Embedding Cordova WebView, Empfänger ist nicht registriert

Question

Ich habe die Cordova WebvView als Komponente in mein Projekt eingebettet, alles funktioniert gut außer einer Sache; Wenn die Zurück-Taste gedrückt wird, erhalte ich einen Fehler auf LogCat, der sagt "Empfänger nicht registriert!" Ich glaube nicht, dass ich einen Empfänger registriert habe. Es gibt auch ein Beispielprojekt auf GitHub here. Ich bekomme auch den gleichen Fehler, wenn ich diese Anwendung ausführen.

Was ich tun möchte, ist Cordova WebView in mein Android-Projekt einbetten und einige Javascript-Funktionen ausführen.

Hier ist meine Haupttätigkeit;

public class MainNativeViewController extends FragmentActivity implements CordovaInterface, 
    JavaScriptListener { 

FragmentTransaction transaction; 
RelativeLayout childBrowser; 
RelativeLayout dialogBox; 
RelativeLayout emailComposer; 

private ExecutorService threadPool; 

CordovaWebViewFragment cordovaWebViewFragment; 

public CordovaWebView cordovaWebView; 

public LayoutInflater inflater; 
CordovaPlugin mActivityResultCallback; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.fragment_container); 

    overridePendingTransition(R.anim.fade_in, R.anim.fade_out); 

    threadPool = Executors.newCachedThreadPool(); 

    cordovaWebView = SingleTonCordovaWebView.getCordovaWebView(this); 
    cordovaWebView.loadUrl("file:///android_asset/www/invoke_native_view.html"); 

    FragmentManager manager = getSupportFragmentManager(); 

    ListFragment listFragment = new ListFragment(); 

    manager.beginTransaction().add(R.id.fragment_container, listFragment).commit(); 
} 

@Override 
public void showFragment(String fragmentName) { 

    /* 
    * This method is used to create and replace a fragment to the 
    * container. according to name passed through here. 
    */ 

    transaction = getSupportFragmentManager().beginTransaction(); 
    transaction.setCustomAnimations(R.anim.slide_in_right, R.anim.slide_out_left, 
      R.anim.slide_in_left, R.anim.slide_out_right); 

    if (fragmentName.equals("error")) { 
     DialogCreator dialog = new DialogCreator(this); 
     dialog.createDialog("Error !", "Fragment Name is wrong,", "Check fragment name", false); 
    } else { 
     // fragment name is ignored for different cases, it will be used for 
     // further proporties. 
     // Just checking out the error in the case its not right parameter. 

     NativeViewTestFragment testFragment = new NativeViewTestFragment(fragmentName); 

     transaction.replace(R.id.fragment_container, testFragment); 
     transaction.addToBackStack(null); 
     transaction.commit(); 
    } 
} 

@Override 
protected void onNewIntent(final Intent intent) { 
    super.onNewIntent(intent); 

    // Forward to plugins 
    if ((this.cordovaWebView != null) && (this.cordovaWebView.pluginManager != null)) { 
     this.cordovaWebView.pluginManager.onNewIntent(intent); 
    } 
} 

@Override 
public void cancelLoadUrl() { 

} 

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

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

@Override 
public Context getContext() { 
    return this; 
} 

@Override 
public Object onMessage(final String id, final Object data) { 
    // return getCordovaFragment().onMessage(id, data); 
    return null; 
} 

@Override 
public void setActivityResultCallback(CordovaPlugin arg0) { 
    // TODO Auto-generated method stub 

} 

@Override 
public void startActivityForResult(CordovaPlugin plugin, Intent intent, int requestCode) { 
    mActivityResultCallback = plugin; 
    startActivityForResult(intent, requestCode); 
} 

@Override 
/** 
* Called when the system is about to start resuming a previous activity. 
*/ 
protected void onPause() { 
    super.onPause(); 

    // Send pause event to JavaScript 
    this.cordovaWebView.loadUrl("javascript:try{cordova.fireDocumentEvent('pause');}catch(e){console.log('exception firing pause event from native');};"); 

    // Forward to plugins 
    if (this.cordovaWebView.pluginManager != null) { 
     this.cordovaWebView.pluginManager.onPause(true); 
    } 
    threadPool.shutdown(); 
    threadPool = null; 
} 

@Override 
/** 
* Called when the activity will start interacting with the user. 
*/ 
protected void onResume() { 
    super.onResume(); 

    threadPool = Executors.newCachedThreadPool(); 

    if (this.cordovaWebView == null) { 
     return; 
    } 

    // Send resume event to JavaScript 
    this.cordovaWebView 
      .loadUrl("javascript:try{cordova.fireDocumentEvent('resume');}catch(e){console.log('exception firing resume event from native');};"); 

    // Forward to plugins 
    if (this.cordovaWebView.pluginManager != null) { 
     this.cordovaWebView.pluginManager.onResume(true); 
    }  
} 

@Override 
/** 
* The final call you receive before your activity is destroyed. 
*/ 
public void onDestroy() { 
    super.onDestroy(); 
    if (cordovaWebView.pluginManager != null) { 
     cordovaWebView.pluginManager.onDestroy(); 
    } 

    if (this.cordovaWebView != null) { 

     // Send destroy event to JavaScript 
     this.cordovaWebView 
       .loadUrl("javascript:try{cordova.require('cordova/channel').onDestroy.fire();}catch(e){console.log('exception firing destroy event from native');};"); 

     // Load blank page so that JavaScript onunload is called 
     this.cordovaWebView.loadUrl("about:blank"); 

     // Forward to plugins 
     if (this.cordovaWebView.pluginManager != null) { 
      this.cordovaWebView.pluginManager.onDestroy(); 
     } 
    } else { 
     // this.endActivity(); 
    } 
} 
}

EDIT:

landete ich mit einer Lösung auf. Ich benutzte Cordova Web View in einem Fragment, ich zog es aus dem Fragment und legte es in dasselbe XML mit Fragmentcontainer. Jetzt funktioniert es ohne Fehler. Es ist das gleiche im Beispielprojekt in der GitHub, CordovaWebView ist in FrameLayout.

Answer 1

Sie brauchen nicht das ganze zu implementieren zerstören selbst fließen, können Sie die folgende verwenden:

public void onDestroy() { 
    LOG.d("Destroying the View", "onDestroy()"); 
    super.onDestroy(); 

    if (this.cwv != null) { 
    this.cwv.handleDestroy(); 
    } 
} 

Hoffnung, das hilft.

Answer 2

Ich löste dies in meinem Fragment das durch Zugabe von folgenden onDestroyView()

@Override 
    public void onDestroyView() { 
     super.onDestroyView(); 
     mCordovaWebView.handleDestroy(); 

    }
