The reason for this is that 22 applications and web sites may rely on predictable values for this string, and 23 so that end users can easily and reliably identify the version of Android 24 running on their devices. 25 26 Because subsequent releases of the Android software may revise this string, 27 but not change any API behavior, such releases may not be accompanied by a new 28 Compatibility Definition Document. This page lists the versions that are 29 allowable by an Android 2.1-based system. The only permitted values for 30 `android.os.Build.VERSION.RELEASE` for Android 2.1 are: 31 32 - 2.1 33 34 - 2.1-update1 35 36
