Codenames, Tags, and Build Numbers

At a high level, Android development happens around families of releases, which use code names ordered alphabetically after tasty treats.

Platform code names, versions, API levels, and NDK releases

The code names match the following version numbers, along with API levels and NDK releases provided for convenience:

Code name	Version	API level
(no code name)	1.0	API level 1
(no code name)	1.1	API level 2
Cupcake	1.5	API level 3, NDK 1
Donut	1.6	API level 4, NDK 2
Eclair	2.0	API level 5
Eclair	2.0.1	API level 6
Eclair	2.1	API level 7, NDK 3
Froyo	2.2.x	API level 8, NDK 4
Gingerbread	2.3 - 2.3.2	API level 9, NDK 5
Gingerbread	2.3.3 - 2.3.7	API level 10
Honeycomb	3.0	API level 11
Honeycomb	3.1	API level 12, NDK 6
Honeycomb	3.2.x	API level 13
IceCreamSandwich	4.0.1 - 4.0.2	API level 14, NDK 7
IceCreamSandwich	4.0.3	API level 15

Starting with Cupcake, individual builds are identified with a short build code, e.g. FRF85B.

The first letter is the code name of the release family, e.g. F is Froyo.

The second letter is a branch code that allows Google to identify the exact code branch that the build was made from, and R is by convention the primary release branch.

The next letter and two digits are a date code. The letter counts quarters, with A being Q1 2009. Therefore, F is Q2 2010. The two digits count days within the quarter, so F85 is June 24 2010.

Finally, the last letter identifies individual versions related to the same date code, sequentially starting with A; A is actually implicit and usually omitted for brevity.

The date code is not guaranteed to be the exact date at which a build was made, and it is common that minor variations added to an existing build re-use the same date code as that existing build.

Source code tags and builds

Starting with Donut, the exact list of tags and builds is in the following table:

Build	Tag	Notes

ESE81	android-2.1_r2.1s

GRH55	android-2.3_r1	earliest Gingerbread version, Nexus S
GRH78	android-2.3.1_r1	Nexus S
GRH78C	android-2.3.2_r1	Nexus S
GRI40	android-2.3.3_r1	Nexus One, Nexus S
GRI54	android-2.3.3_r1.1	Nexus S
GRJ06D	android-2.3.4_r0.9	Nexus S 4G
GRJ22	android-2.3.4_r1	Nexus One, Nexus S, Nexus S 4G
GRJ90	android-2.3.5_r1	Nexus S 4G
GRK39C	android-2.3.6_r0.9	Nexus S
GRK39F	android-2.3.6_r1	Nexus One, Nexus S
GWK74	android-2.3.7_r1	latest Gingerbread version, Nexus S 4G
ITL41D	android-4.0.1_r1	earliest IceCreamSandwich version, Galaxy Nexus
ITL41D	android-4.0.1_r1.1	Galaxy Nexus
ITL41F	android-4.0.1_r1.2	Galaxy Nexus
ICL53F	android-4.0.2_r1	Galaxy Nexus
IML74K	android-4.0.3_r1	Nexus S
IML77		latest IceCreamSandwich version

The branches froyo, gingerbread, ics-mr0, ics-mr1, represent development branches that do not exactly match configurations that were tested by Google. They might contain a variety of changes in addition to the official tagged releases, and those haven't been as thoroughly tested.

Honeycomb GPL modules

For Honeycomb, the entire platform source code isn't available. However, the parts of Honeycomb licensed under the GPL and LGPL are available under the following tags:

Build	Tag	Notes
HRI39	android-3.0_r1	earliest Honeycomb version
HRI66	android-3.0_r1.1
HWI69	android-3.0_r1.2
HRI93	android-3.0_r1.3
HMJ37	android-3.1_r1
HTJ85B	android-3.2_r1
HTK55D	android-3.2.1_r1
HTK75D	android-3.2.1_r2
HLK75C	android-3.2.2_r1
HLK75D	android-3.2.2_r2
HLK75F	android-3.2.4_r1	latest Honeycomb version

There is no manifest that contains exactly those. However, there are manifests that allow building those components. The following commands work for 3.0_r1.1, and using other versions can be done by switching the git checkout paramater, and if necessary the -m parameter in repo init. The git checkout command outputs an error for the non-GPL projects, where it can't find the tag in question.
