Android EAN 128 Barcode Generator Introduction

Android EAN 128 barcode API is an EAN 128 generator for Android apps, designed for creating EAN 128 barcode on Android platform.

  • Android EAN 128 SDK is entirely developed for Android platform
  • Android EAN 128 generator is completely built in Android 1.5 SDK
  • Developer Licenses for this Android EAN 128 library are royalty-free and perpetual

GS1-128 is an application standard of the GS1 implementation using the Code 128 barcode specification. The former correct name was UCC/EAN-128. Other no longer used names have included UCC-128 and EAN-128. GS1-128 uses a series of Application Identifiers to include additional data such as best before dates, batch numbers, quantities, weights and many other attributes needed by the user.

OnBarcode provides several GS1 128 Generator library, SDk, component and software, including EAN 128 C#, GS1 128 .NET, GS1 128 Java, GS1 128 VB.NET, GS1 128 ASP.NET, GS1 128 Generator.

 

GS1 128 (UCC/EAN-128) Valid Data Scope

Android Barcode EAN 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 GS1 128 (UCC/EAN-128) barcodes in your Android application?

Generating barcode GS1 128 / EAN 128 in Java Class example

	EAN128 barcode = new EAN128();
	
	/*
	   GS1-128 / EAN-128 Valid data char set:
	        all 128 ASCII characters (Char from 0 to 127)
	
	   to encode Application Identifier (AI), add "()" around the AI code, and followed by the AI data
	   such as: (00)350123451234567894(21)01234567
	*/
	barcode.setData("(00)350123451234567894");
	
	//  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.
	barcode.setProcessTilde(true);
	
	// 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
	    */
	    RectF bounds = new RectF(30, 30, 0, 0);
	barcode.drawBarcode(canvas, bounds);
