Permitted version strings for Android 4.1

As described in Section 3.2.2 of the Android 4.1 Compatibility Definition, 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 4.1-based system. The only permitted values for android.os.Build.VERSION.RELEASE for Android 4.1 are:

  • 4.1

  • 4.1.1
