The paper says droidbot using UI Automator or Hierarchy Viewer to dump UI hierarchy tree, however I can only find AccessibilityService in droidbot apk. I am confused about this. Can you give an explanation?

Hi, DroidBot used viewclient (based on UI Automator and Hierarchy Viewer) to obtain UI hierarchy at first. In commit 323e37e we introduced droidbotApp, which uses AccessibilityService to fetch UI structure from the Android client. Then we found droidbotApp can completely replace the previous method with better performance and robustness, so we removed viewclient in commit d9587f9.
