Estoy luchando con la cadena de visualización HTML en Android WebView.
En el lado del servidor, descargué una página web y escapé caracteres HTML y comillas (usé Python):
my_string = html.escape(my_string, True)
En el lado del cliente de Android: las cadenas no tienen escape por:
myString = StringEscapeUtils.unescapeHtml4(myString)
webview.loadData( myString, "text/html", "encoding");
Sin embargo, webview simplemente los muestra como cadenas literales. Aquí está el resultado:
Editar: agrego la cadena original devuelta desde el lado del servidor:
