Question

Ok, thanks to below dude biggest issue is fixed. But whatever I print out, none is printed and I cannot print out the message what is typed in class 2 (nimekysija) as well :(. I really need that it stores name and in future it will write down name every time! Thanks for your help!

Problem must be in 2nd class tho. When I update editor.putString(“nimi2”, nimiS); nimiS into “plapla”, then plapla actually shows up :/. So I have really no idea, what is problem!

(updated below classes too to the newest)

Class 1:

package viimane.voimalus;

import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.PreferenceManager;
import android.widget.TextView;

public class MainStuff extends Activity {
    TextView tere;
    String nimi;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.menu);
        tere = (TextView) findViewById(R.id.tvTere);
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
        boolean nimiOlemas = preferences.getBoolean("nimionolemas", false);
        if (nimiOlemas == false){
             startActivity(new Intent("viimane.voimalus.NIMEKYSIJA"));
             finish();
        }
        if (nimiOlemas == true){
            nimi = preferences.getString("nimi2", "");
            System.out.print("töötab!");

            tere.setText("Tere " + nimi);
        }
        System.out.print("töötab2!");
    }
}

        preferences = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
        nimi = (EditText) findViewById(R.id.etNimekysija);
        nimiS = nimi.getText().toString();
        Button kysOk = (Button) findViewById(R.id.bNimekysija);
        kysOk.setOnClickListener(new View.OnClickListener() {      

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                SharedPreferences.Editor editor = preferences.edit();
                editor.putString("nimi2", nimiS); // nime kirjutamine
                editor.putBoolean("nimionolemas", true); // nimi on kirjutatud!
                editor.commit();
                startActivity(new Intent("viimane.voimalus.MAINSTUFF"));
                finish();

            }
        });
    }

Ok I’m guessing you may be new to Java, forgive me if I’m incorrect. You never READ from nimiOlemas.

 boolean nimiOlemas = preferences.getBoolean("nimionolemas", false);
    nimiOlemas = false;
                startActivity(new Intent("viimane.voimalus.NIMEKYSIJA"));
                finish();
               nimiOlemas = true;

I think what you are trying to do is initialize nimiOlemas and then, if it is false, start an activity, call finish, then set nimiOlemas to true, but this is not what you are doing. Is this what you want?

boolean nimiOlemas = preferences.getBoolean("nimionolemas", false);
if (nimiOlemas == false)
{
     startActivity(new Intent("viimane.voimalus.NIMEKYSIJA"));
     finish();
     nimiOlemas = true;
}

= is an assignment, == is a boolean comparison. You say in your question that you check the value of your boolean, but you never do, you only assign to it.
