    如果想要响应微信分享登录resp需要在mainActivity同级目录下创建wxapi文件夹 下面新建WXEntryACtivity集成Activity(需要在AndroidManifest.xml注册）

    <activity android:name=".wxapi.WXEntryActivity" android:exported="true" android:launchMode="singleTop"/>

    private IWXAPI api;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        api = WXAPIFactory.createWXAPI(this, "wxb25d3dec3db1affc", false);
        onNewIntent(getIntent());
        finish();
    }

        @Override
    public void onReq(BaseReq baseReq) {

    }

    @Override
    public void onResp(BaseResp baseResp) {
        sendBroadcastToWechat(baseResp);
    }

    private void sendBroadcastToWechat(BaseResp baseResp) {
        Intent intent = new Intent();
        intent.setAction("sendResp");
        if (baseResp instanceof SendAuth.Resp) {
            SendAuth.Resp resp = (SendAuth.Resp) (baseResp);
            intent.putExtra("code", resp.errCode == 0 ? resp.code : "-1");
            intent.putExtra("type", "SendAuthResp");
            sendBroadcast(intent);
        } else {
            intent.setAction("sendResp");
            intent.putExtra("code", baseResp.errCode + "");
            intent.putExtra("type", "ShareResp");
            sendBroadcast(intent);
        }
    }
    protected void onNewIntent(Intent intent) {
        api.handleIntent(intent, this);
    }

如果想要响应微信支付resp需要在mainActivity同级目录下创建wxapi文件夹(需要在AndroidManifest.xml注册）

<activity
  android:name=".wxapi.WXPayEntryActivity"
  android:exported="true"
  android:launchMode="singleTop">

  <intent-filter>
      <action android:name="android.intent.action.VIEW"/>
      <category android:name="android.intent.category.DEFAULT"/>
      <data android:scheme="your AppId"/>
  </intent-filter>
</activity>

     下面新建WXEntryACtivity集成Activity

public class WXPayEntryActivity extends Activity implements IWXAPIEventHandler {


   private IWXAPI api;

   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       api = WXAPIFactory.createWXAPI(this, "wxb25d3dec3db1affc", false);
       onNewIntent(getIntent());
       finish();
   }

   @Override
   public void onReq(BaseReq baseReq) {

   }

   @Override
   public void onResp(BaseResp baseResp) {
       sendBroadcastToWechat(baseResp);
   }

   private void sendBroadcastToWechat(BaseResp baseResp) {
       Intent intent = new Intent();
       intent.setAction("sendResp");
       intent.putExtra("code", baseResp.errCode + "");
       intent.putExtra("type", "PayResp");
       sendBroadcast(intent);
   }

   protected void onNewIntent(Intent intent) {
       api.handleIntent(intent, this);
   }


}

     postNotificationName:@"WeChat" object:nil userInfo:@{@"url":urlStr}];
    return YES;
}

// ios 9.0+
