How to implement phonegap/cordova in android webview?

Question

I need just a few minutes for someone to tell me if these steps are correct for implementing cordova in a android webview:

EDIT: Ok I finally got it working these are the right steps:

1. I create project: cordova create hello com.example.hello HelloWorld and enter the folder

2. cordova platform add android, cordova run android (cordova.jar is created) => the app is launched => device is ready is shown

3. I create a cordova_layout.xml in "/res/layout" with this code:

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" > 
    
    <org.apache.cordova.CordovaWebView 
        android:id="@+id/cordova_web_view" 
        android:layout_width="fill_parent" 
        android:layout_height="fill_parent" 
        android:layout_weight="1" />

</LinearLayout>

4. Import the project (as an "existing project" in eclipse) and add to the main java file after imports:

   public class HelloWorld extends Activity implements CordovaInterface {

   private CordovaWebView cordova_webview; private String TAG = "CORDOVA_ACTIVITY"; private final ExecutorService threadPool = Executors.newCachedThreadPool();

   @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.cordova_layout); cordova_webview = (CordovaWebView) findViewById(R.id.cordova_web_view); // Config.init(this); String url = "file:///android_asset/www/index.html"; cordova_webview.loadUrl(url, 10000); }

    @Override 
    protected void onPause() { 
        super.onPause(); 
        Log.d(TAG, "onPause");
    } 
   
   
    @Override 
    protected void onResume() { 
        super.onResume(); 
        Log.d(TAG, "onResume");
    } 
   
   
    @Override 
    protected void onDestroy() { 
        super.onDestroy(); 
        if (this.cordova_webview != null) {
            this.cordova_webview
                    .loadUrl("javascript:try{cordova.require('cordova/channel').onDestroy.fire();}catch(e){console.log('exception firing destroy event from native');};"); 
            this.cordova_webview.loadUrl("about:blank");
            cordova_webview.handleDestroy();
        } 
    } 
   
   
   
    @Override 
    public Activity getActivity() {
        return this;
    } 
   
   
    @Override 
    public ExecutorService getThreadPool() {
        return threadPool;
    } 
   
   
    @Override 
    public Object onMessage(String message, Object obj) {
        Log.d(TAG, message);
        if (message.equalsIgnoreCase("exit")) {
            super.finish(); 
        } 
        return null; 
    } 
   
   
    @Override 
    public void setActivityResultCallback(CordovaPlugin cordovaPlugin) {
        Log.d(TAG, "setActivityResultCallback is unimplemented");
    } 
   
   
    @Override 
    public void startActivityForResult(CordovaPlugin cordovaPlugin,
            Intent intent, int resultCode) {
        Log.d(TAG, "startActivityForResult is unimplemented");
    } 
   

   }

NOTE: the activity name must match the one in manifest.xml

Hope it will help you. Have a nice day!

If you want to load an url in a phonegap app then you may use the below code to load your first url from asset

public class MyPhoneGapActivity extends DroidGap {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    super.loadUrl("file:///android_asset/www/index.html", 10000);
}

For embedding a cordova webview in native android application and loading an url use the below code

public class CordovaActivity extends Activity implements CordovaInterface {

            private CordovaWebView cordova_webview;
            private String TAG = "CORDOVA_ACTIVITY";
            private final ExecutorService threadPool = Executors.newCachedThreadPool();


            @Override 
            protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.cordova_layout);
                cordova_webview = (CordovaWebView) findViewById(R.id.cordova_web_view);
                // Config.init(this); 
                String url = "file:///android_asset/www/index.html";
                cordova_webview.loadUrl(url, 10000);
            } 


            @Override 
            protected void onPause() { 
                super.onPause(); 
                Log.d(TAG, "onPause");
            } 


            @Override 
            protected void onResume() { 
                super.onResume(); 
                Log.d(TAG, "onResume");
            } 


            @Override 
            protected void onDestroy() { 
                super.onDestroy(); 
                if (this.cordova_webview != null) {
                    this.cordova_webview
                            .loadUrl("javascript:try{cordova.require('cordova/channel').onDestroy.fire();}catch(e){console.log('exception firing destroy event from native');};"); 
                    this.cordova_webview.loadUrl("about:blank");
                    cordova_webview.handleDestroy();
                } 
            } 



            @Override 
            public Activity getActivity() {
                return this;
            } 


            @Override 
            public ExecutorService getThreadPool() {
                return threadPool;
            } 


            @Override 
            public Object onMessage(String message, Object obj) {
                Log.d(TAG, message);
                if (message.equalsIgnoreCase("exit")) {
                    super.finish(); 
                } 
                return null; 
            } 


            @Override 
            public void setActivityResultCallback(CordovaPlugin cordovaPlugin) {
                Log.d(TAG, "setActivityResultCallback is unimplemented");
            } 


            @Override 
            public void startActivityForResult(CordovaPlugin cordovaPlugin,
                    Intent intent, int resultCode) {
                Log.d(TAG, "startActivityForResult is unimplemented");
            } 
}
