How to play video is gotten from the webpage in WebViewJavaScriptInterface?

[nickcarterney]

Hi Everyone,

I getting issue: load uri videos from the website and play it. In the first time, exoPlayer works well in the MainActivity class. If move the code into WebViewJavaScriptInterface to start Video with url is gotten from the webpage, It will not work :(

Helps me!

ExoMedia version: 4.0.0-preview
Device OS version: 5.1
Device Name: SCL 23 (SAMSUNG GALAXY S5)

To start Video, please click on the white screen area after the webpage is loaded
In the MainActivity class:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.activity_main);

        mVisible = true;
        mControlsView = findViewById(R.id.fullscreen_content_controls);
        mContentView = findViewById(R.id.fullscreen_content);

        webview = (WebView) findViewById(R.id.webviewid);
        videoView = (VideoView)findViewById(R.id.video_view);
        videoView.setVisibility(View.INVISIBLE);

        /* add the following line ---------- */
        final WebSettings settings = webview.getSettings();
        settings.setJavaScriptEnabled(true);
        settings.setJavaScriptCanOpenWindowsAutomatically(true);
        webview.setWebViewClient(new WebViewClient() {
            // autoplay when finished loading via javascript injection
            public void onPageFinished(WebView view, String url) {
                webview.loadUrl("javascript:(function() { document.getElementsByTagName('video')[0].play(); })()");
            }

        });
        webview.setWebChromeClient(new WebChromeClient());
        webview.addJavascriptInterface(new WebViewJavaScriptInterface(videoView, this), JS_INTERFACE);
        webview.getSettings().setMediaPlaybackRequiresUserGesture(false);
        webview.getSettings().setJavaScriptEnabled(true);
        //webview.clearCache(true);
        WebBackForwardList lst_history = webview.copyBackForwardList();
        String link = "http://beeb.vn";
        if(lst_history.getSize() >= 1)
            link = lst_history.getItemAtIndex(lst_history.getCurrentIndex() - 1).getUrl();

        String versionName = BuildConfig.VERSION_NAME;
        webview.getSettings().setUserAgentString("Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko) BeebVN/"+versionName+" in Android OS by beeb.vn");

        webview.loadUrl(link);
    }
    @Override
    public void onBackPressed() {
        if(videoView.getVisibility() == View.VISIBLE)
        {
            videoView.stopPlayback();
            videoView.setVisibility(View.INVISIBLE);
            return;
        }
}

In the WebViewJavaScriptInterface class:

public class WebViewJavaScriptInterface
{
    private VideoView videoView;
    private MainActivity activity;
    public WebViewJavaScriptInterface(VideoView _videoView, MainActivity _activity){
        videoView = _videoView;
        activity = _activity;
    }
    @JavascriptInterface
    public void showAdBanner(String uriHLS) {
//    webView.loadUrl("javascript:window.Android.showAdBanner(showSdkAd())");
        //For now we just picked an arbitrary item to play
        videoView = (VideoView)activity.findViewById(R.id.video_view);
        videoView.setVisibility(View.VISIBLE);
        videoView.setVideoURI(Uri.parse(uriHLS));
//        videoView.setOnPreparedListener(activity);
//        videoView.setOnErrorListener(activity);
        videoView.start();
    }
}

This is more of a www.stackoverflow.com question and not something specific to ExoMedia.
