UnsatisfiedLinkError：setMessageHandler（Native Method）

我正在制作一个应用程序，其中使用了一些本地方法，并且这些方法在单独的类中定义。当我在Activity类中创建该类的实例时，会发生这种类型的错误。UnsatisfiedLinkError：setMessageHandler（Native Method）

这是我的活动课

public class LoginActivity extends Activity 
{ 
     PortSipSdk sdk; 
    @Override 
    public void onCreate(Bundle savedInstanceState) 
{ 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.loginview); 
     sdk = PortSipSdk.getInstance();//error is occurs at this line 
     sdk.setOnRegisterListener(this); 
    } 
}

Java类是

public class PortSipSdk { 
    private final String TAG = "PortSipSdk"; 
    private static PortSipSdk instance; 
    private PortSipNetwork mNetAssist; 
    private KeyguardLock mKeyguardLock; 

    private Context mContext; 

    long mSessionID = PortSipErrorcode.INVALID_SESSION_ID; 

    public synchronized static PortSipSdk getInstance() { 
     if (instance == null) { 
      instance = new PortSipSdk();    
     } 
     return instance; 
    } 

    private PortSipSdk() { 
     msgDispatcher = new MainHandler(); 
     setMessageHandler(msgDispatcher); 
     videoRecorder = new PortSipVideoRecoder(); 
    } 


    public native void setMessageHandler(Handler msghandler); 

    // Initialize and register functions 
    private native int initializeSDK(int enum_transport, String agent, 
      String STUNServer, int STUNServerPort); 
}

从getInstance方法中删除syncronized关键字。 –

删除syncronized关键字后，它不起作用 – amardeep

您是否加载了本机库？ – Blackbelt

确保您的NDK二进制文件是在您的APK。
