How to stop youtube video playing in Android webview?

How can I stop a YouTube video which is played in my webview? When I click on the back button the video doesn't stop and instead continues in the background.

Code:

webView = (WebView) findViewById(R.id.webview); 
webView.getSettings().setPluginsEnabled(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setBuiltInZoomControls(false); 
webView.getSettings().setSupportZoom(false);
webView.loadData(myUrl,"text/html", "utf-8");

See the following post about WebView threads never stopping

Essentially you'll need to call the WebView's onPause method from your own Activity's onPause method.

The only trick with this is that you cannot call the WebView's onPause method directly because it is hidden. Therefore you will need to call it indirectly via reflection. The following code should get you started on setting up your own Activity's onPause method:

@Override
public void onPause() {
	super.onPause();
		
	try {
		Class.forName("android.webkit.WebView")
		    	.getMethod("onPause", (Class[]) null)
	    	    	    	.invoke(webview, (Object[]) null);
			
	} catch(ClassNotFoundException cnfe) {
		...
	} catch(NoSuchMethodException nsme) {
		...
	} catch(InvocationTargetException ite) {
		...
	} catch (IllegalAccessException iae) {
		...
	}
}

Note that the variable 'webview' in the try block above is a private instance variable for the class and is assigned to in the Activity's onCreate method.

Solution: 1 - After spending lot of time, I got the conclusion to pause the video which is playing with WebView <iframe> concept of HTML.

Just override the onPause() method on Activity or Fragment whereever you used WebView, and call it. It works for me.

@Override
public void onPause() {
	super.onPause();
	mWebView.onPause();
}

@Override
public void onResume() {
    super.onResume();
    mWebView.onResume();
}

Solution: 2 - If above solution doesn't work for you then you can force WebView to load a non existent html file.

mWebview.loadUrl("file:///android_asset/nonexistent.html");

you also have to implement the onResume() method or second time it won't work

@Override
public void onResume()
{
    super.onResume();
    webView.onResume();
}

@Override
public void onPause()
{
    super.onPause();
    webView.onPause();
}

The above solution failed for me on Samsung Galaxy S with Android 2.3.3. But I made success trying the below workaround:

	webview.loadUrl("file:///android_asset/nonexistent.html");

I am forcing the webview to load a non existent html file. This seems to be forcing the webview to clean things up.

Try this:

@Override
public void onPause() {
    super.onPause();
    myWebView.onPause();
    myWebView.pauseTimers();
}

@Override
public void onResume() {
    super.onResume();
    myWebView.resumeTimers();
    myWebView.onResume();
}


@Override
protected void onDestroy() {
    myWebView.destroy();
    myWebView = null;
    super.onDestroy();
}

And here's my personal favourite:

@Override
protected void onPause() {
    super.onPause();
    if (isFinishing()) {
        webView.loadUrl("about:blank");
    } else {
        webView.onPause();
        webView.pauseTimers();
    }
}

@Override
protected void onResume() {
    super.onResume();
    webView.resumeTimers();
    webView.onResume();
}

It pauses the webview if the view is only paused, but clears it when the activity is finished.

This requires at least Android 3.0 - API 11 (Honeycomb)

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
	// TODO Auto-generated method stub
	if(keyCode==event.KEYCODE_BACK)
	{
		mWebview.loadUrl("");
		mWebview.stopLoading();
		
		finish();
		
	}
	return super.onKeyDown(keyCode, event);
}

it works

The above approach did not work for me, one which worked for me is :

@Override
protected void onPause() {
    super.onPause();
    ((AudioManager)getSystemService(
            Context.AUDIO_SERVICE)).requestAudioFocus(
                    new OnAudioFocusChangeListener() {
                        @Override
                        public void onAudioFocusChange(int focusChange) {}
                    }, AudioManager.STREAM_MUSIC, 
                    AudioManager.AUDIOFOCUS_GAIN_TRANSIENT);
}

Webview.loadUrl("about:blank");

it is also working

After having encountered this problem it seems that onPause might not be doing anything... for me it was not stopping whatever was playing in background.

so my code now looks like

@Override
protected void onPause() {
	mWebView.onPause();
	super.onPause();
}

@Override
protected void onResume() {
	mWebView.onResume();
	super.onResume();
}

@Override
protected void onSaveInstanceState(Bundle outState) {
	mWebView.saveState(outState);
	super.onSaveInstanceState(outState);
}

@Override
protected void onDestroy() {
	mWebView.destroy();
	mWebView = null;		
	super.onDestroy();
}

Hope it helps anyone with the same problem as me

you can try this

webView.loadUrl("javascript:document.location=document.location");

if the page which is loading is one you can edit then you can write a javascript method which stop the audio and call when you want to stop like.

Javascript function

 function stopAudio(){
    audios=document.querySelectorAll('audio');
      for(i=0;i<audios.length;i++){
       audios[i].stop();
      }
    }

From Andorid Call this method

webView.loadUrl("javascript:stopAudio()");

if the page is not editable by you the you can inject the js code

   @Override
   public void onPageFinished(WebView view, String url) {
      super.onPageFinished(view, url);

      injectScriptFile(view, "js/script.js"); 

   }

How to Inject See Here in Detail

Based on @sommesh's answer:

override fun onPause() {
    super.onPause()

    val audioManager = getSystemService(Context.AUDIO_SERVICE) as AudioManager

    if (Utils.hasOreoSDK26()) {
        val audioAttributes = AudioAttributes.Builder()
                .setUsage(AudioAttributes.USAGE_MEDIA)
                .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
                .build()
        val audioFocusRequest = AudioFocusRequest.Builder(AudioManager.AUDIOFOCUS_GAIN_TRANSIENT)
                .setAudioAttributes(audioAttributes)
                .setAcceptsDelayedFocusGain(true)
                .setWillPauseWhenDucked(true)
                .setOnAudioFocusChangeListener(
                        { focusChange -> Timber.i(">>> Focus change to : %d", focusChange) },
                        Handler())
                .build()
        audioManager.requestAudioFocus(audioFocusRequest)
    } else {
        audioManager.requestAudioFocus({ }, AudioManager.STREAM_MUSIC,
                AudioManager.AUDIOFOCUS_GAIN_TRANSIENT)
    }
}

This works for me.

@Override
protected void onPause() {
	super.onPause();
	if (wViewCampaign != null){
		wViewCampaign.stopLoading(); 
		wViewCampaign.loadUrl("");
		wViewCampaign.reload();
		wViewCampaign = null;
	}
}

You can do it by using the method onPause() of the of WebView when is executed the method onPause()of your Activity :

@override
public void onPause() {
        super.onPause();
        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB){
          webview.onPause();
        }
}

• works for API >= 11 (Honeycomb)

I tried all above answer , but most of them not work for me. so i just write my own solution which works fine in all type of media playing in webview

 String lastUrl = "";
 @Override
    public void onPause() {
        super.onPause();
        lastUrl =  webView.getUrl();
        webView.loadUrl("");
    }

    @Override
    protected void onResume() {
        super.onResume();
        webView.loadUrl(lastUrl);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        webView = null;
    }

This is what finally worked after trying each and every code provided on this page. Uff!

@Override
protected void onPause() {
    super.onPause();
    if (mWebView != null) {
        mWebView.stopLoading();
        mWebView.reload();
    }
}

@Override
protected void onResume() {
    super.onResume();
}

In my situation, the player keep running after the WebView is "onPause." So I check if the WebView is attached to the windows before playing video or music.

It is JavaScriptInterface method for checking WebView's "isAttachedToWindow()" return true/false.

(And I didn't forget to call onPause/onResume in Activity/Fragment.)

This code works perfect for me.

 @Override protected void onPause() {
	super.onPause();
	wv.onPause();
	wv.pauseTimers();
}
	@Override protected void onResume() {
	super.onResume();
	wv.resumeTimers();
	wv.onResume();
}
