START ACTIVITY FOR RESULT

FIRST CLASS:



public class HelloWorld extends Activity {
/** Called when the activity is first created. */
String s;
TextView t;


@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
t = (TextView) findViewById(R.id.TextView01);
Button button = (Button) findViewById(R.id.Button01);
button.setOnClickListener(new OnClickListener() {


public void onClick(View v) {
Intent intent = new Intent(HelloWorld.this,
SecondActivity.class);
startActivityForResult(intent, 0);


}


});
}


@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
String s = data.getStringExtra("name");
t.setText(s);


}


}
SECOND CLASS:



public class SecondActivity extends Activity {
EditText te;
String s;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.second);
   //TextView te=(TextView)findViewById(R.id.TextView01);
  te=(EditText)findViewById(R.id.EditText01);
  Button  b=(Button)findViewById(R.id.Button01);
  b.setOnClickListener(new OnClickListener() {


public void onClick(View v) {
s=te.getText().toString();
Intent intent = new Intent();
intent.putExtra("name", s);
setResult(RESULT_OK, intent);
finish();

}


});
  
}
}

PASS THE VALUE ONE ACTIVITY TO ANOTHER

 FIRST CLASS:


           b.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
s=te.getText().toString();
                Intent intent = new Intent(First.this,Second.class);
        intent.putExtra("name", s);
StartActivity(intent);

}


});



SECONT CLASS:


    Bundle o=getintent().getExtras();
    String s=o.getString("name");

Getting an Access the java class method through the phonegap

From the PhoneGap download earlier, we need the following two files:

1. Android/phonegap-1.0.0.jar
2. Android/phonegap-1.0.0.js

In the root directory of the project you created in Eclipse, create two new directories:

1. /libs
2. /assets /www

Now copy

1. Android/phonegap-1.0.0.jar to /libs 
2. Android/phonegap-1.0.0.js  to /assets/www

In Eclipse, select the project in the Package Explorer and refresh (F5) the project. The copied file will appear in the project.

Now, create index.html in your www folder and add some code like so:

<!DOCTYPE HTML>

<html>

  <head>

    <meta name="viewport" content="width=320; user-scalable=no" />

    <meta http-equiv="Content-type" content="text/html; charset=utf-8">

    <title>PhoneGap</title>

 <link rel="stylesheet" href="master.css" type="text/css" media="screen" title="no title" charset="utf-8">

 <script type="text/javascript" charset="utf-8" src="phonegap-1.0.0rc2.js"></script>

 <script type="text/javascript" charset="utf-8" src="phonegap-toast.js"></script>

 <script type="text/javascript">

var ready = function() {

   var win = function () {      

     //console.log("registered ");

   },

    fail = function() {

     alert('Fail');

   };

   navigator.toast.showLong('bar');      

 };

 

  document.addEventListener('deviceready', ready, false);  

 </script>

  </head>

  <body>

    <button onclick="navigator.toast.cancel();">cancel</button>

  </body>

</html>

(i)add master.css in the same folder asset/www/

(ii)add two more file in the same directory

       *phonegap-1.0.0rc2.js

       *phonegap-toast.js

Create two java class in the src/

1.> com.chariotsolutions/Toastify

package com.chariotsolutions;

import com.phonegap.*;

import android.os.Bundle;

public class Toastify extends DroidGap {

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        super.loadUrl("file:///android_asset/www/index.html");

    }

}

2.> com.chariotsolutions.toast.plugin/ToastPlugin

package com.chariotsolutions.toast.plugin;

import android.util.Log;

import android.widget.Toast;

import com.phonegap.api.Plugin;

import com.phonegap.api.PluginResult;

import com.phonegap.api.PluginResult.Status;

import org.json.JSONArray;

import org.json.JSONException;

public class ToastPlugin extends Plugin {

    private static final String TAG = "ToastPlugin";

    private static final String LONG_TOAST_ACTION = "show_long";

    private static final String CANCEL_ACTION = "cancel";

    private static final int TOAST_MESSAGE_INDEX = 0;

    private Toast toast = null;

    private String toastMessage;

    @Override

    public PluginResult execute(String pluginAction, JSONArray data, String callbackId) {

        Log.d(TAG, pluginAction);

        if (pluginAction.equals(CANCEL_ACTION)) {

            this.ctx.runOnUiThread(new Runnable() {

                @Override

                public void run() {

                    if (toast != null) toast.cancel();

                }

            });

        } else {

            try {

                toastMessage = data.getString(TOAST_MESSAGE_INDEX);

                

            } catch (JSONException e) {

                Log.e(TAG, "Required parameter 'Toast Message' missing");

                return new PluginResult(Status.ERROR);

            }

            if (pluginAction.equals(LONG_TOAST_ACTION)) {

                Log.d(TAG, "long?");

                this.ctx.runOnUiThread(new Runnable() {

                    @Override

                    public void run() {

                        toast = Toast.makeText(ctx, toastMessage, Toast.LENGTH_LONG);

                        toast.show();

                    }

                });

            } else {

                this.ctx.runOnUiThread(new Runnable() {

                    @Override

                    public void run() {

                        toast = Toast.makeText(ctx, toastMessage, Toast.LENGTH_SHORT);

                        toast.show();

                    }

                });

            }

        }

        return new PluginResult(Status.OK);

    }

}

Finaly add the some code in Android Manifest file like

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

      package="com.chariotsolutions"
