似乎以下代码是错误的，因为在第一次调用时代码运行良好，但是第二次VM会终止调用者应用程序。
JNIEXPORT jint JNICALL Java_com_voice4facebook_MegaRecorderActivity_startMix(JNIEnv* env, jobject obj, jobjectArray params) {
int stringCount = (*env)->GetArrayLength(env, params);
char * argv[stringCount];
int i = 0;
while (i < stringCount) {
jstring string = (jstring)(*env)->GetObjectArrayElement(env, params, i);
const char *rawString = (*env)->GetStringUTFChars(env, string, 0);
argv[i] = rawString;
// Don't forget to call `ReleaseStringUTFChars` when you're done
i++;
}
main(stringCount, argv);
i = 0;
while (i < stringCount)
{
jstring string = (jstring)(*env)->GetObjectArrayElement(env, params, i);
(*env)->ReleaseStringUTFChars (env, string, argv[i++]);
}
success = 1;
return 0;
}

答案 0 :(得分：1)
完成后，您需要释放字符串。请在success = 1：
i = 0;
while (i < stringCount)
{
jstring string = (jstring)(*env)->GetObjectArrayElement(env, params, i);
(*env)->ReleaseStringUTFChars (env, string, argv[i++]);
}

日志中的第一个条目是提示问题可能是什么
02-14 16:18:19.625 17098 17098 I DEBUG : signal 11 (SIGSEGV), code 1 (SEGV_MAPERR),

该地址看起来像是调试内存地址。
来自wikipedia：
当检测到本机堆损坏时，Android libc abort（）函数使用0xDEADBAAD（＆＃34;死坏＆＃34;）。
这通常意味着您已经free或delete了解了malloc或new 。也许在你的main函数中你试图删除输入数组中的变量？
