Hi,

I am creating an application which requires login. I created the main and the login activity.

In the main activity onCreate method I added the following condition:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ...

    loadSettings();
    if(strSessionString == null)
    {
        login();
    }
    ...
}

The onActivityResult method which is executed when the login form terminates looks like this:

@Override
public void onActivityResult(int requestCode,
    						 int resultCode,
    						 Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);
    switch(requestCode)
    {
    	case(SHOW_SUBACTICITY_LOGIN):
    	{
    		if(resultCode == Activity.RESULT_OK)
    		{

    			strSessionString = data.getStringExtra(Login.SESSIONSTRING);
    			connectionAvailable = true;
    			strUsername = data.getStringExtra(Login.USERNAME);
    		}
    	}
    }

The problem is the login form sometimes appears twice (the login() method is called twice) and also when the phone keyboard slides the login form appears again and I guess the problem is the variable strSessionString.

Does anyone know how to set the variable global in order to avoid login form appearing after the user already successfully authenticates?

Thanks!
