Code 128 is a very high-density barcode symbology. (A special version of it called GS1-128 is used extensively world wide in shipping and packaging industries.) It is used for alphanumeric or numeric-only barcodes.

OnBarcode provides several Code 128 Generator libraries, SDK and software, including Code 128 in C#, Code 128 in .NET, Code 128 in Java, Code 128 in ASP.NET, Code 128 in VB.NET, Code 128 Generator.


Code 128 Valid Data Scope

Android Barcode Code 128 supports:

  • all 128 characters of ASCII
  • values 128-255 in accordance with ISO 8859-1. There are referred to as extended ASCII.


How to generate Code 128 barcodes in your Android application?

Generating barcode Code 128 in Java Class example

	Code128 barcode = new Code128();
	   Code 128 Valid data char set:
	        all 128 ASCII characters (Char from 0 to 127)
	//  Set the processTilde property to true, if you want use the tilde character "~"
	//  to specify special characters in the input data. Default is false.
	//  1) All 128 ISO/IEC 646 characters, i.e. characters 0 to 127 inclusive, in accordance with ISO/IEC 646.
	//       NOTE This version consists of the G0 set of ISO/IEC 646 and the C0 set of ISO/IEC 6429 with values 28 - 31
	//       modified to FS, GS, RS and US respectively.
	//  2) Characters with byte values 128 to 255 may also be encoded.
	//  3) 4 non-data function characters.
	//  4) 4 code set selection characters.
	//  5) 3 Start characters.
	//  6) 1 Stop character.
	// Unit of Measure, pixel, cm, or inch
	// barcode bar module width (X) in pixel
	// barcode bar module height (Y) in pixel
	// barcode image margins
	// barcode image resolution in dpi
	// disply barcode encoding data below the barcode
	// barcode encoding data font style
	barcode.setTextFont(new AndroidFont("Arial", Typeface.NORMAL, 12));
	// space between barcode and barcode encoding data
	// barcode bar color and background color in Android device
	specify your barcode drawing area
	    RectF bounds = new RectF(30, 30, 0, 0);
	barcode.drawBarcode(canvas, bounds);
