WebView midrange video auto play and stop playing when exiting

Background:
The project requirement is to go to the page to automatically play audio or video (non-local resources) when the page closes when the audio or video is turned off. Now the implementation of the situation is: the auto-play function on some phones can automatically play and have sound, and some phones also play but no sound, when the user clicks or generates a trigger condition will have a sound; exit close current activity, audio or video is not turned off, still playing.

Workaround:

1. Turn off audio or video when activity exits

Rewrite the activity's OnDestroy () method to add the Webview.destroy () method to the method.

@Overrideprotected void onDestroy() {    super.onDestroy();    //为了使WebView退出时音频或视频关闭    webView.destroy();}

2. Audio or video auto-play

Write an AutoPlay method that executes the method in the activity's OnCreate () method, Webviewclient, onpagefinished ().

@Overridepublic void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.webview_activity);    ......    autoPlay();}private class MyWebViewClient extends WebViewClient {    @Override    public boolean shouldOverrideUrlLoading(WebView view, String url) {       ......    }    @Override    public void onPageFinished(WebView view, String url) {       ......        autoPlay();    ......    }    @Override    public void onPageStarted(WebView view, String url, Bitmap favicon) {        ......    }}/** * 使视频或音频自动播放,默认播放第一条 */public void autoPlay() {    //音频自动播放js方法    String audioJs = "javascript: var v = document.getElementsByTagName(‘audio‘); v[0].play();";    webView.loadUrl(audioJs);    //视频自动播放js方法    String videoJs = "javascript: var v = document.getElementsByTagName(‘video‘); v[0].play();";    webView.loadUrl(videoJs);}

Insufficient:

如果WebView中既有音频也有视频的话，会导致它们同时播放；如果音频播放过程中要播放视频，音频要暂停，视频播放完音频要接着播放；还有一些更加复杂的场景这个并没有实现。

The above is only personal opinion, there is a problem please give us a lot of advice.
