java.lang.RuntimeException: No activities found if calling check right after getActivity when test starts about android-test-kit

[GoogleCodeExporter]

I think there's a problem in this code, because this is where the exception was 
thrown
RootViewPicker

  private void waitForAtLeastOneActivityToBeResumed() {
    Collection<Activity> resumedActivities =
        activityLifecycleMonitor.getActivitiesInStage(Stage.RESUMED);
    if (resumedActivities.isEmpty()) {
      uiController.loopMainThreadUntilIdle();
      resumedActivities = activityLifecycleMonitor.getActivitiesInStage(Stage.RESUMED);
    }
    if (resumedActivities.isEmpty()) {
      List<Activity> activities = Lists.newArrayList();
      for (Stage s : EnumSet.range(Stage.PRE_ON_CREATE, Stage.RESTARTED)) {
        activities.addAll(activityLifecycleMonitor.getActivitiesInStage(Stage.RESUMED));
      }
      if (activities.isEmpty()) {
        throw new RuntimeException("No activities found. Did you forget to launch the activity "
            + "by calling getActivity() or startActivitySync or similar?");
      }

When there's no activity in resumed state, it tries to find all activities in 
other states. However, when calling to the activitymonitor, it still passes 
Stage.RESUME in. It should be:
      for (Stage s : EnumSet.range(Stage.PRE_ON_CREATE, Stage.RESTARTED)) {
        activities.addAll(activityLifecycleMonitor.getActivitiesInStage(s));
      }

There's another problem in the method:

      for (int waitIdx = 0; waitIdx < waitTimes.length; waitIdx++) {
        Log.w(TAG, "No activity currently resumed - waiting: " + waitTimes[waitIdx]
            + "ms for one to appear.");
        uiController.loopMainThreadForAtLeast(waitTimes[waitIdx]);
        resumedActivities = activityLifecycleMonitor.getActivitiesInStage(Stage.RESUMED);
        if (!resumedActivities.isEmpty()) {
          break;
        }
      }
      throw new RuntimeException("No activities in stage RESUMED. Did you forget to launch the "
          + "activity. (test.getActivity() or similar)?");

Even if it gets the resumed activities in the for loop, it will still throw the 
exception. It should be 

if(resumedActivities.isEmpty())
{
      throw new RuntimeException("No activities in stage RESUMED. Did you forget to launch the "
          + "activity. (test.getActivity() or similar)?");
}

I confirm that the issue still occurs on Espresso 2.0. Marking this as FIXED 
seems premature to me.

getActivity() cause app crash.

it mention about attempt to invoke virtual method.

Still having this issue. Is there a workaround ?
