Android plugin is too old (2.4.0-alpha7) : <p>I'm using android studio 2.4, And getting this error. Apparently I have to update my android plugin, but when I checked jcenter for new versions the only version 
available was <strong>2.5.0-alpha-preview-02</strong>. which would cause the exact same error. 
I also see somewhere in the error message that it says I must replace the <code>ANDROID_DAILY_OVERRIDE</code> environment variable. But I really have no idea where to put this environment variable? Should it go to local.properties or is it an OS env variable? I was wondering if anybody else is facing this problem.</p>

<p>This is the full message</p>

<pre><code>Error:(1, 0) The android gradle plugin version 2.5.0-alpha-preview-02 is too old, please update to the latest version.
