Question

How can I get data from a site to a variable x?
I want that everytime I use this x, x will get his data from this site.
for example how can I get this data 3.856 from the site http://www.dollargate.net/ ?

Answer 1

/first, download the site:

DefaultHttpClient client = new DefaultHttpClient();
HttpGet request= new HttpGet(url);      
HttpResponse response = client.execute(request);
String content = EntityUtils.toString(response.getEntity());

then look for the following text in content:

<div id="tabcontent1">
    <div id="dollar_1">שער הדולר היציג הוא:</div>
    <div id="dollar_2">

the number will be right after this text

PS: don’t forget to add permissions in your manifest:

<uses-permission android:name="android.permission.INTERNET"/>
