    <p>I'm scratching my head at this problem that I can't seem to figure out. What I'm trying to do is extract the URL following the HTTPpost. This will allow me to go through the Oauth process.</p> <p>Currently I'm extracting the whole website into my entity.</p> <p>For example: The data will be posted to <a href="https://mysite.com/login" rel="nofollow">https://mysite.com/login</a> and will redirect after the post to <a href="https://mysite.com/dashboard?code=3593085390859082093720" rel="nofollow">https://mysite.com/dashboard?code=3593085390859082093720</a></p> <p>How does one extract the url?</p> <p>If you need any more information or can direct me in the right direction, all is appreciated! Thank you!</p> <pre class="lang-java prettyprint-override"><code>import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.util.ArrayList; import java.util.List; import org.apache.http.HttpResponse; import org.apache.http.NameValuePair; import org.apache.http.client.ClientProtocolException; import org.apache.http.client.HttpClient; import org.apache.http.client.ResponseHandler; import org.apache.http.client.entity.UrlEncodedFormEntity; import org.apache.http.client.methods.HttpPost; import org.apache.http.impl.client.BasicResponseHandler; import org.apache.http.impl.client.DefaultHttpClient; import org.apache.http.message.BasicNameValuePair; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.util.Log; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.EditText; import android.widget.TextView; import android.widget.Toast; public class LoginActivity extends Activity implements OnClickListener { Button ok,back,exit; TextView result; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.login); // Login button clicked ok = (Button)findViewById(R.id.submit); ok.setOnClickListener(this); result = (TextView)findViewById(R.id.result); } public void postLoginData() { // Create a new HttpClient and Post Header HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("https://mysite.com/login"); try { // Add user name and password EditText uname = (EditText)findViewById(R.id.username); String username = uname.getText().toString(); EditText pword = (EditText)findViewById(R.id.password); String password = pword.getText().toString(); List&lt;NameValuePair&gt; nameValuePairs = new ArrayList&lt;NameValuePair&gt;(2); nameValuePairs.add(new BasicNameValuePair("pseudonym_session[unique_id]", username)); nameValuePairs.add(new BasicNameValuePair("pseudonym_session[password]", password)); httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); // Execute HTTP Post Request Log.w("CANVAS", "Execute HTTP Post Request"); HttpResponse response = httpclient.execute(httppost); String str = inputStreamToString(response.getEntity().getContent()).toString(); Log.w("CANVAS", str); ResponseHandler&lt;String&gt; responseHandler = new BasicResponseHandler(); String ResponseBody = httpclient.execute(httppost, responseHandler); Intent intent = new Intent(getBaseContext(), DashboardActivity.class); startActivity(intent); if(str.toString().equalsIgnoreCase("true")) { Log.w("CANVAS", "TRUE"); result.setText("Login successful"); }else { Log.w("CANVAS", "FALSE"); result.setText(ResponseBody); } } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } 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 try { while ((line = rd.readLine()) != null) { total.append(line); } } catch (IOException e) { e.printStackTrace(); } // Return full string return total; } @Override public void onClick(View view) { if(view == ok){ postLoginData(); } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
