Method getText() must be called from the UI Thread (Android Studio)

Question

I\'m trying to create a login for an application. However I have a problem.

This is my code:

package com.forgetmenot.loginregister;


import java.uti

You're accessing the UI thread from a background thread here:

String username = uname.getText().toString();
String pass = password.getText().toString();

What you want to do is just pass the username/password strings in to your background task constructor or you could pass them directly to the execute method. I prefer to define them in to the constructor if they are going to be required (like yours are).

Define your LoginTask like

String uname;
String password;
public Login(String username, String password({
    this.uname = username;
    this.password = password;
}

Then in doInBackground() you use the members instead.

List params = new ArrayList();
params.add(new BasicNameValuePair("u",this.username));
params.add(new BasicNameValuePair("p",this.pass));
json = jParser.makeHttpRequest(url_login, "GET", params);

Edit - so then your new Login().execute() call would look more like this

new Login(uname.getText().toString(), password.getText().toString()).execute();
