Android API Difference between 3.0 and 4.0 OS - Ice Cream Sandwich

API Difference between Honeycomb and Ice Cream Sandwich

The overall difference between API Levels 13 and 14 is approximately 3.95%. The table below lists the numbers of program elements (packages, classes, constructors, methods, and fields) that were added, changed, or removed. The table includes only the highest-level program elements — that is, if a class with two methods was added, the number of methods added does not include those two methods, but the number of classes added does include that class.

Type	Additions	Changes	Removals	Total
Packages	5	48	0	53
Classes and Interfaces	90	192	0	282
Constructors	19	2	0	21
Methods	265	94	29	408
Fields	405	34	16	455
Total	804	370	45	1219
