videos - Reproducción de video HTML5 en pantalla completa en la vista web de Android
video html5 android (7)
Editar 2014/10: por demanda popular estoy manteniendo y moviendo esto a GitHub. Verifique cprcrack/VideoEnabledWebView para la última versión. Mantendrá esta respuesta solo como referencia.
Edición 2014/01: uso mejorado de ejemplos para incluir las vistas nonVideoLayout, videoLayout y videoLoading, para aquellos usuarios que solicitan más código de ejemplo para una mejor comprensión.
Edición 2013/12: algunas correcciones de errores relacionadas con la compatibilidad de los dispositivos Sony Xperia, pero que de hecho afectaron a todos los dispositivos.
Editar 2013/11: después del lanzamiento de Android 4.4 KitKat (nivel de API 19) con su nueva vista web de Chromium, tuve que trabajar duro nuevamente. Se hicieron varias mejoras. Debes actualizar a esta nueva versión. Libero esta fuente bajo WTFPL . Se aceptan donaciones (encuentre el enlace Donar en la parte inferior).
Editar 2013/04: después de 1 semana de arduo trabajo, finalmente logré todo lo que necesitaba. Creo que estas dos clases genéricas que he creado pueden resolver todos tus problemas.
VideoEnabledWebChromeClient se puede usar solo si no necesita la funcionalidad que VideoEnabledWebView agrega. Pero VideoEnabledWebView siempre debe confiar en VideoEnabledWebChromeClient . Por favor, lea todos los comentarios de las dos clases con cuidado.

/**
* This class serves as a WebChromeClient to be set to a WebView, allowing it to play video.
* Video will play differently depending on target API level (in-line, fullscreen, or both).
*
* It has been tested with the following video classes:
* - android.widget.VideoView (typically API level <11)
* - android.webkit.HTML5VideoFullScreen$VideoSurfaceView/VideoTextureView (typically API level 11-18)
* - com.android.org.chromium.content.browser.ContentVideoView$VideoSurfaceView (typically API level 19+)
*
* Important notes:
* - For API level 11+, android:hardwareAccelerated="true" must be set in the application manifest.
* - The invoking activity must call VideoEnabledWebChromeClient''s onBackPressed() inside of its own onBackPressed().
* - Tested in Android API levels 8-19. Only tested on http://m.youtube.com.

Bueno, he estado buscando hace unos días, cómo mostrar video HTML5 en modo de pantalla completa en Android WebView.
Logré reproducir videos HTML5 en mi vista web. Los problemas surgen cuando se muestra video en modo pantalla completa.
Como descubrí, Android tiene dos formas de manejar la etiqueta <video>:
En las versiones de Android <= 2.3.3 , se dispara el método onShowCustomView, y puedo tener la instancia de VideoView y configurar oyentes cuando finaliza el video, establecer controles, etc. Hasta ahora todo va bien.
En ICS (y probablemente 3.0 y superior) , parece que el <video> se maneja de manera diferente. Cuando se reproduce el video HTML5, no se llama a onShowCustomView en modo normal, parece que hay un negocio interno dentro del WebView que reproduce el video y se muestran todos los controles definidos en la etiqueta <video>. no puede acceder a ella de ninguna manera. En realidad, si el video se reproduce en modo normal, esto está bien porque los controles están ahí y están funcionando.
Eso me llevó al gran problema: cuando se muestra el video en modo de pantalla completa, se llama a onShowCustomView, pero en ICS, el parámetro "ver" no es una instancia de VideoView.
Me las arreglé para descubrir que la instancia es de VideoSurfaceView, una clase interna privada de clase HTML5VideoFullScreen. La única forma en que podemos acceder a esta clase interna es a través de la reflexión.
Después de mirar GrepCode para esta clase, aprendí que a diferencia de VideoView, HTML5VideoFullScreen $ VideoSurfaceView no contiene una instancia de MediaPlayer que puedo escuchar sus eventos o acceder a sus controles. Lo único que puedo hacer es tomar este VideoSurfaceView tal como está y ponerlo dentro de un diseño de pantalla completa sin controlarlo.
En pocas palabras: cuando visualizo video en pantalla completa, no sé cuándo termina el video, no se muestran sus controles, esto es bastante triste. No puedo obtener el disparador para cerrar la pantalla completa.
Intenté algunas soluciones fallidas:
Reflexión: Intenté llegar a la instancia HTML5VideoFullScreen, que contiene un miembro de MediaPlayer, desde la clase interna VideoSurfaceView. No logré obtenerlo, no estoy seguro de que esto sea posible (ViewSurfaceView no contiene la instancia de su propietario).
Regístrese para los eventos de video a través de Javascript (activado, por ejemplo) y maneje lo que necesito en JAVA a través de JavascriptInterface: Encontré que esta solución no es confiable porque al hacer esto me encontré con otro problema: la etiqueta <video> puede anidarse en un La fuente del iframe no es mía y no puedo obtener su contenido (getElementById o getElementsByTagName [i] son nulos), lo que significa que no puedo acceder al elemento <video> dentro del iframe.
Todavía estoy buscando una solución, se escribe muy poco sobre este tema. ¿Alguien logró resolverlo? ¡La ayuda sería muy apreciada!
Clase VideoView : Here (tiene MediaPlayer)
HTML5VideoFullScreen $ VideoSurfaceView class: Here (no tiene MediaPlayer)
Esto es genial. Pero si desea que los enlaces de su sitio web se abran en la propia aplicación, agregue este código en su ExampleActivity.java:
webView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().endsWith("yourwebsite.com")) {
return false;
}
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
});
La respuesta de Cprcrack funciona muy bien para los niveles API de 19 y menos. Solo una pequeña adición a cprcrack''s onShowCustomView hará funcionar en el nivel API 21+
if (Build.VERSION.SDK_INT >= 21) {
videoViewContainer.setBackgroundColor(Color.BLACK);
((ViewGroup) webView.getParent()).addView(videoViewContainer);
webView.scrollTo(0,0); // centers full screen view
} else {
activityNonVideoView.setVisibility(View.INVISIBLE);
ViewGroup.LayoutParams vg = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT);
activityVideoView.addView(videoViewContainer,vg);
activityVideoView.setVisibility(View.VISIBLE);
}
También deberá reflejar los cambios en onHideCustomView
Muchas gracias por esa clase, Cristian.
Hice un pequeño ajuste para que la vista de carga personalizada sea opcional, así:
@Override
public View getVideoLoadingProgressView() // Video will start loading, only called in the case of VideoView (typically API level 10-)
{
if (loadingView == null)
{
return super.getVideoLoadingProgressView();
}
else
{
loadingView.setVisibility(View.VISIBLE);
return loadingView;
}
}
También agregué un nuevo constructor que solo toma dos parámetros. De todos modos, solo una pequeña simplificación si no necesitas la vista de carga. Gracias de nuevo por proporcionar esto.
Parece que en lollipop y hasta (o tal vez solo una versión diferente de WebView) que llamar al cprcrack''s onHideCustomView() no funciona. Funciona si se llama desde el botón de pantalla completa de salida, pero cuando se llama específicamente al método, solo saldrá de pantalla completa, pero la vista webView queda en blanco. Una forma de onHideCustomView() es simplemente agregar estas líneas de código a onHideCustomView() :
String js = "javascript:";
js += "var _ytrp_html5_video = document.getElementsByTagName(''video'')[0];";
js += "_ytrp_html5_video.webkitExitFullscreen();";
webView.loadUrl(js);
Esto notificará a la vista web que se ha cerrado la pantalla completa.
Solo establece
mWebView.setWebChromeClient(new WebChromeClient());
y el video se reproduce como normalmente no necesita ninguna vista personalizada.
Editar: vea mi otra respuesta , ya que probablemente no la necesite ahora.
Como dijiste, en los niveles API 11+ se pasa HTML5VideoFullScreen $ VideoSurfaceView. Pero no creo que tengas razón cuando dices que "no tiene un MediaPlayer".
Esta es la forma de llegar a la instancia de MediaPlayer desde la instancia de HTML5VideoFullScreen $ VideoSurfaceView utilizando la reflexión :
@SuppressWarnings("rawtypes")
Class c1 = Class.forName("android.webkit.HTML5VideoFullScreen$VideoSurfaceView");
Field f1 = c1.getDeclaredField("this$0");
f1.setAccessible(true);
@SuppressWarnings("rawtypes")
Class c2 = f1.getType().getSuperclass();
Field f2 = c2.getDeclaredField("mPlayer");
f2.setAccessible(true);
Object ___html5VideoViewInstance = f1.get(focusedChild); // Look at the code in my other answer to this same question to see whats focusedChild
Object ___mpInstance = f2.get(___html5VideoViewInstance); // This is the MediaPlayer instance.
Entonces, ahora puede configurar el oyente onCompletion de la instancia de MediaPlayer de esta manera:
OnCompletionListener ocl = new OnCompletionListener()
{
@Override
public void onCompletion(MediaPlayer mp)
{
// Do stuff
}
};
Method m1 = f2.getType().getMethod("setOnCompletionListener", new Class[] { Class.forName("android.media.MediaPlayer$OnCompletionListener") });
m1.invoke(___mpInstance, ocl);
El código no falla, pero no estoy completamente seguro de si realmente se llamará al oyente onCompletion o si podría ser útil para su situación. Pero solo en caso de que alguien quiera probarlo.
