Reproduzindo vídeos do youtube sem problemas na visualização da Web
Eu estou construindo um aplicativo onde um usuário pode ver umYouTube vídeo e pode ver as imagens de qual link está vindo do servidor. JogarYouTube o valor da chave de incorporação de vídeo vem do servidor como
`<div id =" _ cvp_11204 "> <span> </ span> </ div> <script type =" text / javascript "> (função () {var a; a = novo XMLHttpRequest; a.onreadystatechange = função () {rs = a.readyState; if (4 == rs && 200 == a.status) {var = JSON.parse (a.responseText), b; para (b em c.payload) if (c.payload.hasOwnProperty ( b)) {var d = c.payload [b]; document.getElementById ("cvp"+ b) .innerHTML = d.view}}}; a.open (" GET ","http://dummyurl.com/media.ids=?11134 )) a.send ()}) (janela);
</script>`
e eu sou capaz de reproduzir o vídeo também, mas estou enfrentando poucos problemas em termos de desempenho.
1) algumas vezes a voz começa, mas o vídeo começa a aparecer depois de algum tempo.
2) Algum controle não aparece.
3) Como posso reproduzir o vídeo diretamente no modo de tela cheia? Atualmente para reproduzir o vídeo no modo de tela cheia eu tenho que clicar no controle max para reproduzi-lo.
Como é a classe de atividade para webview
public class MainActivity extends Activity {
protected FrameLayout webViewPlaceholder;
protected WebView webView;
private FrameLayout mContentView;
private MyWebChromeClient mWebChromeClient = null;
private View mCustomView;
private FrameLayout mCustomViewContainer;
private WebChromeClient.CustomViewCallback mCustomViewCallback;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
System.out.println("Oncreate is getting called ---------------------------");
// Initialize the UI
if(savedInstanceState == null){
initUI();
}
}
protected void initUI()
{
// Retrieve UI elements
webViewPlaceholder = ((FrameLayout)findViewById(R.id.webViewPlaceholder));
mContentView = webViewPlaceholder;
// Initialize the WebView if necessary
if (webView == null)
{
System.out.println("webView == null -----------------------------------");
// Create the webview
webView = new WebView(this);
webView.setLayoutParams(new ViewGroup.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));

// Attach the WebView to its placeholder
webViewPlaceholder.addView(webView);
}
private void loadWebView(final String url) {
String s = ReadFromfile("link.txt", MainActivity.this);
s = "<html><body>"+s+"</body></html>";
webView.loadDataWithBaseURL("",Html.fromHtml(s).toString(),"text/html", "UTF-8",null);

@Override

mContentView.setVisibility(View.GONE);
mCustomViewContainer = new FrameLayout(MainActivity.this);

// Sometimes getting remove view first it parent excepetion on moto devices

E no manifesto também eu defini ohardwareaccelarated = true. aqui está o vídeo quando começa com controles
e aqui quando eu clico em maximizar o botão de vídeo fica em tela cheia que eu quero sem clicar no botão max, mas o vídeo deve jogar diretamente no modo de tela cheia.
Então, principalmente, como eu posso acelerar e aumentar o desempenho do meuWebView?
