How to show response in webview?

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://mymobilece.com/api/api_getexammaterials.php?id=27");
HttpResponse response = httpclient.execute(httppost);
String responseBody = EntityUtils.toString(response.getEntity());
System.out.println("Respnce body :: " + responseBody);
bufferedReader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

StringBuffer stringBuffer = new StringBuffer("");
String line = "";
String LineSeparator = System.getProperty("line.separator");

while ((line = bufferedReader.readLine()) != null) {
        stringBuffer.append(line + LineSeparator);
    }
bufferedReader.close();

Toast.makeText(View_Materials_Activity.this, "Finished", Toast.LENGTH_LONG).show();

String webData = stringBuffer.toString();
String webData1 = URLDecoder.decode(webData);
System.out.println("data :; " + webData1);
webView.loadData(webData, "text/html", "UTF-8");
webView.loadDataWithBaseURL("http://www.ilias.de/docu/", webData,"text/html", "UTF-8", "about:blank");

Answer 1

As you can see, an HTTP response is not HTML. It’s HTTP. It might contain HTML. Use HttpResponse.getEntity and then Entity.getContent and you can read the data (presumably HTML) from the stream. Then you can use WebView.loadData to load that data.

Update:
Your data might also be gzipped… Take a look at this other SO post for more details.
