public void onClick(View v) {
			// TODO Auto-generated method stub
			detailList(v);
			try {
	             //start the scanning activity from the com.google.zxing.client.android.SCAN intent

        Intent intent = new Intent(ACTION_SCAN);

        intent.putExtra("SCAN_MODE", "PRODUCT_MODE");

        startActivityForResult(intent, 0);
} catch (ActivityNotFoundException anfe) {

        //on catch, show the download dialog

        showDialog(Primary.this, "No Scanner Found", "Download a scanner code activity?", "Yes", "No").show();

    }
