Cuando se trabaja con el WebView es posible que llegue el momento en el que ocupemos subir un archivo al sitio, cosa que se logra con el WebChromeClient pero la manera de hacerlo ha cambiado con los distintos niveles de API; por ejemplo para el nivel de API >11 se utilizan los métodos openFileChooser(ValueCallback) o openFileChooser(ValueCallback, String) los cuales estan marcados como @hide, para el API >16 se utiliza el médoto openFileChooser(ValueCallback, String, String) que también 由于 Android 本身的限制，在 webview 中上传文件需要自行重载 `openFileChooser ()` 或者 `onShowFileChooser ()` 方法.
