1page.title=Permitted Version Strings for Android 4.4 2@jd:body 3 4<p>As described in Section 3.2.2 of the <a 5href="/compatibility/android-4.4-cdd.pdf">Android 4.4 Compatibility Definition</a>, 6only certain strings are allowable for the system property 7<code>android.os.Build.VERSION.RELEASE</code>. The reason for this is that 8applications and web sites may rely on predictable values for this string, and 9so that end users can easily and reliably identify the version of Android 10running on their devices.</p> 11<p>Because subsequent releases of the Android software may revise this string, 12but not change any API behavior, such releases may not be accompanied by a new 13Compatibility Definition Document. This page lists the versions that are 14allowable by an Android 4.4-based system. The only permitted values for 15<code>android.os.Build.VERSION.RELEASE</code> for Android 4.4 are:</p> 16<ul> 17<li>4.4</li> 18<li>4.4.1</li> 19<li>4.4.2</li> 20<li>4.4.3</li> 21<li>4.4.4</li> 22</ul> 23
