How to check login in android?

Question

In my project, There is a splashActivity then LoginActivity and on click 社交账号登录 it takes to SocialCountLoginActivity. If someone click on QQ login and if login get success then MainActivity starts. At that time I am finishing the LoginActivity and SocialCountLoginActivity.On restart application it's taking to LoginAcivity instead of MainActivity. What should I do to start MainAcivity directly after successful login?

The following is my screenshot:

The folowing is my socialcountloginactivity part code:

private class  QQUIListener implements IUiListener{

    @Override
    public void onComplete(Object response) {
        //Login sucess
        //finish();
        JSONObject object = (JSONObject) response;
        initOpenidAndToken(object);
        getUserInfo();
    }

    @Override
    public void onError(UiError uiError) {
        //Login fail
    }

    @Override
    public void onCancel() {
        //Cancle Login
    }
}

The following is mainactivity code:

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

    // finish activity
    ActivityManagerUtil.finishSomeOneActivity(SocialAccountLoginActivity.class);
    ActivityManagerUtil.finishSomeOneActivity(LoginActivity.class);

}

Use shared preferences to store login details and check when your application starts. If there is some detail stored then start your main activity else navigate to login activity. If your are very new to android development then go through some session management tutorials you will get better understanding: Like:- http://www.androidhive.info/2012/08/android-session-management-using-shared-preferences/ - https://www.tutorialspoint.com/android/android_session_management.htm
