Hi,
I am new in android as well as java programming. I need to develop an
application which will be able to get the information from a webpage
(php page) and use the information in the android app. I write a
simple android app but it doesnt work. Can anyone help me with this?
or give me some guidance?
php part is just echo a string "This is my string";
android part:
public class HelloAndroid extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
String a;
a = callWebPage(
"http://www.uploadhub.com/mobile9/gallery/gallery_android/";,
"?str=helloWorld");
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
tv.setText(a);
setContentView(tv);
}
public String callWebPage(String URLstring, String parameters) {
try {
URL url = new URL(URLstring + parameters);
URLConnection conn = url.openConnection();
// Get the response
BufferedReader rd = new BufferedReader(new
InputStreamReader(conn
.getInputStream()));
while ((s = rd.readLine()) != null) {
return s;
}
} catch (Exception e) {
Log.e("SettingsDialog", "exception in callWebPage");
}
return "error";
}
}
*it always return "error";
