No permission request at first start after install

Ionic Framework ionic-v3
1

Helle there,

my title says all.

I have created a blank app and added the device plugin.

constructor(private platform: Platform, public navCtrl: NavController, public device: Device)
{
	this.platform.ready().then((readySource) => {
		console.log(this.device.uuid);
    	});
}

After the installation, the uuid returns null, if i quit the app and open again, i asked fpr permissions to access the phone.
After grand the permission, the uuid returns correctly.

Steps:

  1. Install app
  2. Open app first time
  3. No permission request
  4. uuid = null
  5. quit app
  6. reopen app
  7. permission request opened
  8. uuid not null

Does anybody know this?

And at install, there is no permission listed.

maybe you have to add the permission to your android manifest manualy or sth. like that

Already done, has no effect.
