It occurs NPE in invoking refreshUi() of AppButtonsPreferenceController when user fully install the instant app from google play and then directly open app info from the shortcut suggestion in launcher. Root cause: AppButtonsPreferenceController.refreshUi() will be invoked when user directly open app info from the shortcut suggestion in launcher. In refreshUi(), we will update the information of button preference, but the preferences will not be initialized if device existed an instant version for the app. Solution: Check button preference and initial them if need in refreshUi().
