I've set up a web server on my own computer using xampp and I am trying to access the server in my App like this:
package com.example.connect2php;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;

import android.os.AsyncTask;

public class MainActivity extends Activity {
static String yahooStackInfo = "http://localhost/21/test03.php";
static String stockSymbol = "";
static String stockDaysLow = "";
static String stockDaysHigh = "";
static String stockChange = "";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new MyAsyncTask().execute();
}
private class MyAsyncTask extends AsyncTask<String, String, String> {
#Override
protected String doInBackground(String... parms) {
// TODO Auto-generated method stub
DefaultHttpClient httpclient = new DefaultHttpClient(
new BasicHttpParams());
HttpPost httppost = new HttpPost(yahooStackInfo);
httppost.setHeader("Content-type", "application/json");
InputStream inputStream = null;
String result = null;
try {
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
inputStream = entity.getContent();
BufferedReader reader = new BufferedReader(
new InputStreamReader(inputStream, "UTF-8"), 8);
StringBuilder theStringBuilder = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
theStringBuilder.append(line + "\n");
}
result = theStringBuilder.toString();
}
catch (Exception e) {
e.printStackTrace();
}
finally {
try {
if (inputStream != null)
inputStream.close();
}
catch (Exception e) {
e.printStackTrace();
}
}
JSONObject jsonObject;
try {
result = result.substring(7);
result = result.substring(0, result.length() - 2);
// Log.v("JSONParser RESULT " , result);
jsonObject = new JSONObject(result);
JSONObject queryJSONObject = jsonObject.getJSONObject("query");
JSONObject resultsJSONObject = queryJSONObject
.getJSONObject("results");
JSONObject quoteJSONObject = resultsJSONObject
.getJSONObject("quote");
stockSymbol = quoteJSONObject.getString("symbol");
stockSymbol = quoteJSONObject.getString("DaysLow");
stockSymbol = quoteJSONObject.getString("DaysHigh");
stockSymbol = quoteJSONObject.getString("Change");
}
catch (JSONException e) {
e.printStackTrace();
}
return result;
}
#Override
protected void onPostExecute(String result) {
TextView line1 = (TextView) findViewById(R.id.line1);
TextView line2 = (TextView) findViewById(R.id.line2);
TextView line3 = (TextView) findViewById(R.id.line3);
line1.setText("Stack: " + stockSymbol + " : " + stockChange);
line2.setText("Days Low " + stockDaysLow);
line3.setText("Days High " + stockDaysHigh);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
But it didn't work. The server code is just:
echo 'cbfunc({"query":{"count":1,"created":"2013-08-24T13:38:58Z","lang":"en-US","results": {"quote":{"symbol":"MSFT","AverageDailyVolume":"47950000","Change":"+2.36","DaysLow":"34.00","DaysHigh":"35.20","YearLow":"26.26","YearHigh":"36.43","MarketCapitalization":"289.5B","LastTradePriceOnly":"34.75","DaysRange":"34.00 - 35.20","Name":"Microsoft Corpora","Symbol":"MSFT","Volume":"225493744","StockExchange":"NasdaqNM"}}}})';

You should use:
http://10.0.2.2/21/test03.php
10.0.2.2 is the special alias to your host loopback interface (i.e., 127.0.0.1 on your development machine)
See: Emulator Network Address Space in the official docs
Though you could have added a logcat, this is most likely why your app fails to obtain the content:
static String yahooStackInfo = "http://localhost/21/test03.php";
This tells your android device to try and access itself. Localhost is the device itself. substitute that with the hostname or IP address of your host.
You might need to check firewall settings too...
Update
Updated with the IP in the comment:
static String yahooStackInfo = "http://223.18.60.177/21/test03.php";

I want to read html code of arduino web server.
I can make web server simply with from example 4. code is below.
#include <SoftwareSerial.h>
#include "WiFly.h"
#define SSID "yum2"
#define KEY "yum000000"
// check your access point's security mode, mine was WPA20-PSK
// if yours is different you'll need to change the AUTH constant, see the file WiFly.h for avalable security codes
#define AUTH WIFLY_AUTH_WPA2_PSK
int flag = 0;
// Pins' connection
// Arduino WiFly
// 2 <----> TX
// 3 <----> RX
SoftwareSerial wiflyUart(2, 3); // create a WiFi shield serial object
WiFly wifly(&wiflyUart); // pass the wifi siheld serial object to the WiFly class
void setup()
{
wiflyUart.begin(9600); // start wifi shield uart port
Serial.begin(9600); // start the arduino serial port
Serial.println("--------- WIFLY Webserver --------");
// wait for initilization of wifly
delay(1000);
wifly.reset(); // reset the shield
delay(1000);
//set WiFly params
wifly.sendCommand("set ip local 80\r"); // set the local comm port to 80
delay(100);
wifly.sendCommand("set comm remote 0\r"); // do not send a default string when a connection opens
delay(100);
wifly.sendCommand("set comm open *OPEN*\r"); // set the string that the wifi shield will output when a connection is opened
delay(100);
Serial.println("Join " SSID );
if (wifly.join(SSID, KEY, AUTH)) {
Serial.println("OK");
} else {
Serial.println("Failed");
}
delay(5000);
wifly.sendCommand("get ip\r");
char c;
while (wifly.receive((uint8_t *)&c, 1, 300) > 0) { // print the response from the get ip command
Serial.print((char)c);
}
Serial.println("Web server ready");
}
void loop()
{
if(wifly.available())
{ // the wifi shield has data available
if(wiflyUart.find("*OPEN*")) // see if the data available is from an open connection by looking for the *OPEN* string
{
Serial.println("New Browser Request!");
delay(1000); // delay enough time for the browser to complete sending its HTTP request string
// send HTTP header
wiflyUart.println("HTTP/1.1 200 OK");
wiflyUart.println("Content-Type: text/html; charset=UTF-8");
wiflyUart.println("Content-Length: 244"); // length of HTML code
wiflyUart.println("Connection: close");
wiflyUart.println();
// send webpage's HTML code
wiflyUart.print("<html>");
wiflyUart.print("<head>");
wiflyUart.print("<title>My WiFI Shield Webpage</title>");
wiflyUart.print("</head>");
wiflyUart.print("<body>");
wiflyUart.print("<h1>Hello World!</h1>");
wiflyUart.print("<h3>10 20 30 40 50</h3>");
wiflyUart.print("Yahoo! Google");
wiflyUart.print("<br/><button>My Button</button>");
wiflyUart.print("</body>");
wiflyUart.print("</html>");
}
}
}
the web server work well.
I wrote simple android code to read html is below.
package com.example.http;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
public class MainActivity extends AppCompatActivity {
private TextView tv;
String urlAddress = "192.168.0.10"; // doesn't show
// String urlAddress = "http://www.kma.go.kr/weather/main.jsp#1159068000"; // work well
Handler handler = new Handler();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv = (TextView)findViewById(R.id.textView1);
Button b = (Button)findViewById(R.id.button1);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
loadHtml();
}
});
}
void loadHtml() {
Thread t = new Thread(new Runnable() {
#Override
public void run() {
final StringBuffer sb = new StringBuffer();
try {
URL url = new URL(urlAddress);
HttpURLConnection conn =
(HttpURLConnection) url.openConnection();
if (conn != null) {
conn.setConnectTimeout(2000);
conn.setUseCaches(false);
if (conn.getResponseCode()
== HttpURLConnection.HTTP_OK) {
BufferedReader br
= new BufferedReader(new InputStreamReader
(conn.getInputStream()));
while (true) {
String line = br.readLine();
if (line == null) break;
sb.append(line + "\n");
}
br.close();
}
conn.disconnect();
}
Log.d("test", sb.toString());
handler.post(new Runnable() {
#Override
public void run() {
tv.setText(sb.toString());
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
});
t.start();
}
}
It work very well with String urlAddress = "http://www.kma.go.kr/weather/main.jsp#1159068000";
but it doesn't show when using
String urlAddress = "192.168.0.10"; instead of before one.
the 192.168.0.10 is allocated ip of arduino from DHCP that i can check on serial monitor.
there is any way to read html from arduino web server??
Your urlAddress isn't a URL, it's just an IP address. You should fully qualify the address with the protocol and the path you want to land on, for example:
String urlAddress = "http://192.168.0.10/";
I would expect you're getting a MalformedURLException.

here is the url of my php page
enter image description here
And some more information: I have Genymotion installed and also bluestack, and VirtaulBox. Do they confilct about port? I mean could these softwares cause conflicting ports Apache xampp and their ports?
My Xampp was working with Port: 80 as shown in below image. So writing below ip address as http://10.0.2.2:80/ worked for me.
If you have wifi and your computer and real device (mobile) is connected to the same wifi you can use NGROK software tool to run and debug your app in your real device.
Run the ngrok.exe and type ngrok http 80, it will give you an address like the below image.
Just use the url in your app where you use your ip address.
It is best to use.
This answer assumes, that the browser screenshot shows a successful page load. I believe, the error page is a bit more gray.
There might be a firewall issue at hand. Since you are using a non-standard port, the firewall exceptions that are installed with XAMPP might not cover that.
Go to the Windows Firewall Advanced settings -> inbound rules. Now add a rule that allows for traffic on the TCP port 800. Make sure, that you uncheck the public profile so that if you are on a public wifi, nobody will be able to connect to this application.
Now check with a browser from the smartphone, if your PHP Application is accessible.
I am fighting with this particular thing but not able to resolve it.. Please help me...
I am trying to connect the android program to a local host which is running on apache server.

Thank you for helping me...
I assume the service endpoint is running on a remote machine but not directly on the mobile device.
In this case localhost would not work because it is a local alias for 127.0.0.1 which resolves to itself.
In your code at the moment, every device will try to reach services hosted by itself. You have to replace localhost by the ip of the server hosting the endpoint
You can use :
private static final String URL = "http:// 10.0.2.2:8081/Test/services/Caluclate?wsdl";
hi friend find your PC allocated IP (Go to CMD and type ipconfig and find IP address) replace "Localhost" with that IP Address .this works for me.
I have developed an Android application that launches a Google Translate Activity using the following code:
...
Intent i = new Intent();
i.setAction(Intent.ACTION_VIEW);
i.putExtra("key_text_input", "What time is it?");
i.putExtra("key_text_output", "");
i.putExtra("key_language_from", "en");
i.putExtra("key_language_to", "es");
i.putExtra("key_suggest_translation", "");
i.putExtra("key_from_floating_window", false);
i.setComponent(new ComponentName("com.google.android.apps.translate",
"com.google.android.apps.translate.translation.TranslateActivity"));
startActivityForResult(i, 0);
...
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.i("yoyo", "in onActivityResult()");
// data is null
}
The parent onActivityResult() is called in my application from the Google Translate Activity, but data is null. Therefore, I assume that there is no way to return any translated text from Google Translate back into my application. Is this correct?
Also, if there was a way to do this, would it be a violation of the API's terms of service? Would it still be a violation if using the Google Translate offline language packs/translation?
If a Google developer (employee) happens to see this and could weigh in, I would appreciate it. I'm really looking for an official response.
Thanks!
I also am curious to know if this is possible.
Meanwhile, if you need to translate simple text here a class that wrap the Google Translate Http Service.
I've never used it in a production enviroment (read a released app) becouse I'm not sure if it's legal.
So if a Google (employee) will answer to your question..maybe could let me know if this approach is legal.
For convenience here the simple AsyncTask that wrap the Google Translate Http Service:
import java.io.IOException;
import java.util.Arrays;
import java.util.Collections;
import java.util.Locale;
import java.util.Random;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;
import com.lus.android.net.RESTClient;
public class TranslatorTask extends AsyncTask<Bundle, Void, String> {
static final private String TAG = "TRANSLATOR";

I am new to android, i want to download the files from FTPs server, On emulater i am able to download files but when i try on target board it is giving error at ftp.auth(SSLFTPClient.AUTH_TLS);
Below is the my code, please suggest me where i am wrong.
package com.android.ftp;
import java.io.File;
import android.app.Activity;
import android.os.Bundle;
import com.enterprisedt.net.ftp.FTPClientInterface;
import com.enterprisedt.net.ftp.FTPConnectMode;
import com.enterprisedt.net.ftp.FTPTransferType;
import com.enterprisedt.net.ftp.ssl.SSLFTPClient;
import com.enterprisedt.util.debug.Level;
import com.enterprisedt.util.debug.Logger;
public class Ftp_testActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String host = "ftp.xyz.com";
String username = "abcd";
String password = "pqr";
String filename = "/mnt/sdcard/video1/747.3gp";
// set up logger so that we get some output
Logger log = Logger.getLogger(Ftp_testActivity.class);
Logger.setLevel(Level.INFO);
SSLFTPClient ftp = null;
try {
// create client
log.info("Creating FTPS (explicit) client");
ftp = new SSLFTPClient();
// disable standard SSL closure
log.info("Setting configuration flags");
ftp.setConfigFlags(SSLFTPClient.ConfigFlags.DISABLE_SSL_CLOSURE);
// set remote host
log.info("Setting remote host");
ftp.setRemoteHost(host);
ftp.setRemotePort(21);
// turn off server validation
log.info("Turning off server validation");
ftp.setValidateServer(false);
// connect to the server
log.info("Connecting to server " + host);
ftp.connect();
// switch to SSL on control channel
log.info("Switching to FTPS (explicit mode)");
ftp.auth(SSLFTPClient.AUTH_TLS);
// log in
log.info("Logging in with username=" + username + " and password="
+ password);
ftp.login(username, password);
log.info("Logged in");
ftp.setConnectMode(FTPConnectMode.PASV);
ftp.setType(FTPTransferType.ASCII);
putGetDelete(filename, ftp);
log.info("Successfully transferred in ASCII mode");
// Shut down client
log.info("Quitting client");
ftp.quit();
log.info("Example complete");
} catch (Exception e) {
e.printStackTrace();
}
}
private static void putGetDelete(String name, FTPClientInterface ftp)
throws Exception {
ftp.put(name, name);
ftp.get(name + ".copy", name);
ftp.delete(name);
File file = new File(name + ".copy");
file.delete();
}
}
You should try:
ftp.setRemotePort(990);
where 990 is port SSL default.
