Question

我是使用Android原生方法的新手。即使我确保我的armeabi，armeabi-v7a，mips和带有正确* .so文件的x86正确放入文件夹中，我也得到了如下错误。

以下是我加载.so文件的方式：

static{
    try {
        System.loadLibrary("libMimasAr3D");
    } catch (UnsatisfiedLinkError use) {
        Log.e("JNI", "WARNING: Could not load libMimasAr3D.so");
    }
}

额外的东西（我不认为这是主要问题）？

在我加载库的同一文件中，我有这个方法：

public static native void MIMAS_LoadModel(int ppModel);

主要Activity.java：

   //Description: Load the model.
   //Input: pModelPath - A file path to the saved model.
   //Return: A pointer to the object of the model. NULL if loading is failed.
    //Load image to MIMAS_SDK
    MimasJNI.MIMAS_LoadModel("models/model.bin");

请帮助我。提前谢谢！

Answer 1

loadLibrary()使用不带 "lib" 前缀的名称。
如果您不使用RegisterNatives()，则应根据javah处方命名原生图书馆的导出功能，例如Java_com_arzap_mimas_MimasJNI_MIMAS_1LoadModel。
如果本机代码是C ++，请确保导出的函数具有 extern "C" 前缀以防止名称重整。

UnsatisfiedLinkError：找不到.so文件正确放入Eclipse库
