i cant send data from andorid device to url
please help me !
this is my class
what is problem of my code ?
package com.example.test;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.URL;
import java.net.URLConnection;
import java.net.URLEncoder;
import android.os.AsyncTask;
public class loginserver extends AsyncTask{
private String Link="";
private String User="";
private String Pass="";
public loginserver(String link,String user,String pass){
Link=link;
User=user;
Pass=pass;
}
#Override
protected String doInBackground(Object... arg0) {
try{
String data=URLEncoder.encode("username","UTF8")+"="+URLEncoder.encode(User,"UTF8");
data+="&"+URLEncoder.encode("password","UTF8")+"="+URLEncoder.encode(Pass,"UTF8");
URL mylink=new URL(Link);
URLConnection connect=mylink.openConnection();
connect.setDoOutput(true);
OutputStreamWriter wr=new OutputStreamWriter(connect.getOutputStream());
wr.write(data);
wr.flush();
BufferedReader reader=new BufferedReader(new InputStreamReader(connect.getInputStream()));
StringBuilder sb=new StringBuilder();
String line=null;
while((line=reader.readLine()) !=null){
sb.append(line);
}
Main.res = sb.toString();
}catch(Exception e){
}
return "";
}
}
and this is my main code
problem in class code or main code?

Toast.makeText(getApplicationContext(), res, Toast.LENGTH_LONG).show();
tm.cancel();
}
}
});
}
},1, 1000);
}
}
the php code work true - but i cant send data from android device
is ther any body know my mistakes ?
at first you have to setup the internet permissions in the manifest.
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
It would also be helpful if you check at first if the network is available.
private boolean networkIsAvailable(Context con) {
ConnectivityManager cm = (ConnectivityManager)
con.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = cm.getActiveNetworkInfo();
return networkInfo != null && networkInfo.isConnected();
}
After that, you have to work with the HttpClient.

You Could Use Firebase OTP Authentication For This Work.
I am working on an application that would send an image with 2 strings but I am not as experienced in this field so i was lost for the last day or two trying to figure this out as i started with a script but didn't work for me

Do not access the Android UI toolkit from outside the UI thread
Pass editText_mail_id.getText() and editText_chat_message.getText() as parameters to your async task or set it in onPreExecute to some variable
Like :
private class SendMessage extends AsyncTask<String, Void, String> {
private String mailId;
private String msgText;
#Override
protected void onPreExecute() {
super.onPreExecute();
mailId = editText_mail_id.getText().toString();
msgText = editText_chat_message.getText().toString();
}
Change url in doInBackground as :
String url = Util.send_chat_url+"?email_id="+mailId+"&message="+msgText;
you can create class for storing your parameter like i do,
Just create one class
example :
public class MyTaskParams
{
String mailId;
String message;
public MyTaskParams(String mailId, String message)
{
this.mailId = mailId;
this.message = message;
}
}
public class SendMessage extends AsyncTask<MyTaskParams, Void, String {
#Override
protected String doInBackground(MyTaskParams... params) {
String mailId = params[0].mailId;
String message = params[0].message;
String url = Util.send_chat_url+"?email_id="+ mailId +"&message="+ message;
}
}
so you can just call like this
MyTaskParams params = new MyTaskParams(editText_mail_id.getText().toString(),editText_chat_message.getText().toString());
SendMessage myTask = new SendMessage();
myTask.execute(params);
with this code you can call SendMessage Class from any activity, dont bind your asynctask with get text because if you do that you just can use SendMessage only in that activity
Hope this can help you.
