不满意的链接错误Android Eclipse

Question

我正在尝试创建一个Android项目，该项目使用我使用cygwin进行编译的.so文件加载专门加载本机库的本机openal文件，在我的onCreate方法中，我有以下代码

System.loadLibrary("openal.so");

我编译的库文件在我的libs / armeabi文件夹中

我的两个本机代码文件由一个.c文件组成，其中

#include "com_example_helloopenal_MainActivity.h"

JNIEXPORT jint JNICALL Java_com_example_helloopenal_MainActivity_play
(JNIEnv * env, jobject obj, jstring filename) {
return 0;
}

和一个.h文件，其中包含

/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class com_example_helloopenal_MainActivity */

#ifndef _Included_com_example_helloopenal_MainActivity
#define _Included_com_example_helloopenal_MainActivity
#ifdef __cplusplus
extern "C" {
#endif
/*
* Class:     com_example_helloopenal_MainActivity
* Method:    play
* Signature: (Ljava/lang/String;)I
*/
JNIEXPORT jint JNICALL Java_com_example_helloopenal_MainActivity_play
(JNIEnv *, jobject, jstring);

#ifdef __cplusplus
}
#endif
#endif

此时在onCreate中调用并写入.c文件的方法play应该在log cat中返回0，但是应用程序崩溃并显示以下错误消息

01-20 16：11：51.299：E / AndroidRuntime（10842）：java.lang.UnsatisfiedLinkError：无法从加载程序dalvik.system.PathClassLoader [DexPathList [[zip file“ / data / app / com。 example.helloopenal-2.apk“]，nativeLibraryDirectories = [/ data / app-lib / com.example.helloopenal-2，/ vendor / lib，/ system / lib，/ system / lib / arm]]]：findLibrary返回空值

我是ndk开发的新手，因此对这个问题的原因或性质有任何启发

Answer 1

您应该将其称为System.loadLibrary("openal"); 没有这样的扩展
