    private Button m_objBtnDial; 




    int m_nLineNo = -1;
    boolean m_objContactFlag;

    public static Phone m_objPhone;
    private static String[] m_objPhoneNum = new String[VaxSIPUserAgent.TOTAL_LINE_COUNT];

    public void onCreate(Bundle savedInstanceState)
    {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);

        Phone.m_objDialPad = this;

        Intent intent = getIntent();

        int nIntentExtraLineNo = intent.getIntExtra("LineNo", 1);
        m_nLineNo = nIntentExtraLineNo; 



        final int [] aLineArray =  new int[VaxSIPUserAgent.TOTAL_LINE_COUNT - 1];

        int nIndex = 0;

        for (int nLineNo = 0; nLineNo < VaxSIPUserAgent.TOTAL_LINE_COUNT; nLineNo++)
        {
            if(m_nLineNo ==  nLineNo)
                continue;

            aLineArray[nIndex] =  nLineNo + 1;
            nIndex++;

        }

        String sLineStatus = VaxStatus.m_objVaxStatus.GetLineStatus(m_nLineNo);
        OnStatusPhone(sLineStatus);


             String sPhoneNo = intent.getStringExtra("PhoneNo");

        if(sPhoneNo != null)
        {
            m_objPhoneNum[nIntentExtraLineNo] = sPhoneNo;
        }

        m_objEditDialscreen.setText(m_objPhoneNum[nIntentExtraLineNo]);
    }




    @Override
    protected void onStart() 
    {



        UpdateDialBtn();


        if(m_objContactFlag == false)
            m_objEditDialscreen.setText(m_objPhoneNum[m_nLineNo]);

        IncommingCallSlider.m_objCallSlider.SetActiveActivity(this, R.id.dialpad);
        IncommingCallRing.m_objIncommingCallRing.SetActiveActivity(this);

        DialCallTone.m_objDialCallTone.SetActiveActivity(this);

        super.onStart();
    }



    @Override
    protected void onStop() 
    {
        m_objPhoneNum[m_nLineNo] = m_objEditDialscreen.getText().toString();
        super.onStop();
    }


 }

Answer 1

Add the following method to your Dial activity:

@Override
    protected void onPause() 
    {
       finish();   
    }

Answer 2

onCreate is called when the Activity is created.

Once you come back, onResume will be called.

If you have some code that should run both on onCreate and onResume, you should put it in onResume, while onResume is always called, whether you are creating a new activity or you are coming back to an already running activity.

See the activity life-cycle in this diagram:
