FYI, this test is based on CriteriaHelper, and is not in a good state. Can you
try to change this to CallbackHelper?

When we use CallbackHelper, we expect it should send notification if something
happens. In this test, we need to test the keyboard is not hidden. The problem
is, how do we test that nothing should happen? It seems not obvious, so I'll
keep using CriteriaHelper.

             @Override
             public boolean isSatisfied() {
                 InputConnection inputConnection = mTestContainerView.getContentViewCore()
                         .getImeAdapterForTest().getInputConnectionForTest();
                 return inputConnection != null;
             }
         });
     }
