```
  - checkAuthorizationAsync
```
 abstract ListenableFuture<Status> checkAuthorizationAsync(int uid)
```
    Decides whether the given Android UID is authorized. (Validity is implementation dependent).
    As long as any given UID has active processes, this method should return the same value forthat UID. In order words, policy changes which occur while a transport instance is active, willhave no effect on that transport instance.
    
    Parameters:
    
    uid - The Android UID to authenticate.
