不滿意的鏈接錯誤Android Eclipse

Question

我正在嘗試創建一個Android項目，該項目使用我使用cygwin進行編譯的.so文件加載專門加載本機庫的本機openal文件，在我的onCreate方法中，我有以下代碼

System.loadLibrary("openal.so");

我編譯的庫文件在我的libs / armeabi文件夾中

我的兩個本機代碼文件由一個.c文件組成，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;
}

和一個.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

此時在onCreate中調用並寫入.c文件的方法play應該在log cat中返回0，但是應用程序崩潰並顯示以下錯誤消息

01-20 16：11：51.299：E / AndroidRuntime（10842）：java.lang.UnsatisfiedLinkError：無法從加載程序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開發的新手，因此對這個問題的原因或性質有任何啟發

Answer 1

您應該將其稱為System.loadLibrary("openal"); 沒有這樣的擴展
