Grant Permissions Rule errors out while connecting to UiAutomation

I keep getting these errors for few of my automation tests. Most of the times, on re-running the tests, it works fine again

```

```

I am granting permissions in the following manner

```
public GrantPermissionRule grantPermissionRule = GrantPermissionRule.grant(Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_PHONE_STATE, Manifest.permission.READ_EXTERNAL_STORAGE);
```

Any help in this regards will be appreciated.

Start by reproducing the intermittent failure around GrantPermissionRule.grantPermissions and the UiAutomation.connect stack trace, using the permission declaration shown in the issue. Trace the call from BaseTest.java:40 through PermissionRequester and UiAutomationShellCommand, then determine why rerunning sometimes succeeds. Done means the cause is established and the permission setup no longer intermittently fails.
