Android Webview app won't let video player go full screen

Hi I created a WebView app for my video site. The design of the site is a hybrid that loads for mobile users. Only videos compatible with mobile devices are loaded onto the hybrid. The players are from Vk, DailyMotion, YouTube, and QuickTime.

The videos only play on SDK 11 and higher but when I click on the player button to go full screen it only stops the video from playing while never launching into full screen mode.

(Webviewactivity.java)

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().requestFeature(Window.FEATURE_PROGRESS);
    setContentView(R.layout.main);

    parentView = (RelativeLayout) findViewById(R.id.parent_rl);

    webviewProgress = (ProgressBar) findViewById(R.id.webview_progress);

    webview = (WebView) findViewById(R.id.webview);
    webview.getSettings().setJavaScriptEnabled(true);
    webview.getSettings().setBuiltInZoomControls(true);
    webview.getSettings().setAllowFileAccess(true);
    webview.setWebViewClient(new MyWebViewClient());
    webview.getSettings().setPluginState(WebSettings.PluginState.ON);
    webview.loadUrl(URL);
    webviewProgress.setProgress(0);

    webview.setWebChromeClient(new MyWebChromeClient());
    webview.setDownloadListener(new DownloadListener() {
        public void onDownloadStart(String url, String userAgent,
                String contentDisposition, String mimetype,
                long contentLength) {
            mProgressDialog = new ProgressDialog(WebViewActivity.this);
            mProgressDialog.setMessage("Downloading...");
            mProgressDialog.setIndeterminate(false);
            mProgressDialog.setMax(100);
            mProgressDialog
                    .setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
            DownloadFile downloadFile = new DownloadFile();
            downloadFile.execute(url);
        }
    });

    initSlider();

    initAdmob();
}

/**
 * When when file was chosen
 */
@Override
protected void onActivityResult(int requestCode, int resultCode,
        Intent intent) {
    if (requestCode == FILECHOOSER_RESULTCODE) {
        if (null == mUploadMessage)
            return;
        Uri result = intent == null || resultCode != RESULT_OK ? null
                : intent.getData();
        mUploadMessage.onReceiveValue(result);
        mUploadMessage = null;

You need to implement showCustomView & hideCustomView method of WebChromeClient, also You need android:hardwareAccelerated="true" in your AndroidManifest File. I am posting my sample project here. What i have done is kept one Framelayout(customContainer) in my main.xml, and adding view received in showCustomView here, and removing it in onHide. Also hiding/showing webview accordingly. Below code works perfectly on device.

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.example.webview"
          android:versionCode="1"
          android:versionName="1.0">
    <uses-sdk android:minSdkVersion="8"/>
    <uses-permission android:name="android.permission.INTERNET"/>
    <application android:label="@string/app_name" android:icon="@drawable/ic_launcher"
            android:hardwareAccelerated="true">
        <activity android:name="MyActivity"
                  android:configChanges="orientation|keyboardHidden"
                  android:hardwareAccelerated="true"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>
</manifest>

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
        >
    <WebView
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:id="@+id/webView"
            android:layout_gravity="center"
            />
    <FrameLayout
            android:id="@+id/customViewContainer"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:visibility="gone"
            />
</LinearLayout>

              android:layout_centerInParent="true"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent">

    <ProgressBar android:id="@android:id/progress"
