Android application(.apk files) updating for an existing app in Google play
<p>At present I am having four .apk files for an android application with different version code and version 1.0 . Now I want to update my app with same four .apk files but there are now some changes in the manifest file for each apk. I a using same certificate key(existing one) and different version code with 1.1 version for each updated .apk file.</p>

<p><strong>Now in my Google play account for that app, existing four apk are there in active mode. Now when I will upload my updated four apks, I have to activate them too. But my question is that should I deactivate the older ones or leave them as it is ????</strong> </p>

<p><strong><em>Bcoz previously I used :</em></strong>  </p>

<pre><code>android:minSdkVersion="7"
android:targetSdkVersion="16"
</code></pre>

<p><strong><em>Now using:</em></strong>   </p>

<pre><code> android:minSdkVersion="8"
 android:targetSdkVersion="16" 
</code></pre>
