WebView et HTML5 <video>

Après de longues recherches, j'ai eu cette chose à travailler. Voir le code suivant:

Test.java

import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;

public class Test extends Activity {

    HTML5WebView mWebView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mWebView = new HTML5WebView(this);

        if (savedInstanceState != null) {
            mWebView.restoreState(savedInstanceState);
        } else {    
            mWebView.loadUrl("http://192.168.1.18/xxxxxxxxxxxxxxxx/");
        }

        setContentView(mWebView.getLayout());
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        mWebView.saveState(outState);
    }

    @Override
    public void onStop() {
        super.onStop();
        mWebView.stopLoading();
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {

        if (keyCode == KeyEvent.KEYCODE_BACK) {
            if (mWebView.inCustomView()) {
                mWebView.hideCustomView();
            // mWebView.goBack();
                //mWebView.goBack();
                return true;
            }

        }
        return super.onKeyDown(keyCode, event);
    }
}

Attend reste des choses que vous pouvez comprendre.

En fait, il semble suffisant de simplement attacher un stock WebChromeClient à la vue du client, ala

mWebView.setWebChromeClient(new WebChromeClient());

et vous avez besoin d'avoir de l'accélération matérielle activée!

Au moins, si vous n'avez pas besoin de lire une vidéo en plein écran, il n'y a pas besoin de tirer sur le VideoView de la WebView et le pousser dans l'Activité de la vue. Il va jouer dans la vidéo de l'élément attribué rect.

Des idées comment intercepter la vidéo expand bouton?

Cette approche fonctionne très bien jusqu'à 2.3
Et en ajoutant hardwareaccelerated=true il fonctionne même de 3,0 à ICS
Un problème je suis confronté actuellement est lors de la deuxième lancement de l'application de lecteur multimédia est d'obtenir écrasé parce que je n'ai pas arrêté la lecture, et publié Media player.
Comme VideoSurfaceView objet, ce qui nous recevons dans onShowCustomView fonction depuis la version 3.0 de l'OS, sont spécifiques au navigateur et non pas un VideoView objet que dans, jusqu'à 2.3 OS
Comment puis-je y accéder et stopPlayback et de libérer des ressources?

Je sais que c'est une très vieille question, mais avez-vous essayé le hardwareAccelerated="true" manifeste drapeau de votre application ou de l'activité?

Avec cet ensemble, il semble fonctionner sans WebChromeClient modification (qui je peut attendre d'un DOM-Élément.)

Cette question est ans, mais peut-être que ma réponse sera aider les gens comme moi qui ont à supporter les anciennes version d'Android. J'ai essayé beaucoup de différentes approches qui ont travaillé sur certaines versions d'Android, mais pas sur tous. La meilleure solution que j'ai trouvé est d'utiliser le Tableau De Concordance De L'Webview qui est optimisé pour HTML5 support de la fonction et fonctionne sur Android 4.1 et supérieur. Il est aussi simple à utiliser que la valeur par défaut d'Android WebView. Il suffit d'inclure la bibliothèque. Ici vous pouvez trouver un tutoriel sur la façon de l'utiliser: https://diego.org/2015/01/07/embedding-crosswalk-in-android-studio/

Sur nid d'utilisation hardwareaccelerated=true et pluginstate.on_demand semble fonctionner
