title: how to allow autostart permission like whatapp app for ionic application
body: <p>I have an application developed with ionic now I have a problem when starting the device for some phone notifications do not arrive until I open the application. I debug the application with android studio I found that the device receives the notification but the system does not allow the reception of notifcations because the application is not allowed after the boot to start; you have to go to the settings to allow the application to run to receive notifications in background.My question is how I can allow the application with ionic to have permission to do the autostart after the boot as c is the case of whatsapp. If there is also with android it's welcome</p>
