This is my code

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mButt=(Button)findViewById(R.id.button1);

        mDSLCode="a1";

        mButt.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub

                submitData();
            }

        });

    }
private void submitData()
    {
        try {


        String VndCode=mFarmer_codetxt.getText().toString();
        String ltrs=mLtrs.getText().toString();
        String metrolac=mtext.getText().toString();
        final String mdrq=mDRQ.getText().toString();
        Calendar c = Calendar.getInstance();
        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String submitedDate = df.format(c.getTime());



        insertLC(VndCode, ltrs, metrolac, mdrq, mDSLCode, submitedDate, null, null);

        DbBackup.copyDatabase(getApplicationContext());


        } catch (Exception e) {
            // TODO: handle exception
        }
    }

        // TODO Auto-generated method stub
        mDbA= new DBAdapter(this);
        mDbA.open();
        try {
            long i = mDbA.insertLC(vendorcode, lotsquantity, metrolacreading, drq, dslprogrammecode, entrydatetime, remarks, status);
            if(i != -1){
