I am creating an android application that needs to interact with a local web server(WAMP). WAMP has a php file that just echos Hello world. This application requests for this page but when I run the application and click on the button that fires the request event, there are no results printed on the EditText saying Helloworld. The following is the code:
package com.mobilevoter;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URLConnection;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class mobilevoter extends Activity implements OnClickListener {
Button proceed;
EditText voter_number;
EditText id_number;
URLConnection conn;
BufferedReader myreader;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
proceed=(Button)findViewById(R.id.proceed_btn);
voter_number=(EditText)findViewById(R.id.editText_voternumber);
id_number=(EditText)findViewById(R.id.editText_idnumber);
proceed.setOnClickListener(this);
}
@Override
public void onClick(View src) {
if(src==proceed){
HttpClient authenticationClient= new DefaultHttpClient();
HttpPost url_post=new HttpPost("http://10.0.2.2/practice/index.php");
HttpResponse response;
try
{
response=authenticationClient.execute(url_post);
HttpEntity authenticationEntity=response.getEntity();
InputStream authenticationStream=authenticationEntity.getContent();
BufferedReader myreader=new BufferedReader(new InputStreamReader(authenticationStream));
String inputStream;
wh开发者_C百科ile((inputStream=myreader.readLine())!=null)
{
voter_number.setText(inputStream);
}
}
catch(Exception exception)
{
System.out.println(exception.getMessage());
}
/*finally
{
try
{
myreader.close();
}
catch(IOException ioexception)
{
System.out.println(ioexception.getMessage());
}
}*/
}
}
}
The manifest looks like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mobilevoter"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".mobilevoter"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.INTERNET" />
</manifest>
I will really appreciate the help. Thanx.
Can you reach that URL from the browser app built-in the mobile/emulator?
If not, you need to check your network setup. 10.0.2.2 seems to be ok from what the guide says. Perhaps there is a firewall? Does the WAMP server listen on port 80?
http://progrium.com/localtunnel/
$ gem install localtunnel
$ localtunnel 8000
share this url:
http://xyz.localtunnel.com
You'll need RubyGems installed, but this is the easiest solution for me.
