java.lang.UnsatisfiedLinkError：找不到本机方法：org.cocos2dx.lib.Cocos2dxHelper.nativeSetApkPath：

Question

修改-2

最后修正了错误，请参阅我的回答。

编辑-1

现在创建一个新项目并将其导入到adt
并从property-＆gt; android-＆gt;库中添加src 因为我添加了库编译，现在创建了libcocos2dcpp.so文件

并将其发布到myapp.java文件

System.loadLibrary("cocos2dcpp");

运行它并在模拟器上安装它给出相同的错误

我正在使用cocos2d-2.0-x-2.0.3
NDK - android-ndk-r9d
ANDROID SDK - android-19 使用MAC OS - 版本10.9.4

通过导入项目将我的项目添加到adt。

编辑build_native.sh并添加

# paths
NDK_ROOT="/Users/YourMacName/Documents/android-ndk-r9d"

在文件的开头。

我的Android.mk文件是

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := game_shared

LOCAL_MODULE_FILENAME := libgame

LOCAL_SRC_FILES := hellocpp/main.cpp \

添加了cocos2dx库属性 - ＆gt; java构建路径 - ＆gt;链接源 - ＆gt; src

在myApp.java文件中为load libgame.so文件添加了此代码

static 
    {
        try 
        {
            System.loadLibrary("game");
        }
        catch (UnsatisfiedLinkError ule) 
        {
            Log.e("JNI", "WARNING: Could not load libgame.so");
        }
    }

在清单文件中添加了此代码

<!-- Tell Cocos2dxActivity the name of our .so -->
        <meta-data android:name="android.app.lib_name"
                   android:value="game" />

这是我的应用包

的屏幕截图

它在genymotion emmulator和Android设备错误消息弹出

上成功运行

Unfortunately, myApp has stoped.

并且LogCat中的错误是

我的问题是如何生成libgame.so文件？

我的libs文件夹

中没有生成名为libgame.so的文件

它在iOS中运行良好。

我曾尝试在cocos2dx 2.2.2中创建新的应用程序并且它的工作完美但我的应用程序是在cocos2d-2.0-x-2.0.3中我无法将整个代码转换为cocos2dx 2.2.2因为它也是长。

有很多人发布但没有给出解决方案，我尝试了很多，如果我得到了解决方案，我肯定会发布解决方案。

提前感谢。

Answer 1

经过大量工作后终于得到了答案

你必须运行命令./build_native.sh defore cocos2dx 2.2.2来生成.so文件。

sollution是libgame.so文件未创建

1）在build_native.sh中设置ndk路径

2）从终端运行命令./build_native.sh，得到错误
         In constructor 'CocosDenshion::SimpleAudioEngine::SimpleAudioEngine()':
我不知道为什么但是NDK r9没有编译cpp文件中的LOGD所以我将其从该文件中删除。

3）再次运行命令./build_native.sh，结果是生成了libgame.so文件

4）从eclipse打开应用程序，现在一切正常。

Answer 2

你可以在这里发布你的jni文件吗？例子＆＃34; main.cpp＆＃34;在默认的cocos示例库中。 我猜测提供的命名空间错误，因此Android无法找到正确的JNI方法。

 void Java_org_cocos2dx_lib_Cocos2dxRenderer_nativeInit(JNIEnv*  env, jobject thiz, jint w, jint h)
{
    if (!CCDirector::sharedDirector()->getOpenGLView())
    {
        CCEGLView *view = CCEGLView::sharedOpenGLView();
        view->setFrameSize(w, h);

        AppDelegate *pAppDelegate = new AppDelegate();
        pAppDelegate->setScreenId(screenId);

        delegate = pAppDelegate;
        CCApplication::sharedApplication()->run();
    }
    /*
    else
    {
        ccDrawInit();
        ccGLInvalidateStateCache();

        CCShaderCache::sharedShaderCache()->reloadDefaultShaders();
        CCTextureCache::reloadAllTextures();
        CCNotificationCenter::sharedNotificationCenter()->postNotification(EVNET_COME_TO_FOREGROUND, NULL);
        CCDirector::sharedDirector()->setGLDefaultValues(); 
    }
     */
}
