Hello, I am developing an Android app and I use AccessibilityService. In the method of onAccessibilityEvent I get the AccessibilityNodeInfo from the camera of the mobile and up there all right. Now I access the shutter button by findAccesibilityNodeInfoByViewId () and then I want to click on it with performAction (AccessibilityNodeInfo.ACTION_CLICK) but it does nothing. I have verified that isClickable () returns true so it should be able to click on it but it does not work, it does not give an error, it just does not do anything.
