Answer 1

Here is the complete steps to start an activity from a cordova plugin

1. Install Plugman to create plugin

npm install -g plugman

2. Create cordova plugin using plugman

plugman create --name PluginName --plugin_id com.example.sample.plugin --plugin_version 0.0.1

N.B : plugin id never start with Uppercase

Now PluginName directory will be created. Plugin structure will be

PluginName/

|- plugin.xml

|- src/

|- www/PluginName.js

3. Add android platform to plugin

plugman platform add --platform_name android

Now plugin structure will be

PluginName/

|- plugin.xml

|- src/android/PluginName.java

|- www/PluginName.js

4. Now create a java file named NewActivity.java in src/android directory

This activity will be shown using our plugin.

NewActivity.java

package com.example.sample.plugin;

import android.app.Activity;
import android.os.Bundle;

public class NewActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        String package_name = getApplication().getPackageName();
        setContentView(getApplication().getResources().getIdentifier("activity_new", "layout", package_name));
    }
}

5. Now create layout file activity_new.xml in src/android directory

This is the layout file for our new activity

activity_new.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="16dp"
    android:paddingLeft="16dp"
    android:paddingRight="16dp"
    android:paddingTop="16dp"
    tools:context="com.example.sample.plugin.NewActivity">

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="New Activity"
        android:id="@+id/textView"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_marginTop="77dp" />
</RelativeLayout>

6. Now edit PluginName.java in src/android

Now we need to handle the request and start our new activity.

PluginName.java

package com.example.sample.plugin;

import android.content.Context;
import android.content.Intent;

import org.apache.cordova.CordovaPlugin;
import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaWebView;
import org.apache.cordova.CordovaInterface;

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

public class PluginName extends CordovaPlugin {

    public void initialize(CordovaInterface cordova, CordovaWebView webView) {
        super.initialize(cordova, webView);
    }

    @Override
    public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
        Context context = cordova.getActivity().getApplicationContext();
        if(action.equals("new_activity")) {
            this.openNewActivity(context);
            return true;
        }
        return false;
    }

    private void openNewActivity(Context context) {
        Intent intent = new Intent(context, NewActivity.class);
        this.cordova.getActivity().startActivity(intent);
    }
}

7. Now edit PluginName.js in www directory

Now create new method to call to start our new activity.

var exec = require('cordova/exec');

function plugin() {

}

plugin.prototype.new_activity = function() {
    exec(function(res){}, function(err){}, "PluginName", "new_activity", []);
}

module.exports = new plugin();

8. Now edit plugin.xml

Now we need to specify our files to plugin and make necessary changes in cordova AndroidManifest.xml file

plugin.xml

<?xml version='1.0' encoding='utf-8'?>
<plugin id="com.example.sample.plugin" version="0.0.1" xmlns="http://apache.org/cordova/ns/plugins/1.0" xmlns:android="http://schemas.android.com/apk/res/android">
    <name>PluginName</name>
    <js-module name="PluginName" src="www/PluginName.js">
        <clobbers target="PluginName" />
    </js-module>
    <platform name="android">
        <config-file parent="/*" target="res/xml/config.xml">
            <feature name="PluginName">
                <param name="android-package" value="com.example.sample.plugin.PluginName" />
            </feature>
        </config-file>
        <config-file target="AndroidManifest.xml" parent="/manifest/application">
            <activity android:label="New Activity" android:name="com.example.sample.plugin.NewActivity"></activity>
        </config-file>
        <config-file parent="/*" target="AndroidManifest.xml"></config-file>
        <source-file src="src/android/PluginName.java" target-dir="src/com/example/sample/plugin" />
        <source-file src="src/android/NewActivity.java" target-dir="src/com/example/sample/plugin" />
        <source-file src="src/android/activity_new.xml" target-dir="res/layout"/>
    </platform>
</plugin>

9. Now create a cordova project

cordova create CordovaProject com.example.sample.cordovaproject "Cordova App"

10. Add android platform to your cordova project

cordova platform add android

11. Now add your plugin

cordova plugin add your-plugin-local-path
eg: cordova plugin add "C:\PluginName"

12. Add a button to index.html in www directory

index.html

<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *">
        <meta name="format-detection" content="telephone=no">
        <meta name="msapplication-tap-highlight" content="no">
        <meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width">
        <link rel="stylesheet" type="text/css" href="css/index.css">
        <title>Hello World</title>
    </head>
    <body>
        <div class="app">
            <h1>Apache Cordova</h1>
            <div id="deviceready" class="blink">
                <p class="event listening">Connecting to Device</p>
                <p class="event received">Device is Ready</p>
            </div>
            <button id = "new_activity">New Activity</button>
        </div>
        <script type="text/javascript" src="cordova.js"></script>
        <script type="text/javascript" src="js/index.js"></script>
    </body>
</html>

13. Add click handler for new button in index.js in www/js directory

When our button is clicked, we will call our plugin method to start our new activity

index.js

var app = {
    initialize: function() {
        this.bindEvents();
    },
    bindEvents: function() {
        document.addEventListener('deviceready', this.onDeviceReady, false);
    },
    onDeviceReady: function() {
        app.receivedEvent('deviceready');
    },
    receivedEvent: function(id) {
        var parentElement = document.getElementById(id);
        var listeningElement = parentElement.querySelector('.listening');
        var receivedElement = parentElement.querySelector('.received');

        listeningElement.setAttribute('style', 'display:none;');
        receivedElement.setAttribute('style', 'display:block;');

        console.log('Received Event: ' + id);
        document.getElementById("new_activity").addEventListener("click", new_activity);
    }
};

app.initialize();

function new_activity() {
    PluginName.new_activity();
}

14. Now run this app in android phone

cordova run android

If all these steps are success and when we click New Activity button, our new activity will show up.

Answer 2

Hi you can use this plugin

cordova plugin add sevensky-cordova-plugin-intent

Usage :

    document.getElementById("btn_device_name").addEventListener("click", test);

    function test() {
        var obj = new Object();
        obj.name = "Ahmad"; //bundle string extra 1 string
        obj.family = "Aghazadeh"; //bundle string extra 2
        intentPlugin.startActivity("com.sevensky.test", "TestActivity", JSON.stringify(obj));
    }
