Cordova 是否有自动将 onActivityResult 传递给它的 CordovaPlugin 类的方法？

这是我当前的文件，手动执行:

package com.myapp;

import android.os.Bundle;
import org.apache.cordova.*;

import android.content.Intent;

import com.flyingsoftgames.googleplaytoken.GooglePlayToken;

public class MyApp extends CordovaActivity {

 @Override protected void onActivityResult (int requestCode, int resultCode, Intent data) {
  GooglePlayToken.runOnActivityResult (requestCode, resultCode, data);
 }

 @Override public void onCreate (Bundle savedInstanceState) {
  super.onCreate (savedInstanceState);
  super.init ();
  super.loadUrl(Config.getStartUrl());
 }
}

我尝试使用与 https://github.com/apache/cordova-plugin-camera/blob/master/src/android/CameraLauncher.java 中使用的相同技术让数据“自动”通过——但它崩溃了。这是目标类的工作(手动和无数据传递)和非工作(自动数据传递)版本。先工作，然后不工作。

工作，没有数据传递:

最佳答案

事实证明，我需要做的就是在 cordova.getActivity().startActivityForResult (intent, REQUEST_CODE_PICK_ACCOUNT); 之前运行 cordova.setActivityResultCallback (this);。
