[ERROR] E/MicroMsg.SDK.MMessageAct: send fail, target ActivityNotFound Android

我的代码：

@Kroll.method

  public void regToWx()

  {

    Log.d(current_module, "=======start to register to wechat==========");

    api = WXAPIFactory.createWXAPI(getActivity(),null);

    Log.d(current_module, "=======create api after====="+api);

    api.registerApp(APP_ID);

    Log.d(current_module, "====注册微信成功======");

  }

  @Kroll.method

  public void sendMessageToWx()

  {

    Log.d(current_module, "====下面发送消息给微信======");

    WXTextObject text_obj = new WXTextObject();

    text_obj.text="we are young!!!";

    Log.d(current_module, "====构造Media Message======");

    WXMediaMessage msg_obj = new WXMediaMessage();

    msg_obj.mediaObject = text_obj;

    msg_obj.description = "this is desciption";

    Log.d(current_module, "====构造 Request======");

    SendMessageToWX.Req req = new SendMessageToWX.Req();

    req.transaction = String.valueOf(System.currentTimeMillis());

    req.message = msg_obj;

    req.scene = SendMessageToWX.Req.WXSceneTimeline;

    Log.d(current_module, "====发送请求给微信了======");

    boolean result = api.sendReq(req);

    Log.d(current_module, "====result======"+result);

    Activity activity = TiApplication.getInstance().getCurrentActivity();

    Log.d(current_module, activity.toString());

  }

参考的解决方案：

I solved this trouble. @Kroll.onAppCreate   public static void onAppCreate(TiApplication app)   {     Log.d(LCAT, "inside onAppCreate");     api = WXAPIFactory.createWXAPI(app,APP_ID,true);     api.registerApp(APP_ID);     Log.d(LCAT, "================= register App success=====================");   } 参考文档： IWXAPI 有状态信息appId，每次调用时都实例化一个新对象 ========== METHOD SUMMARY =========== Method Summary static IWXAPI createWXAPI(Context context, java.lang.String appId)              static IWXAPI createWXAPI(Context context, java.lang.String appId, boolean checkSignature)              其实最主要的就是因为， 签名不对的问题。所以，一定要确保签名没有问题! 参考链接http://stackoverflow.com/questions/29075496/how-to-set-the-activity-in-titanium-when-i-send-message-to-wechat
