/**
  * Things to note when playing videos using WebView:
  * 1. Add network access permissions (and other required permissions);
  * 2. The method shouldOverrideUrlLoading in WebViewClient can be used to implement links to click on webView pages;
  * 3. Video playback in WebView needs to be added (new WebChromeClient());
  * 4. When the video is vertical, click on full screen. If you want to switch to the horizontal full screen state, you must be in the configuration file.
  * Add android:configChanges="orientation|screenSize" statement to the configuration file.
  * 5. If the video cannot be played, or the playback comparison card can be used, hardware acceleration can be used, that is, it can be added in the configuration file of the Application or Activity.
  * android:hardwareAccelerated="true".
