| # Permitted Version Strings for Android 2.2 # | |
| As described in Section 3.2.2 of the [Android 2.2 Compatibility Definition](/cdds/android-2.2-cdd.pdf), | |
| only certain strings are allowable for the system property | |
| `android.os.Build.VERSION.RELEASE`. The reason for this is that | |
| applications and web sites may rely on predictable values for this string, and | |
| so that end users can easily and reliably identify the version of Android | |
| running on their devices. | |
| Because subsequent releases of the Android software may revise this string, | |
| but not change any API behavior, such releases may not be accompanied by a new | |
| Compatibility Definition Document. This page lists the versions that are | |
| allowable by an Android 2.2-based system. The only permitted values for | |
| `android.os.Build.VERSION.RELEASE` for Android 2.2 are: | |
| - 2.2 | |
| - 2.2.1 | |
