I am new to Google Analytics.
I want to track my application by unique user id.
I am using `Google Analytics SDK for Android v3`.
I have this code on `onStart()`.I read about user id and created a new view for user tracking.

```
Tracker tracker = GoogleAnalytics.getInstance(this).getTracker("UA-xxx-2");
tracker.set(Fields.SCREEN_NAME, "Main Acitivty");
tracker.set("&uid", id);
tracker.send(MapBuilder.createAppView().build());

```

But I am not getting how can I get this uid in my Google Analytics Console,
I am trying to track user by their user\_id , so I can get complete report of particular user.
I am able to get count of the total active user , screens and hit events.
But I didn't get any success on getting the same report user-wise.
I also tried to create custom dimension and metrics but those are also not reflecting on account.I have no idea Where can I check this field.

For custom variables :

```
  easyTracker.send(MapBuilder
         .createAppView()
         .set(Fields.customDimension(1), "premiumUser")
        .build()
         );

```

I have searched , but I didn’t find any good tutorial on this.

Any help, suggestion , reference link would be greatly appreciated.
Thanks.
