Google play shows error code 504 for Android N preview
<p>I developed an app and published it on the <code>Play store</code>, but some users experienced problem with install from store. <code>They get an error code 504 during installation.</code> The problem occurs only on <code>Android N</code> devices. Does anybody has same issue?</p>

<p>UPDATE:</p>

<p>After install <code>Android N</code> device gives me this log error:</p>
