cocos2d 中使用jni Java 调用 C++ 方法

1.首先是LoadLibrary

cocos2d中的C++代码会编译成一个.so文件，放在安卓目录下的libs/armeabi 下，然后java会load进来，这步我们不用做了，因为cocos2d已经帮我们做好了。

package cb.CbCCBLE;


public class CbCCBLECentralManager {
	
    public static final String TAG = "CbCCBLECentralManager Android";

    
    public native static void bleCenterManagerNotificationChangeState(int oldState, int newState);
    public native static void bleCenterManagerNotificationDidScanOnePeripheral(String peripheralId);
    public native static void bleCenterManagerNotificationDidFinishScanning();
   
}

extern "C"
{
    //test
    void Java_cb_CbCCBLE_CbCCBLECentralManager_bleCenterManagerNotificationChangeState(JNIEnv* env, jobject thiz, jint oldState, jint newState)
    {
        CCLOG("Java_cb_CbCCBLE_CbCCBLECentralManager_bleCenterManagerNotificationChangeState");
     
        CCLOG("oldState:%d, newState:%d", (int)oldState, (int)newState);
    }
    
    
    void Java_cb_CbCCBLE_CbCCBLECentralManager_bleCenterManagerNotificationDidScanOnePeripheral(JNIEnv* env, jobject thiz, jstring peripheralId)
    {
        CCLOG("Java_cb_CbCCBLE_CbCCBLECentralManager_bleCenterManagerNotificationDidScanOnePeripheral");
        std::string peripheralId = JniHelper::jstring2string(peripheralId);
        CCLOG("%s", peripheralId.c_str());
    }
    
    void Java_cb_CbCCBLE_CbCCBLECentralManager_bleCenterManagerNotificationDidFinishScanning(JNIEnv* env, jobject thiz)
    {
        CCLOG("Java_cb_CbCCBLE_CbCCBLECentralManager_bleCenterManagerNotificationDidFinishScanning");
    }

}
