Cordova WebViewを埋め込む、受信者が登録されていません

Question

私はCordova WebvViewをプロジェクトのコンポーネントとして埋め込んでいます。戻るボタンを押すとLogCatに「Receiver Not Registered！」というエラーが表示されます。私は受信機を登録していないと思う。 GitHub hereのサンプルプロジェクトもあります。私もこのアプリケーションを実行すると同じエラーが発生します。

私がしたいことは、AndroidプロジェクトにCordova WebViewを埋め込み、いくつかのjavascript機能を実行することです。

ここは私の主な活動です。 EDIT

public class MainNativeViewController extends FragmentActivity implements CordovaInterface, 
    JavaScriptListener { 

FragmentTransaction transaction; 
RelativeLayout childBrowser;

    // 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(); 
    }

       .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(); 
    } 
} 
} 

：ここはLogCat出力です。

EDIT：

私は解決策になってしまいました。私はフラグメントでCordova Web Viewを使用していましたが、フラグメントから移動してフラグメントコンテナを使用して同じxmlに配置しました。今それはエラーなく動作します。 GitHubのサンプルプロジェクトでも同じですが、CordovaWebViewはFrameLayoutにあります。あなたが全体を実装する必要はありません

Answer 1

では、次を使用することができ、自分自身を流し破壊：

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

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

・ホープ、このことができます。

Answer 2

私は

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

    }
