Hello all, I have started to work with the WebView component of Android Platform, but the API to load data to the component is confusing me, because it includes a parameter with a encoding.
In both methods: public void loadData (String data, String mimeType, String encoding); public void loadDataWithBaseURL (String baseUrl, String data, String mimeType, String encoding, String historyUrl); you have to specify an encoding. In both cases, the API documentation says that is is the encodign of the data (data parameter). Well, as know, if you provide data as a String object, the String is internally stored in UTF-16 (unicode). To get a String object from a external source, you need to specify the external source encoding to convert it to UTF-16 and get the String internal representation (String(byte[] data, String encoding)). So, at this moment, when you have an String instance, everything from the original source has been converted to UTF-16. So, why do you need to specify an encoding if you are providing the data as a String object? I don't know the internal implementation of WebKit, but let's suppose that, WebKit has a method, to render a source, providing as content an InputStream and a default encoding. Well, as I know, when you process a HTML page, you use the default encoding to read the HTML characters, and if you find a <meta> tag specifing a different encoding, from that moment, you have to use the new encoding to decode the characters of the HTML page. But what happens if you supply a HTML page that contains this <meta> tag: <meta HTTP-EQUIV="content-type" CONTENT="text/html; charset=ISO-8859-1"/> using one of the methods specified at the top of this post, how are you going to read ISO-8859-1 encoding from a String that it is in UTF-16 encoding? if the WebKit filtering this <meta> tags, and doesn't taking in account the encoding specified in this tag? Well, all of this is very confusing for me, because I don't understand why the API includes this encoding parameter. I also don't know if the <meta> encoding tags are filtered when the source is provided as a String? Can anyone solve my doubts?
