  • Hi there, your Tutorial was fine! Wasnt that hard as i thought. I got a question about OneSignal.  Is it possible to use oneSignal for a Chat app, like whatsapp. Sending Notification when u got a new Message?
  • Hi, I have AndroidManifest, the documentation says Make your changes to Assets / Plugins / Android / AndroidManifest.xml instead. I did so but the manifest does not work (my application uses a connection to the Internet). how do I do it right? Sorry for my English )
