i want to get the html code of a webpage in android. The webpage url will be given in a edit textbox then when the user will click the button a text view will show the code of that webpage. Please explain and give the code!
Any help would be appreciated!
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet(url);
HttpResponse response = client.execute(request);
String html = "";
InputStream in = response.getEntity().getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
StringBuilder str = new StringBuilder();
String line = null;
while((line = reader.readLine()) != null)
{
str.append(line);
}
in.close();
html = str.toString();
Don't forget to add the internet permission in the AndroidManifest:
<uses-permission android:name="android.permission.INTERNET" />

How to get the html-source of a page from a html link in android?
You need a HttpClient to perform a HttpGet Request. Then you can read the content of that request.
This snippet gives you an InputStream:
public static InputStream getInputStreamFromUrl(String url) {
InputStream content = null;
try {
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response = httpclient.execute(new HttpGet(url));
content = response.getEntity().getContent();
} catch (Exception e) {
Log.e("[GET REQUEST]", "Network exception", e);
}
return content;
}
And this method returns the String:
// Fast Implementation
private StringBuilder inputStreamToString(InputStream is) {
String line = "";
StringBuilder total = new StringBuilder();
// Wrap a BufferedReader around the InputStream
BufferedReader rd = new BufferedReader(new InputStreamReader(is));
// Read response until the end
while ((line = rd.readLine()) != null) {
total.append(line);
}
// Return full string
return total;
}

Use the code above, and set it to a textview like this:
InputStream is =InputStream getInputStreamFromUrl("http://google.com");
String htmlText = inputStreamToString(is);
mTextView.setText(Html.fromHtml(htmlText));
but do the network request in a separate thread/asynctask :)
