JNI在应用程序中检测到错误：jarray是NULL - 我的代码与否？

标签： android java-native-interface native

目前正在开发一个包含C中的小型本机代码部分的Android应用程序，我有一个JNI错误，我不知道它是否与我的代码相关。

我读了logcat，但我肯定不确定问题是由于我的代码造成的。 logcat中的内容是什么？

以下是我认为相关的logcat部分：

答案 0 :(得分：0)

回答最初的问题：

  • 是的，问题是由于我的C ++代码
  • 我没有找到从logcat
    • 中读取的方法

我只是通过在Java中快速编写函数来确认这是由于我的代码，并且它从未与这个函数崩溃。

正如你可能有这样的问题：https://developer.android.com/ndk/guides/ndk-stack，logcat和ndk-stack理论上应该提供有关崩溃发生位置的信息。不幸的是我无法正确使用ndk-stack。它什么都不输出。也许是因为我用错误的符号文件喂它。我完全不知道。它只是输出：

export default rootReducer = combineReducers({ auth, viewControl, showIntro: showIntro => showIntro }); 。

作为旁注，如果像我一样环境变量没有正确设置可能有用，ndk-stack工具如下：     / Users / homefolder / Library / Android / sdk / ndk-bundle / ndk-stack

符号文件在（我不知道使用哪一个，全部尝试过）：

********** Crash dump: **********

因为我无法使用ndk-stack，所以我用Java重写了这个函数，所有的崩溃都消失了。 有关信息，我试图在C ++代码和JNI调用周围尝试/ catch，但这并没有阻止崩溃发生。
