video with iframe doesn't display on Android Webview

Question

I am working on Android project (API level 8) displaying WebView from another website which I cannot change the code of these website. I am having trouble with video clip in WebView on some devices that does not enable Force GPU rendering (in settings --> Developer options). The following codes are the codes that I read from the website

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

and

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

On Android side I already enable several settings which are

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

I believe I can't use android:hardwareAccelerated="true" since I am working on API level 8

When I turn off Force GPU rendering the error on logcat are shown as follows

Answer 1

Perhaps it's problem of hardware acceleration. Try to disable it :

@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);
    }
}
