我有一个通过JNI绑定使用C库的应用程序。 在iOS上使用相同的C库没有任何问题，它已经使用了大约2年。
我尝试在Android上实现相同的库，一般来说，一切都按预期工作，但应用程序在调用JNI代码后随机崩溃。
我的意思是我调用库，我接收数据，我用数据做一些事情[比如屏幕上的更新按钮]，然后等待进一步的用户输入。 通话结束后大约200-300ms后，我的应用程序崩溃了。随机，我的意思是它崩溃了3次中的1次。有时在第一次调用之后，有时在第4次之后等等。所有时间我都使用相同的数据集，因此这个问题不是特定于数据的。
不幸的是，我得到的错误也是随机的。这让我相信，它必须是内存管理的东西，但该死......我根本不知道如何调试它。
以下是我得到的错误的几个例子。

我不得不承认，我讨厌这种错误。我不知道在哪里寻找解决方案。
现在有点关于图书馆：
它需要一个zip文件，从中解压缩xml文件并将数据从xml解析为一个结构，然后用于生成包含所有数据的对象。
基本上就是这样。
在JNI类中，我保持JNIEnv的值，因为有一种情况我必须从C调用java类，但在这种情况下不是。我做的电话仅限于我上面给出的描述。
此外，这种情况在第一次通话时经常发生，所以我怀疑它与此有什么关系。
我能提供什么其他方法来确定崩溃的原因吗？
我有点厌倦了这个问题，如果由我决定我只会在java中重写lib，但是获取C lib的整个想法是在所有平台上运行一个代码。
我将不胜感激任何帮助。
EDIT 我能够从调用中删除大量代码，以确定应用程序崩溃的最简单方法。 现在我只有一个函数，当被调用时会[随机]破坏应用程序，当没有被调用时，将永远不会这样做。
这里是我称之的JNI代码，非常简单。也许我的错误比我简单得多。
jlong Java_com_mycompany_product_ProdJNI_openProdBook(JNIEnv* env, jobject this, jstring jprname) {
// set the jvm variable so other C threads can access java virtual machine
(*env)->GetJavaVM(env, &jvm);
const char *prodname = (*env)->GetStringUTFChars(env, jprname, NULL);
unsigned long ret = product_open(prodname);
(*env)->ReleaseStringUTFChars(env, jprname, prodname);
return ret;
}

这不是一个答案，但评论太长了。我会注意到两件事。首先，您的评论“在调用后大约200-300ms后，我的应用程序崩溃[随机]”，其中两个失败的堆栈跟踪包括您的本机库libmylibjni.so：
06-03 13:35:37.991 6307-6307/? A/DEBUG: #00 pc 00047b26 /system/lib/libc.so (pthread_mutex_lock+1)

据推测，这是从libart.so启动的本机线程运行的，如您在堆栈底部一直看到的那样：
06-03 13:35:37.993 6307-6307/? A/DEBUG: #63 pc 001ca845 /system/lib/libart.so (_ZN3art11interpreterL7ExecuteEPNS_6ThreadEPKNS_7DexFile8CodeItemERNS_11ShadowFrameENS_6JValueEb+368)
虽然你没有向我们提供你的任何代码，但我会冒险理论并说你在C ++和Java之间交换内存缓冲区，其中一个是破坏内存，或者没有遵守互斥锁控制共享数据（可能导致损坏）。因此堆操作期间崩溃或其他无关的代码。
第二个理论是libart.so has a bug，这会引起你的麻烦。
如果您要分享一些代码，我们可能会提供更多帮助。

问题是，为什么要调用GetJavaVM？如果你从C调用Java，这是有道理的。看看这里：
http://jnicookbook.owsiak.org/recipe-no-027/
我按照以下方式为您制作JNI代码：
jlong Java_com_mycompany_product_ProdJNI_openProdBook(JNIEnv* env, jobject this, jstring jprname) {
const char *prodname = (*env)->GetStringUTFChars(env, jprname, NULL);
unsigned long ret = product_open(prodname);
(*env)->ReleaseStringUTFChars(env, jprname, prodname);
return ret;
}
它应该没有任何问题。
你可以在这里测试一下：
http://jnicookbook.owsiak.org/recipe-No-009/
其中，简单的代码在Java和C之间传递Java字符串。
与JNI玩得开心！
