+page.title=Permitted Version Strings for Android 2.3
+doc.type=compatibility
+@jd:body
+<p>As described in Section 3.2.2 of the <a
+href="{@docRoot}compatibility/android-2.3-cdd.pdf">Android 2.3 Compatibility
+Definition</a>, only certain strings are allowable for the system property
+<code>android.os.Build.VERSION.RELEASE</code>. 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.</p>
+<p>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.</p>
+<p>The value of <code>android.os.Build.VERSION.RELEASE</code> for Android 2.3
+MUST be one of the following strings:</p>
+<ul>
+<li>2.3</li>
+<li>2.3.1</li>
+</ul>
