Solution 1:

Cheers! Problem got resolved.

There were no appropriate intantiation of the phone number field of the mSmsManager.sendTextMessage() method. Alas! how silly mistake i made which took some time to figure out. I believe i got mislead because of nesting of onClickListener() methods. He he...

I am reposting the correct code to let be helpful for others.

publicclassDialogActivityextendsActivity 
{   
    private Dialog mDialog;
    String editTextEnterMobileNum;

    @OverrideprotectedvoidonCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);

        AlertDialog.Builderbuilder=newAlertDialog.Builder(this);
        builder
        .setTitle("Incoming Server Message")
        .setMessage("text")
        .setCancelable(false)
        .setPositiveButton("eReceipt?", newDialogInterface.OnClickListener() 
        {
            publicvoidonClick(DialogInterface dialog, int id) 
            {
                dialog.cancel();

                mDialog = newDialog(DialogActivity.this);
                mDialog.setContentView(R.layout.ereceipt_dialog);                       
                mDialog.setTitle("User Input");
                finalEditTextphoneNo= (EditText) mDialog.findViewById(R.id.eReceiptEditText);
                mDialog.findViewById(R.id.eReceiptOkButton).setOnClickListener(
                        newOnClickListener() {

                            @OverridepublicvoidonClick(View v) {
                                dismissDialog();
                                Stringnumber= phoneNo.getText().toString();
                                try{
                                    android.telephony.SmsManagermSmsManager= android.telephony.SmsManager.getDefault();
                    mSmsManager.sendTextMessage(number, null, SmsReceiver.msgContent, null, null);
                                    Toast.makeText(getApplicationContext(), "Your SMS has sent successfully!", Toast.LENGTH_LONG).show();

                                }

                                   catch(Exception e){
                                        Toast.makeText(getApplicationContext(), "Your SMS sent has failed!", Toast.LENGTH_LONG).show();
                                        e.printStackTrace();
                                   }                        

                            }
                        });

                mDialog.show();              
          }
        })
        .setNegativeButton("Exit", newDialogInterface.OnClickListener() 
        {
            publicvoidonClick(DialogInterface dialog, int id) 
            {
                dialog.cancel();

            }
        });
        AlertDialogalert= builder.create();
        alert.show();
        //finish();
    }

    publicvoiddismissDialog() {
        if (mDialog != null) {
            mDialog.dismiss();
            mDialog = null;
        }
    }

}

Solution 2:

You are not getting the text from the number field.

Replace the row

mSmsManager.sendTextMessage(editTextEnterMobileNum, null, SmsReceiver.msgContent, null, null);

with this one

mSmsManager.sendTextMessage(editTextEnterMobileNum.getText().toString(), null, SmsReceiver.msgContent, null, null);
