Your execute menthod is not quite right. When you do:
    return new PluginResult(PluginResult.Status.OK,resultFunction);

that effectively returns nothing as a result. Instead you need to do:

    PluginResult r = new PluginResult(PluginResult.Status.NO_RESULT);
    r.setKeepCallback(true);
    return r;

which will tell the JS layer that there is info coming soon. Then in
your onActivityResult method you need to call:

  this.success(new PluginResult(PluginResult.Status.OK, msg), this.callbackId);

and you should get your result correctly.

有问题的代码，参考上面修改

Hi,
i‘m trying to pass a value from my Android java plugin to javascript in index.html.
This is my code :

PluginWrapper.js
var PluginWrapper = function() {

};

PluginWrapper.prototype.crop = function (name, win, fail){

   console.log("Prima di execute!");

   return PhoneGap.exec(win,fail,"PluginWrapper","crop",[name]);

  };

PhoneGap.addConstructor(function() {

 PhoneGap.addPlugin(‘PluginWrapper‘,new PluginWrapper());

});

PluginWrapper.java

package it.Prova;



import org.json.JSONArray;

import com.phonegap.api.Plugin;

import com.phonegap.api.PluginResult;

import android.content.Intent;

import android.util.Log;



public class PluginWrapper extends Plugin{

    private String resultFunction = null;    

    @Override

    public PluginResult execute(String arg0, JSONArray arg1, String arg2) {

        Log.v("PLUGIN","PLUGIN EXECUTE");

        Start("");

        return new PluginResult(PluginResult.Status.OK,resultFunction);

    }

    public String Start(String name){

        Log.v("START","START");

        Intent intent = new Intent(this.ctx,PluginActivity.class);

        this.ctx.startActivityForResult((Plugin) this, intent, 0);

        return "OK";

    }

    public void onActivityResult(int requestCode, int resultCode, Intent intent) {

        super.onActivityResult(requestCode, resultCode, intent);

        if (requestCode == 0){

            String msg = intent.getStringExtra("returnedData");

            Log.v("FLAG","IN WRAPPER " + msg);

            resultFunction = msg;

        }

    }

}

PluginActivity.java

package it.Prova;

import android.app.Activity;

import android.content.Context;

import android.content.Intent;

import android.os.Bundle;

import android.widget.Button;

import android.util.Log;

import android.view.View;

import android.view.View.OnClickListener;



public class PluginActivity extends Activity{

    private Button btn;

    private int flag = 0;

    private Intent intentNew = null;

    private Context context = this;

    

     @Override

        public void onCreate(Bundle savedInstanceState) {

            super.onCreate(savedInstanceState);

            setContentView(R.layout.main);        

            intentNew = this.getIntent();

            btn = (Button) findViewById(R.id.button1);

            btn.setOnClickListener(new OnClickListener(){

                public void onClick(View v) {

                    flag = 1;

                    Log.v("FLAG","1 IN PLUGIN");

                                intentNew.putExtra("returnedData", Integer.toString(flag));

           if (getParent() == null) {
               setResult(RESULT_OK, intentNew);
           }
           else {    
               getParent().setResult(RESULT_OK, intentNew);
           }
           finish();
                       }                
                    });

     }

}

继承CordovaPluging的代码,Pluging继承CordovaPluging

public class WXPayPlugin extends CordovaPlugin {

    public static final String ACTION = "call";  
    private CallbackContext _callbackContext=null;
  
    @Override
