Downloading a website to a string

android, contain, download, eclipse, web

Solution

You can get the text using InputStream Reader like this.

try 
{
    URL url = new URL("http://yourwebpage.com");
    // Read all the text returned by the server
    BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
    String str;
    while ((str = in.readLine()) != null) 
    {
     // str is one line of text; readLine() strips the newline character(s)
     // You can use the contain method here.
       if(str.contains(editText.getText().toString))
        {
          You can perform your logic here!!!!!         
        }
    }
    in.close();
} catch (MalformedURLException e) {
} catch (IOException e) {
}

Also add an additional permission in your apps Manifest file:

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

if (group.length() > 0)
  {
            mProgressDialog = new ProgressDialog(this);
            mProgressDialog.setMessage("Bezig met checken voor roosterwijzigingen...");
            mProgressDialog.show();
            try 
            {
                URL url = new URL("http://www.augustinianum.eu/roosterwijzigingen/14062012.pdf");
                BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
                String str;
                while ((str = in.readLine()) != null){

                   if(str.contains(mEtxtGroup.getText().toString())){

                     if(mProgressDialog.isShowing())
                     { 
                        mProgressDialog.dismiss(); 
                     }


                     Toast.makeText(this, "U hebt een roosterwijziging.", Toast.LENGTH_LONG).show();
                     break;
                   }
                }
                in.close();
            } catch (MalformedURLException e) {
                Toast.makeText(this, "Er is een fout opgetreden, probeer opniew.", Toast.LENGTH_LONG).show();
            } catch (IOException e) {
                Toast.makeText(this, "Er is een fout opgetreden, probeer opniew.", Toast.LENGTH_LONG).show();
            }

                     if(mProgressDialog.isShowing())
                     { 
                        mProgressDialog.dismiss(); 
                     }
        }
        else{
            Toast.makeText(this, "Voer een klas in", Toast.LENGTH_LONG).show();
        }

Problem

Having done some basic tutorials, I started making my first real android app in eclipse. I want this app to check if the text in an EditText matches the text on a website (this one: http://www.augustinianum.eu/roosterwijzigingen/14062012.pdf (it contains my school's schedule changes)). I've found out how to make the app check if the text in the EditText matches a string (with the method contains()), so now the only thing I need to do is to download all of the text of that website to a string. But I have no idea how to. Or is there maybe a method which I can check with if a website contains a certain word without downloading the website's text to a string. Thank You! (BTW I'm not English so plz forgive me if I've made some language-related mistakes.) @androider I can't post my code in the comment box so here it is: ``` package me.moop.mytwitter; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.net.MalformedURLException; import java.net.URL; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.TextView; import android.widget.Toast; import android.app.Activity; import android.app.ProgressDialog; public class MainActivity extends Activity { Button mBtnCheck; EditText mEtxtGroup; ProgressDialog mProgressDialog; TwitterUser mTwitterUser; TextView mTxtv1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.nicelayout3); mBtnCheck = (Button) findViewById(R.id.btnCheck); mEtxtGroup = (EditText) findViewById(R.id.etxtGroup); mTxtv1 = (TextView) findViewById(R.id.textView1); } public void checkScheduleChange(View view){ if (view == mBtnCheck){ String group; group = mEtxtGroup.getText().toString(); if (group.length() > 0){ mProgressDialog = new ProgressDialog(this); mProgressDialog.setMessage("Bezig met checken voor roosterwijzigingen..."); mProgressDialog.show(); try { URL url = new URL("http://www.augustinianum.eu/roosterwijzigingen/14062012.pdf"); BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream())); String str; while ((str = in.readLine()) != null){ mProgressDialog.dismiss(); if(str.contains(mEtxtGroup.getText().toString())){ Toast.makeText(this, "U hebt een roosterwijziging.", Toast.LENGTH_LONG).show(); } else{ Toast.makeText(this, "U hebt geen roosterwijzigingen", Toast.LENGTH_LONG).show(); } } in.close(); } catch (MalformedURLException e) { Toast.makeText(this, "Er is een fout opgetreden, probeer opniew.", Toast.LENGTH_LONG).show(); } catch (IOException e) { Toast.makeText(this, "Er is een fout opgetreden, probeer opniew.", Toast.LENGTH_LONG).show(); } } else{ Toast.makeText(this, "Voer een klas in", Toast.LENGTH_LONG).show(); } } } } ``` Here are the button's properties: ``` <Button android:id="@+id/btnCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:clickable="true" android:onClick="checkScheduleChange" android:text="Check" > ```
