I am making a Android plugin demo for unity,which when I click the button,it will launch another application.I can build an apk and install it to my device.However,when I click the button,nothing happened but sayings:Unity: AndroidJavaException: java.lang.NoSuchMethodError: no non-static method with name='shareToWX' Here is Android code: public class WXEntryActivity extends UnityPlayerActivity implements IWXAPIEventHandler { private static final String APP_ID=""; private static final String APP_SECRET=""; private static IWXAPI api; private static final int WXSceneSession=0; private static final int WXSceneTimeLine=1; private static final int WXSceneFavorite=2; public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); api= WXAPIFactory.createWXAPI(this,APP_ID,true); api.registerApp(APP_ID); api.handleIntent(getIntent(),this); } public void shareToWX(String text,int scene){ WXWebpageObject webpage=new WXWebpageObject(); webpage.webpageUrl="www.baidu.com"; WXMediaMessage msg =new WXMediaMessage(webpage); msg.title="网页标题"; msg.description="描述"; Bitmap thumb=BitmapFactory.decodeResource(getResources(), R.drawable.test); //msg.thumbData= SendMessageToWX.Req req=new SendMessageToWX.Req(); req.transaction=buildTransaction("webpage"); req.message=msg; switch (scene){ case WXSceneFavorite: req.scene=SendMessageToWX.Req.WXSceneFavorite; break; case WXSceneTimeLine: req.scene=SendMessageToWX.Req.WXSceneTimeline; break; case WXSceneSession: req.scene=SendMessageToWX.Req.WXSceneSession; break; } api.sendReq(req); } And here is my unity code: public class test : MonoBehaviour { public GameObject btnObj; // Use this for initialization void Start () { Button button = btnObj.GetComponent<Button>(); button.onClick.AddListener(share); } // Update is called once per frame void Update () { } void share() { AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer"); AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity"); jo.Call("shareToWX", "unity test",0); } } Manifest.xml: <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.yrgame.wjqpyx"> <application android:allowBackup="true" android:label="@string/app_name" android:supportsRtl="true"> <activity android:name="com.yrgame.wjqpyx.wxapi.WXEntryActivity"/> </application> </manifest> Error: I/Unity: AndroidJavaException: java.lang.NoSuchMethodError: no non-static method with name='shareToWX' signature='(Ljava/lang/String;I)V' in class Lcom.unity3d.player.UnityPlayerActivity; java.lang.NoSuchMethodError: no non-static method with name='shareToWX' signature='(Ljava/lang/String;I)V' in class Lcom.unity3d.player.UnityPlayerActivity; at com.unity3d.player.ReflectionHelper.getMethodID(Unknown Source) at com.unity3d.player.UnityPlayer.nativeRender(Native Method) at com.unity3d.player.UnityPlayer.c(Unknown Source) at com.unity3d.player.UnityPlayer$c$1.handleMessage(Unknown Source) at android.os.Handler.dispatchMessage(Handler.java:98) at android.os.Looper.loop(Looper.java:136) at com.unity3d.player.UnityPlayer$c.run(Unknown Source) at UnityEngine.AndroidJNISafe.CheckException () [0x00000] in <filename unknown>:0 at UnityEngine.AndroidJNISafe.CallStaticObjectMethod (IntPtr clazz, IntPtr methodID, UnityEngine.jvalue[] args) [0x00000] in <filename unknown>:0 at UnityEngine.AndroidReflection.GetMetho Please give me a hand!!!

    @Override public void onConfigurationChanged(Configuration newConfig)

    }

    // Notify Unity of the focus change.
    @Override public void onWindowFocusChanged(boolean hasFocus)

    }

    // For some reason the multiple keyevent type is not supported by the ndk.
    // Force event injection by overriding dispatchKeyEvent().
    @Override public boolean dispatchKeyEvent(KeyEvent event)
    {
        if (event.getAction() == KeyEvent.ACTION_MULTIPLE)
            return mUnityPlayer.injectEvent(event);
        return super.dispatchKeyEvent(event);
    }

    // Pass any events not handled by (unfocused) views straight to UnityPlayer
    @Override public boolean onKeyUp(int keyCode, KeyEvent event)     { return mUnityPlayer.injectEvent(event); }
    @Override public boolean onKeyDown(int keyCode, KeyEvent event)   { return mUnityPlayer.injectEvent(event); }
    @Override public boolean onTouchEvent(MotionEvent event)          { return mUnityPlayer.injectEvent(event); }
    /*API12*/ public boolean onGenericMotionEvent(MotionEvent event)  { return mUnityPlayer.injectEvent(event); }

    public void receiveStr(String str) {
        Log.e(this.toString(), "receiveStr=" + str);
    }
}

Unity method code and Android method code must match. ex: Unity:"receiveStr" == Android="receiveStr"
