/**
 * 经过大量的测试，按照以下方式才能保证JS脚本100%注入成功：
 * 1、在第一次loadUrl之前注入JS（在addJavascriptInterface里面注入即可，setWebViewClient和setWebChromeClient要在addJavascriptInterface之前执行）；
 * 2、在webViewClient.onPageStarted中都注入JS；
 * 3、在webChromeClient.onProgressChanged中都注入JS，并且不能通过自检查（onJsPrompt里面判断）JS是否注入成功来减少注入JS的次数，因为网页中的JS可以同时打开多个url导致无法控制检查的准确性；
 *
 * @deprecated Android 4.2.2及以上版本的 addJavascriptInterface 方法已经解决了安全问题，如果不使用“网页能将JS函数传到Java层”功能，不建议使用该类，毕竟系统的JS注入效率才是最高的；
