OneSignal creating multiple user records for each app installation
<p>I shifted from <strong>parse.com</strong> to <strong>oneSignal</strong> for push notification service.
I integrated the SDK into my android app and it is able to create <strong>a user record</strong> in oneSignal, when the application is installed.
But when I uninstall and re-install my android app, a new user record is created in oneSignal, resulting in duplicate user records.</p>

<p>How do I over come this issue of duplication? I want only one user record even if the user reinstalls my application. </p>

<p>In parse.com I use to check at the parse cloud code for duplicates before inserting new records .. any thing similar at oneSignal ?</p>
