ANSWERED
I am trying to send and int to another activity.There is a button in first act. and it opens second act. and takes int from here to other page.But i cant start two of them at one time. Here is my first activity :
public class ana_ekran extends AppCompatActivity {
    public TextView ana_ekran_kule;
    public TextView ana_ekran_can;
    public  int ana_ekran_can_int=30;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_ana_ekran);
    ana_ekran_kule=(TextView) findViewById(R.id.textView);
    ana_ekran_can=(TextView) findViewById(R.id.textView2);
    ana_ekran_can.setText(ana_ekran_can_int+" CAN");
    }
public void devam (View v){
    Intent i = new Intent(getApplicationContext(),fight_1.class);
    i.putExtra("deger",  ana_ekran_can_int);
    startActivity(i);
    startActivity(new Intent(this,fight_1.class));
}
}
and this is second:
public class fight_1 extends AppCompatActivity {
    public TextView fight_1_can;
    public int fight_1_can_int;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_fight_1);
        fight_1_can=(TextView) findViewById(R.id.textView3);
        int i = getIntent().getIntExtra("deger",-1);
        fight_1_can_int=i;
        fight_1_can.setText(fight_1_can_int+"");
    }
}
