Refresh Class

public class RefreshSettings extends Activity implements android.view.View.OnClickListener
{

    Button refresh;
    EditText code;
    String pinCode;
    TelephonyManager telephonyManager;
     String imei;
    @Override
    protected void onSaveInstanceState(Bundle outState) {
        System.out.println("successfull navigation");
        super.onSaveInstanceState(outState);
        setContentView(R.layout.refresh_settings);


        telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
        imei=telephonyManager.getDeviceId();

        refresh=(Button)findViewById(R.id.button_Refresh_Settings);
        refresh.setOnClickListener(this);

        code=(EditText)findViewById(R.id.edittext_Refresh_Code);
    }
}

Answer 1

Change onSaveInstanceState() to onCreate() .

From the documentation I understand that onSaveInstanceState() should be called to store only temporary information,

protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    System.out.println("successfull navigation");
    setContentView(R.layout.refresh_settings);


    telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
    imei=telephonyManager.getDeviceId();

    refresh=(Button)findViewById(R.id.button_Refresh_Settings);
    refresh.setOnClickListener(this);

    code=(EditText)findViewById(R.id.edittext_Refresh_Code);

}
