I have two activities namely Registration and Login where I defined a Shared Preferences in the Registration class. On the Registration page, if you click on the button that takes you to the Login Activity from the Registration Activity. I am storing a Shared Preferences value, so that on launching the app the second time, let the app immediately go to the LoginActivity instead of opening the first Activity which is Registration Activity. Here is my SharedPreferences class called Session.

```
private SharedPreferences prefs;

    public Session(Context cntx) {
        // TODO Auto-generated constructor stub
        prefs = PreferenceManager.getDefaultSharedPreferences(cntx);
    }

    public void setusename(String usename) {
        SharedPreferences.Editor editor = prefs.edit();
        editor.putString("username", usename).commit();
        editor.commit();

public Boolean contKey(String key){
        if (prefs.contains(key)){
            return true;
        }else{
           return false;
        }
    }

```

Here is the button in the RegstrationActivity that stores the SharedPreferences value before going to the LoginActivity so that on launch the second time, it opens the LoginActivity class

```
loginLink.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                session = new Session(getApplicationContext());
                session.setusename("hello123");

                Intent intent = new Intent(getApplication(),ActivityLogin.class);
                startActivity(intent);
                finish();
            }
        });

```

I have defined this in the onCreate method of RegistrationActivity class to switch to the ActivityLogin screen on next time the app is launched

```
System.out.println("it got here...2");
        try {
            if (session.contKey("username")) {
                System.out.println("it got here...");
                Intent intent = new Intent(getApplication(), ActivityLogin.class);
                startActivity(intent);
                overridePendingTransition(R.anim.enter, R.anim.exit);
                finish();
            } else {
                System.out.println("it got here...3");
                Intent intent = new Intent(getApplication(), ActivityRegistration.class);
                startActivity(intent);
                finish();
                overridePendingTransition(R.anim.enter, R.anim.exit);
            }
        }catch(Exception ex){

        }

```

Please why is my Shared Preferences not switching to the LoginActivity the second time the is launched. Kindly assist
