| # 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 (incl. 2.1-update 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 - 2.3.4 | API level 10 |
| Honeycomb | 3.0 | API level 11 |
| Honeycomb | 3.1 | API level 12 |
| |
| 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 |

| GRJ06D | android-2.3.4_r0.9 | Nexus S 4G |
| GRJ22 | android-2.3.4_r1 | latest Gingerbread version, Nexus One, Nexus S, Nexus S 4G |
| |
| The branches donut, eclair, froyo, gingerbread 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: |
