Android-NDK "java.lang.UnsatisfiedLinkError"

Question

나는 NDK와 c, C++가 처음이다. 그래서 내가 잘못하면 나를 용서해주십시오.

는 내가 무엇입니까 로그인 고양이의 오류가 나는 lib 폴더에 libfirst-opengl.so 라이브러리를 볼 수 있습니다 NDK 빌드 후 java.lang.UnsatisfiedLinkError 이

들으은 JAVA에 대한 내 코드입니다

public class MainActivity extends Activity { 
    private GLSurfaceView mGLSurfaceView; 

    /** Called when the activity is first created. */ 
    static{ 
     System.loadLibrary("first-opengl"); 
    } 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     // Set window full screen and remove title bar 
     this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
     getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
       WindowManager.LayoutParams.FLAG_FULLSCREEN); 

     // Create the EGL surface (set OpenGL version 2.0) and override the 
     // renderer with our custom one 
     mGLSurfaceView = new GLSurfaceView(this); 
     mGLSurfaceView.setEGLContextClientVersion(2); 
     mGLSurfaceView.setRenderer(new MySurfaceViewRenderer()); 
     setContentView(mGLSurfaceView); 
    } 

    @Override 
    public void onPause() { 
     super.onPause(); 
     mGLSurfaceView.onPause(); 
    } 

    @Override 
    public void onResume() { 
     super.onResume(); 
     mGLSurfaceView.onResume(); 
    } 

    public class MySurfaceViewRenderer implements Renderer { 

     public void onSurfaceCreated(GL10 unused, EGLConfig config) { 
      JNIOnSurfaceCreated(); 
     } 

     public void onSurfaceChanged(GL10 unused, int w, int h) { 
      JNIOnSurfaceChanged(w, h); 
     } 

     public void onDrawFrame(GL10 unused) { 
      JNIOnDrawFrame(); 
     } 

     private native void JNIOnSurfaceCreated(); 

     private native void JNIOnSurfaceChanged(int w, int h); 

     private native void JNIOnDrawFrame(); 
    } 

}

JNIEXPORT void JNICALL Java_com_nix_opendk_MainActivity_JNIOnDrawFrame 

아마해야합니다 :

하지 MainActivity 때문에 MySurfaceViewRenderer 렌더러 클래스에있는 당신

Answer 1

네이티브 기능 감사

JNIEXPORT void JNICALL Java_com_nix_opendk_MainActivity_MySurfaceViewRenderer_JNIOnDrawFrame 

내가 내부에 액세스하려고하지 않았습니다 클래스의 jni하지만 사양을 기반으로 소리 것 같습니다.
