I am trying to show a YouTube clip embedded in a WebView in Android, with a web view size up to 640x360 pixels and in the center of the tablet screen. I managed to do this, however the YouTube clip seems to be disabled and a white background is displayed as shown in the screenshot below:
Here is the Java code:
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class VideoWebViewActivity extends Activity {
private static final int VIDEO_WIDTH = 640;
private static final int VIDEO_HEIGHT = 360;
private WebView webView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webView = (WebView) findViewById(R.id.weblink_webview);
webView.getSettings().setPluginsEnabled(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebChromeClient(new WebChromeClient());
webView.setWebViewClient(new WebViewClient() {
@Override
public void onReceivedError(final WebView view, final int errorCode, final String description, final String failingUrl) {
}
@Override
public boolean shouldOverrideUrlLoading(final WebView view, final String url) {
view.loadUrl(url);
return true;
}
@Override
public void onLoadResource(WebView view, String url) {
super.onLoadResource(view, url);
}
@Override
public void onPageFinished(WebView view, String url) {
}
});
String youtubeUrl = "http://www.youtube.com/embed/O1N2rENXq_Y";
String embedCode = "<!DOCTYPE html><html><head>" + " <style type=\"text/css\"> body { background-color: transparent; padding:0; margin:0; }</style>"
+ "</head><body><div align=\"center\"><iframe align=\"middle\" width=\"" + (VIDEO_WIDTH) + "\" height=\""
+ (VIDEO_HEIGHT) + "\" src=\"" + youtubeUrl
+ "\" frameborder=\"0\" allowfullscreen></iframe></div></body></html>";
webView.loadData(embedCode, "text/html", null);
}
@Override
public void onDestroy() {
if (webView != null) {
webView.destroy();
}
super.onDestroy();
}
}
And here is the xml layout:
<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/weblink"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:visibility="visible" >
<WebView
android:id="@+id/weblink_webview"
android:layout_width="640dip"
android:layout_height="wrap_content"
/>
</RelativeLayout>
Edit: The strangest thing about this is that it works great on a 7-inch tablet with Android 3.2, but on a 10-inch tablet with 4.0.3 (ICS) it looks like a screenshot. 10 inch tablet with a honeycomb 3.1. This makes me think that there is some parameter / problem causing the behavior in the web view itself.
