個錯誤的含義是什麼？

即使我們的顯示名稱是相同的... lolz ...我手動嘗試並且問題有點解決...但是必須有一些這些類型的錯誤的參考或一些工具來跟蹤本機內存分配... – aProgrammer 2012-07-16 07:58:14

Yaa。 ..你發佈的問題有點小，我以前面臨...仍然研究將幫助它解決你的問題。 – 2012-07-16 08:02:58

正是從這個問題是在JNI開始就明確，我穿過檢查本機代碼，發現我所用memset()和memcpy() in JNI錯誤的字節數。我糾正了代碼並解決了問題。

對於其他面臨同樣問題的人，「請檢查您的內存使用情況在本地代碼。」
