I'm using that code to send POST requests.
Now i need to add header to this, any ways of doing it?
In Google most ways is to use another methods, like HttpPost and addHeader method.
try {
System.out.println("FirebaseInstanceId.getInstance().getToken()" + token);
//String data = URLEncoder.encode("?api-fcm=register", "UTF-8");
String data = URLEncoder.encode("regid", "UTF-8")
+ "=" + URLEncoder.encode(FirebaseInstanceId.getInstance().getToken(), "UTF-8");
if ( ContextCompat.checkSelfPermission( this, Manifest.permission.READ_PHONE_STATE ) == PackageManager.PERMISSION_GRANTED ) {
data += "&" + URLEncoder.encode("serial", "UTF-8") + "=" + URLEncoder.encode( Build.SERIAL, "UTF-8");
}
data += "&" + URLEncoder.encode("device_name", "UTF-8")
+ "=" + URLEncoder.encode(getDeviceName(), "UTF-8");
data += "&" + URLEncoder.encode("os_version", "UTF-8")
+ "=" + URLEncoder.encode(getAndroidVersion(), "UTF-8");
String text = "";
BufferedReader reader = null;
try {
URL url = new URL("http://somelink");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(data);
wr.flush();
reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
text = sb.toString();
} catch (Exception ex) {
Do code like this:
HttpUrlConnection myURLConnection = (HttpUrlConnection)conn;
myURLConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
myURLConnection.setRequestProperty("Content-Length", "" + postData.getBytes().length);
myURLConnection.setRequestProperty("Content-Language", "en-US");
add this after line:
URLConnection conn = url.openConnection();
and here "Content-Type", "Content-Length", "Content-Language" are headers here.
Thanks and let me know if need more.
happy Coding!!

I'm using a Service in different process of my app using android:process=":MyService" and I recognized that my AsyncTasks in MyService class doesn't work and execute, so how can I sync my datas with my Server in MyService class?
I just want to update my Server from this class cause it's a ForegroundService that should be active most of the times. I believe that defining MyService class as a separate process helps my app's battery usage. I've already defined an inner class and used it inside MyService class but it doesn't work at all, I also tried to use another custom asyncTask class Object in MyService class but it doesn't work either
here's an example of my code in MyService class:
static class UpdatePoint extends AsyncTask<String,String,String>{
#Override
protected String doInBackground(String... strings) {
String userId = user.get(SessionManager.getKeyId()).toString();
String coin = strings[1];
String step = strings[2];
String log_lat = strings[3];
String log_lng = strings[4];
String log_zone = strings[5];
String log_address = strings[6];
//Log.d("updatePoint","coin:"+coin+", step:"+step);
try {
String update_point_url = "http://mohregroup.ir/db-mapapa/updatePoint.php";
URL url = new URL(update_point_url);
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
httpURLConnection.setConnectTimeout(5*1000);
httpURLConnection.setRequestMethod("POST");
httpURLConnection.setDoOutput(true);
httpURLConnection.setDoInput(true);
OutputStream outputStream = httpURLConnection.getOutputStream();
BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(outputStream, "UTF-8"));
String data = URLEncoder.encode("userId", "UTF-8") + "=" + URLEncoder.encode(userId, "UTF-8")
+ "&" + URLEncoder.encode("coin", "UTF-8") + "=" + URLEncoder.encode(coin, "UTF-8")
+ "&" + URLEncoder.encode("step", "UTF-8") + "=" + URLEncoder.encode(step, "UTF-8")
+ "&" + URLEncoder.encode("log_lat", "UTF-8") + "=" + URLEncoder.encode(log_lat, "UTF-8")
+ "&" + URLEncoder.encode("log_lng", "UTF-8") + "=" + URLEncoder.encode(log_lng, "UTF-8")
+ "&" + URLEncoder.encode("log_zone", "UTF-8") + "=" + URLEncoder.encode(log_zone, "UTF-8")
+ "&" + URLEncoder.encode("log_address", "UTF-8") + "=" + URLEncoder.encode(log_address, "UTF-8");
bufferedWriter.write(data);
bufferedWriter.flush();
bufferedWriter.close();
outputStream.close();
InputStream inputStream = httpURLConnection.getInputStream();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "iso-8859-1"));
StringBuilder response = new StringBuilder();
String line;
while ((line = bufferedReader.readLine()) != null) {
response.append(line);
}
//Log.d("updatePoints response:", response.toString().trim());
bufferedReader.close();
inputStream.close();
httpURLConnection.disconnect();
Timber.d("done Successfully!");
return response.toString();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
and using it inside another method of MyService class :
if (getAddress() != null) {
if (getAddress().getFeatureName() == null &&
getAddress().getAddressLine(0) != null) {
new UpdatePoint().execute(String.valueOf(coins),
String.valueOf(steps),
String.valueOf(originLocation.getLatitude()),
String.valueOf(originLocation.getLongitude()),
getAddress().getFeatureName(), "not titled");
} else if (getAddress().getFeatureName() != null &&
getAddress().getAddressLine(0) == null) {
new UpdatePoint().execute(String.valueOf(coins),
String.valueOf(steps),
String.valueOf(originLocation.getLatitude()),
String.valueOf(originLocation.getLongitude()),
"not titled", getAddress().getAddressLine(0));
} else {
new UpdatePoint().execute(String.valueOf(coins), String.valueOf(steps),
String.valueOf(originLocation.getLatitude()), String.valueOf(originLocation.getLongitude()),
getAddress().getFeatureName(), getAddress().getAddressLine(0));
}
} else {
new UpdatePoint().execute(String.valueOf(coins), String.valueOf(steps),
String.valueOf(originLocation.getLatitude()), String.valueOf(originLocation.getLongitude()),
"not titled", "not titled");
}
So, any Ideas about
how to use an asyncTask in a service with different process?
or
any other way in order to update the server from a service with different process?
any helps would be appreciated a lot!
Thanks.
One way could be using timer and when timer is finished you can call asynctask and reset the timer again.
I need to fetch data from this site http://www.speech.cs.cmu.edu/cgi-bin/tools/lmtool/run

It's better to use OkHttp for network requests. You can try this example for multipart request.
Thank you for your help #MaxV i sloved my issue by using OkHttp and POSTMAN
I decided to connect to an external host my app but don't work. How can i do?
this is an exemple:
String login_url = "http://***.**.**.**/fileman/**/register.php";
// String login_url = "http://10.0.2.2/code/register.php";
String method = params[0];
if (method.equals("register")) {
String name = params[1];
String user_name = params[2];
String user_pass = params[3];
try {
URL url = new URL(reg_url);
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
httpURLConnection.setRequestMethod("POST");
httpURLConnection.setDoOutput(true);
//httpURLConnection.setDoInput(true);
OutputStream OS = httpURLConnection.getOutputStream();
BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(OS, "UTF-8"));
String data = URLEncoder.encode("user", "UTF-8") + "=" + URLEncoder.encode(name, "UTF-8") + "&" +
URLEncoder.encode("user_name", "UTF-8") + "=" + URLEncoder.encode(user_name, "UTF-8") + "&" +
URLEncoder.encode("user_pass", "UTF-8") + "=" + URLEncoder.encode(user_pass, "UTF-8");
bufferedWriter.write(data);
bufferedWriter.flush();
bufferedWriter.close();
OS.close();
InputStream IS = httpURLConnection.getInputStream();
IS.close();
//httpURLConnection.connect();
httpURLConnection.disconnect();
ritorno = "Registration Success...";
return ritorno;
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
with localhost work, but when i use my url don't work.. (if i use my url on google adress he work)
what is wrong?
Are you supposed to be using login_url rather than reg_url in URL url = new URL(reg_url)? I think reg_url was initialized with something else.
Good Evening
I am attempting to create a simple android application that asks the user for login information; the details of which are stored in an SQL database.
However the php displays an error Notice: Undefined variable: username and Notice: Undefined variable: password.
I believe the error can be traced to the Java class responsible for connecting to the database. Specifically the String username, and password.
protected String doInBackground**(String... arg0)** {
try{
**String username = (String)arg0[0];**
**String password = (String)arg0[1];**
String link="//Removed//";
String data = URLEncoder.encode("username", "UTF-8") + "=" + URLEncoder.encode(username, "UTF-8");
data += "&" + URLEncoder.encode("password", "UTF-8") + "=" + URLEncoder.encode(password, "UTF-8");
URL url = new URL(link);
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write( data );
wr.flush();
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuilder sb = new StringBuilder();
String line = null;
// Read Server Response
while((line = reader.readLine()) != null)
{
sb.append(line);
break;
}
return sb.toString();
}
catch(Exception e){
return new String("Exception: " + e.getMessage());
}
}
Because I am very new to android I have been following the http://www.tutorialspoint.com/android/android_php_mysql.htm
guide in order to create the system. I would greatly appreciate any help with the matter.
Thank you.
PHP CODE
<?php
$con=mysqli_connect("//","//","//","//");
if (mysqli_connect_errno($con))
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$username = $_POST['username'];
$password = $_POST['password'];
$result = mysqli_query($con,"SELECT Role FROM my_db WHERE
Username='$username' and Password='$password'");
$row = mysqli_fetch_array($result);
$data = $row[0];
if($data){
echo $data;
}
mysqli_close($con);
?>
