How to count newUsers per device ? Google Analytic

问题:

I am using google analytics in my ios/android apps.

I need to count the following:

1. new downloads : when user download the application from the store for the first time.
2. reDownload : when user download the application from the store after uninstalling it.

---

here is an example:

when "user A" download the application from the store for the first time then it count as new download.

when "user A" delete the application then after some time "user A" download the application again from the store , this count as reDownload.

---

please note:

newUsers metric count new downloads + reDownload together. because every time the user install the application google sdk create new user.

---

my solution:

ios / android has a unique advertisinId which is constant and doesn't change regularly .

so i would create a custom dimension called advertisinId with user level scope .

and then i need to create two custom metric:

1. first one which is count unique advertisinId
2. second one which is count advertisinId who has more than one user.

How to do build those metrics ?

Thanks

You don't really need Google Analytics for this, when you upload your app on the Play Store, you are able to get all that information, plus much more:
