You Could Use Firebase OTP Authentication For This Work.

Using Retrofits2 upload file to server in android

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.
