Unity Android : no non-static method with name

Question

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:

Please give me a hand!!!

Solution

I believe it is because you have not declared your manifest correctly so it is still using the normal UnityPlayerActivity instead of your custom one.

Specifically adding this inside the activity tag in the manifest:

    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>

Check out the example that Unity gives here: https://docs.unity3d.com/Manual/AndroidUnityPlayerActivity.html

Could you first check that your jo is really has a type WXEntryActivity. Maybe calling jo.Call<AndroidJavaClass>("getClass").Call<string>("toString‌​")

I've the correct manifest (as you point it) and I've stilling the same issue, any idea?
