Full screen option not available when loading YouTube video in WebView

Question

I have work so many time with the webview with in Android app. But this time I got strange issue with loading YouTube video in to WebView.

See, this is the screen shot of YouTube video loaded in Chrome browser, which have full screen option in it.

Now, below is the screen shot of my app in which I have loaded same video in webview. But it is not having that full screen option.

You can see the changes in both the images. Both the screen shots are taken from same device. But still it looks different.

My code for webView loading is in this pasteboard.

Update

I have also seen that the same issue is reported here. But don't know whether is there solution for that available or not.

Solution 1

iFrame is an option but you can try this

Android's WebView and WebChromeClient class extensions that enable fully working HTML5 video support

VideoEnabledWebView

I have not try this yet but hope will help to you.

Solution 2

Do following changes in your java file:

view.setWebViewClient(new Browser());
view.setWebChromeClient(new MyWebClient());

---

and add this 2 class that is class Browser and class MyWebClient in java file

class Browser
        extends WebViewClient
{
    Browser() {}

    public boolean shouldOverrideUrlLoading(WebView paramWebView, String paramString)
    {
        paramWebView.loadUrl(paramString);
        return true;
    }
}

public class MyWebClient
        extends WebChromeClient
{
    private View mCustomView;
    private WebChromeClient.CustomViewCallback mCustomViewCallback;
    protected FrameLayout mFullscreenContainer;
    private int mOriginalOrientation;
    private int mOriginalSystemUiVisibility;

    public MyWebClient() {}

    public Bitmap getDefaultVideoPoster()
    {
        if (MainActivity.this == null) {
            return null;
        }
        return BitmapFactory.decodeResource(MainActivity.this.getApplicationContext().getResources(), 2130837573);
    }

    public void onHideCustomView()
    {
        ((FrameLayout)MainActivity.this.getWindow().getDecorView()).removeView(this.mCustomView);
        this.mCustomView = null;
        MainActivity.this.getWindow().getDecorView().setSystemUiVisibility(this.mOriginalSystemUiVisibility);
        MainActivity.this.setRequestedOrientation(this.mOriginalOrientation);
        this.mCustomViewCallback.onCustomViewHidden();
        this.mCustomViewCallback = null;
    }

    public void onShowCustomView(View paramView, WebChromeClient.CustomViewCallback paramCustomViewCallback)
    {
        if (this.mCustomView != null)
        {
            onHideCustomView();
            return;
        }
        this.mCustomView = paramView;
        this.mOriginalSystemUiVisibility = MainActivity.this.getWindow().getDecorView().getSystemUiVisibility();
        this.mOriginalOrientation = MainActivity.this.getRequestedOrientation();
        this.mCustomViewCallback = paramCustomViewCallback;
        ((FrameLayout)MainActivity.this.getWindow().getDecorView()).addView(this.mCustomView, new FrameLayout.LayoutParams(-1, -1));
        MainActivity.this.getWindow().getDecorView().setSystemUiVisibility(3846);
    }
}

Solution 3

If I understand correctly you have an iframe that contains a second iframe (the youtube one). Try adding the allowfullscreen attribute to the "parent" iframe.

For full browser support it should look like this:

<iframe src="your_page_url" allowfullscreen="allowfullscreen" mozallowfullscreen="mozallowfullscreen" msallowfullscreen="msallowfullscreen" oallowfullscreen="oallowfullscreen" webkitallowfullscreen="webkitallowfullscreen"> </iframe>

class WebChrome(activity: Activity) : WebChromeClient() {

    private val activityRef = WeakReference(activity)

    private var customView: View? = null
    private var customViewCallback: CustomViewCallback? = null

    private var originalOrientation = 0
    private var originalSystemUiVisibility = 0

    override fun onProgressChanged(view: WebView, progress: Int) {
        view.context.activityCallback<MainActivity> {
            onProgress(progress)
        }
    }

    override fun getDefaultVideoPoster(): Bitmap? {
        return activityRef.get()?.run {
            BitmapFactory.decodeResource(applicationContext.resources, 2130837573)

I am direct loading url in to webview. I am not appending any iframe tag in it. So if I append it, will it work ?

[Rohìt Jíndal]

yes. Please try or you can do one thing.append this parameter in youtube url ?allowfullscreen=true.

[Shreyash Mahajan]

I have try your way. I am loading video like this way but it is not loading video. mWebView.loadUrl("<iframe src=\"youtube.com/watch?v=zxyauCOc5gs\" allowfullscreen=\"allowfullscreen\" mozallowfullscreen=\"mozallowfullscreen\" msallowfullscreen=\"msallowfullscreen\" oallowfullscreen=\"oallowfullscreen\" webkitallowfullscreen=\"webkitallowfullscreen\"> </iframe>");

[Shreyash Mahajan]

I got error in logcat like below: Refusing to load invalid URL: %3Ciframe%20src%3D%27https://www.youtube.com/watch?v=zxyauCO‌​c5gs' allowfullscreen='allowfullscreen' mozallowfullscreen='mozallowfullscreen' msallowfullscreen='msallowfullscreen' oallowfullscreen='oallowfullscreen' webkitallowfullscreen='webkitallowfullscreen'> </iframe> 03

[WideFide]

Wonder why this answer didn't get any upvote but this actually works. Only one bug, 'actionBar' gets shifted downwards. Still figuring out for solution. Thanks for this answer btw

[Deepak Gupta]

Really made my Day ...was searching for something like this from last 10 days, thanks @M D

[M Tomczynski]

@WideFide have you found any solution for actionBar? I've got the same problem

[M Tomczynski]

Buggy but working solution. Did those id's really had to be noname?

[Rohit Singh]

@WideFide Can you tell me please where i need to add above two classes ? Is it in separate file ? If yes, then MainActivity is class ?

[SARATH V]

thanks, i've been searching for this solution 2 days. works fine. not found any action bar issue since i'm using custom theme for application.

[aslamhossin]

Why not this answer is correct. This works fine for me.

[Ghanshyam Nayma]

shouldOverrideUrlLoading() is deprecated now

[Micah Simmons]

On the Galaxy S8 although the video would play in fullscreen the video itself didn't take up the whole screen and the letter box margin areas where transparent so you could see the layout that was being covered by the video. To add the black letter box edges add this code to the onShowCustomView() method: mCustomView.setBackgroundColor(Color.BLACK)

[William T. Mallard]

Thank you so much for this! Plus, rotating the phone while playing will automatically go full screen and vice versa! It's like Christmas! I'm hoping Android gets some coal in their stockings for not making this part of the SDK.
