video con iframe non visualizzato su Android Webview

Question

Sto lavorando su progetto Android (livello API 8) che visualizza WebView da un altro sito Web che non posso modificare il codice di questo sito Web. Ho problemi con il video clip in WebView su alcuni dispositivi che non abilitano il rendering Force GPU (nelle impostazioni -> Opzioni sviluppatore). I seguenti codici sono i codici che ho letto dal sito web

<center><iframe width=\"500\" height=\"315\" src=\"http:\/\/www.youtube.com\/embed\/bf7wpubnyIE\" frameborder=\"0\" allowfullscreen><\/iframe><\/center> <br \/> 

e

<center> <iframe frameborder=\"0\" width=\"480\" height=\"323\" src=\"http:\/\/www.dailymotion.com\/embed\/video\/xrmnk1\"><\/iframe> <\/center><br \/> 

Sul lato Android Ho già effettuato diverse impostazioni che sono

webview.setWebChromeClient(new WebChromeClient()); 
webview.setWebViewClient(new WebViewClient()); 
webview.getSettings().setJavaScriptEnabled(true); 
webview.getSettings().setPluginsEnabled(true); 

credo che non posso utilizzare android:hardwareAccelerated="true" poiché sto lavorando al livello API 8

Quando spengo la Forza GPU che mostra l'errore su logcat viene mostrato come segue

Answer 1

Forse è un problema di accelerazione hardware. Prova a disabilitarla:

@TargetApi(11) 
private void disableHardwareAcceleration() { 
    if(getCustomApp().isHarwareAccelerateDisable() && android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) { 
     Log.e(TAG, "disable HardwareAcceleration"); 
     webview.setLayerType(View.LAYER_TYPE_SOFTWARE, null); 
    } 
}
