How to create http connection which handles automatically if client changes activity

Question

I have crated login application which is a part of my native application building process.There are few end points which uses login session.I am getting successful result for login endpoint but It was not forwarding its session to next activity.For example: If user is loggedIn successful he can access rest of features in further activities. But while I'm trying to switch activity I am getting "User Needs to login".

MainActivity.java

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        jsonResponse = new LoginPOJO();

        // UserLogin Field
        etUserName = (EditText) findViewById(R.id.etUserName);
        // UserLogin Password
        etPassword = (EditText) findViewById(R.id.etPassword);
        // Login Button Image
        btnLogin = (ImageView) findViewById(R.id.btnLogin);
        btnLogin.setOnClickListener(this);
        // User SignUp Button Image
        ImageView btnSignUp = (ImageView) findViewById(R.id.btnSignUp);
        btnSignUp.setOnClickListener(this);
        // Forget Password Textbutton
        TextView frgtPassword = (TextView) findViewById(R.id.forgetpassword);
        frgtPassword.setOnClickListener(this);

You do your login in a service, and then have the service broadcast the successful login to any interested classes.

So According to you I have to parse successful login to interested classes right. But rest of the endpoint won't take these credentials as parameters. How could I be able to send that successful message to interested class.Could you please explain with some sample code. @Gabe Sechan – Arun Apr 04 '17 at 16:08
Look into BroadcastReceivers. Or an event bus. Or an RxJava observable. Or just a bound service with a roll your own callback system. There's dozens of ways to alert activities from a Service, do some research. – Gabe Sechan Apr 04 '17 at 16:10
Ohh okay.. Thank you @Gabe Sechan – Arun Apr 04 '17 at 16:11
Still I am facing same issue. Actually I am trying to hit login endpoint which gives response.Trying to get profile information which is another endpoint,but still it was showing same error user not loggedIn. Which means the endpoint was looking for login session.@Gabe Sechan – Arun Apr 06 '17 at 15:36
