Answer 1

To achieve this follows these steps :
1) Set WebChromeClient to your webview.
Exmaple : WebView.setWebChromeClient(new MyChromeBrowser());
2) Implement method onShowCustomView() and onHideCustomView() inside your WebChromeClient.
Example : `

private class MyChromeBrowser extends WebChromeClient {
    @Override
    public void onShowCustomView(View view, CustomViewCallback callback) {
        super.onShowCustomView(view, callback);
    }

    @Override
    public void onHideCustomView() {
        super.onHideCustomView();
    }
}`

3) Give android:hardwareAccelerated="true" in manifest file for your activity.
Example : <activity android:name=".MainActivity" android:hardwareAccelerated="true" />
Update :
To fix this try these :
change these lines : webView.setWebChromeClient(new MyWebChromeClient()); to

mWebChromeClient = new myWebChromeClient();
webView.setWebChromeClient(mWebChromeClient);

inside initWebView() method.

To let the system decide the best orientation in full-screen mode add this line to onShowCustomView(View view, CustomViewCallback callback) method:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
