Видеоклипът от YouTube не се възпроизвежда в WebView

Изглежда като дубликат на възпроизвеждане на видеоклип от YouTube в WebView и YouTube Video не се възпроизвежда в WebView - Android

За да го накарам да работи чрез WebView, използвах следните две стъпки (версия 4.2.2/Nexus 4):

1. На shouldOverrideUrlLoading добавих webview.setWebChromeClient(new WebChromeClient());

2. В AndroidManifest.xml за activity таг добавих android:hardwareAccelerated="true"

AndroidManifest.xml също трябва да съдържа разрешение за интернет.

Въпреки че точните стъпки с възпроизвеждане на видео чрез WebView могат да бъдат специфични за устройството и версията на Android, има и други алтернативи на WebView, като VideoView или използване на Youtube Android Player API.

РЕДАКТИРАНЕ1

Що се отнася до пауза и цял екран, това всъщност е втора връзка, която споменах в началото. За да го улесня, публикувам код, който работи на моя Nexus.

1. В activity_main.xml

   <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="@dimen/activity_vertical_margin"
       android:paddingLeft="@dimen/activity_horizontal_margin"
       android:paddingRight="@dimen/activity_horizontal_margin"
       android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >
   
   <FrameLayout
             android:id="@+id/fullscreen_custom_content"
             android:layout_width="match_parent"
             android:layout_height="match_parent"
             android:background="#FF000000"/>
   
   <LinearLayout 
             android:id="@+id/linearlayout"
             android:layout_width="fill_parent" 
             android:layout_height="fill_parent"> 
   
        <WebView
              android:id="@+id/webView"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent" />
   
   </LinearLayout>
   </RelativeLayout>
   

2. В клас MainActivity:

   public class MainActivity extends Activity {
   
   private WebView mWebView;  
   private LinearLayout mContentView;
   private FrameLayout mCustomViewContainer;
   private WebChromeClient.CustomViewCallback mCustomViewCallback;

       mWebView.setWebViewClient(new HelloWebViewClient());
   
   }
   
   @Override

       // Inflate the menu; this adds items to the action bar if it is present.
       getMenuInflater().inflate(R.menu.main, menu);
       return true;
   }
   
   
   
   private class HelloWebViewClient extends WebViewClient  {

       public boolean shouldOverrideUrlLoading(WebView webview, String url)
       {
           webview.setWebChromeClient(new WebChromeClient() {
   
               private View mCustomView;
   
                @Override
               public void onShowCustomView(View view, WebChromeClient.CustomViewCallback callback)
               {
                   // if a view already exists then immediately terminate the new one
                   if (mCustomView != null)
                   {
                       callback.onCustomViewHidden();
                       return;
                   }
   
                   // Add the custom view to its container.
                   mCustomViewContainer.addView(view, COVER_SCREEN_GRAVITY_CENTER);
                   mCustomView = view;
                   mCustomViewCallback = callback;
   
                   // hide main browser view
                   mContentView.setVisibility(View.GONE);
   
                   // Finally show the custom view container.
                   mCustomViewContainer.setVisibility(View.VISIBLE);
                   mCustomViewContainer.bringToFront();
               }
   
           }); 
   
         webview.loadUrl(url);
   
         return true;
       }
   }
   
   @Override
   public boolean onKeyDown(int keyCode, KeyEvent event)
   {
       if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack())
       {
           mWebView.goBack();
           return true;
       }
       return super.onKeyDown(keyCode, event);
   
   } 
   }

Добавянето на webchrome клиент решава проблема,

web = (WebView) vi.findViewById(R.id.offer_webView1);

        web.loadUrl(getResources().getString(R.string.videolink));

        web.getSettings().setJavaScriptEnabled(true);
        // web.getSettings().setDomStorageEnabled(true);

        web.getSettings().setAllowContentAccess(true);
        WebSettings webSettings = web.getSettings();
        webSettings.setPluginState(WebSettings.PluginState.ON);
        webSettings.setUseWideViewPort(true);
        webSettings.setLoadWithOverviewMode(true);
        web.canGoBack();
        web.setWebChromeClient(new WebChromeClient() {});
