How to generate POSTNET barcodes in your Android application?

Generating barcode POSTNET in Java Class example

	   POSTNET Valid data length: 5, 6, 9, 11 digits only, excluding the last checksum digit
	*/
	barcode.setData("01234");
	
	// POSTNET Short bar vs high bar ratio
	barcode.setShortTallRatio(0.4f);
	
	// Unit of Measure, pixel, cm, or inch
	barcode.setUom(IBarcode.UOM_PIXEL);
	// barcode bar module width (X) in pixel
	barcode.setX(1f);
	// barcode bar module height (Y) in pixel
	barcode.setY(75f);
	
	// barcode image margins
	barcode.setLeftMargin(10f);
	barcode.setRightMargin(10f);
	barcode.setTopMargin(10f);
	barcode.setBottomMargin(10f);
	
	// barcode image resolution in dpi
	barcode.setResolution(72);
	
	// disply barcode encoding data below the barcode
	barcode.setShowText(true);
	// barcode encoding data font style
	barcode.setTextFont(new AndroidFont("Arial", Typeface.NORMAL, 12));
	// space between barcode and barcode encoding data
	barcode.setTextMargin(6);
	barcode.setTextColor(AndroidColor.black);
	
	// barcode bar color and background color in Android device
	barcode.setForeColor(AndroidColor.black);
	barcode.setBackColor(AndroidColor.white);
	
	/*
	specify your barcode drawing area
	    */
