Click on the Notification programmatically

问题:

I trying click on the notification after receiving it.

I'm able to drag the notification drawer using the Accessibility service.

For clicking the notification I'm using accessibilityEvent.getSource() and accessibilityNodeInfo.performAction(AccessibilityNodeInfo.ACTION_CLICK);

My code:

public class MyAccessibilityService extends AccessibilityService {  /**  * On receiving the AccessibilityEvent performs the Actions  *  * @param event  */ @Override public void onAccessibilityEvent(AccessibilityEvent event) {     Log.i(TAG, "Get the Accessibility Event");     if (event.getEventType() == AccessibilityEvent.TYPE_TOUCH_INTERACTION_END) {         handleTypeTouchInteractionEndEvents(event);     }     if (event.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED) {         handleTypeWindowStateChangedEvents(event);     } }  @Override public void onServiceConnected() {     AccessibilityServiceInfo accessibilityServiceInfo = new AccessibilityServiceInfo();     accessibilityServiceInfo.eventTypes = AccessibilityEvent.TYPE_TOUCH_INTERACTION_END | AccessibilityEvent.TYPE_VIEW_CLICKED |             AccessibilityEvent.TYPE_VIEW_FOCUSED | AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED | AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED;     accessibilityServiceInfo.feedbackType = AccessibilityServiceInfo.CAPABILITY_CAN_PERFORM_GESTURES;     accessibilityServiceInfo.flags = AccessibilityServiceInfo.DEFAULT | AccessibilityServiceInfo.FLAG_RETRIEVE_INTERACTIVE_WINDOWS;     accessibilityServiceInfo.notificationTimeout = NOTIFICATION_TIME_OUT;     this.setServiceInfo(accessibilityServiceInfo); }  @Override public void onInterrupt() {     //Do Nothing }  /**  * Performs the action for TYPE_TOUCH_INTERACTION_END events  *  * @param accessibilityEvent  */ private void handleTypeTouchInteractionEndEvents(AccessibilityEvent accessibilityEvent) {     switch (accessibilityEvent.getAction()) {         case EXPAND_NOTIFICATIONS_DRAWER:             Log.i(TAG, "perfroming expand notification bar");         performGlobalAction(AccessibilityService.GLOBAL_ACTION_NOTIFICATIONS);             break;         default:             Log.i(TAG, "Event type not defined");     } }  private void handleTypeWindowStateChangedEvents(AccessibilityEvent accessibilityEvent) {     switch (accessibilityEvent.getAction()) {         case ACTION_CLICK:             Log.i(TAG, "Performing click Action");             findNotificationIconAndClick("com.my.app:id/notification_icon", accessibilityEvent);             Log.i(TAG, "Click Action is successfull");         default:             Log.i(TAG, "Event type not defined");     } }   public void findNotificationIconAndClick(String id, AccessibilityEvent accessibilityEvent) {     AccessibilityNodeInfo accessibilityNodeInfo = accessibilityEvent.getSource();     List<AccessibilityNodeInfo> nodeInfoList = accessibilityNodeInfo.findAccessibilityNodeInfosByViewId(id);     if (nodeInfoList != null && !nodeInfoList.isEmpty()) {         for (AccessibilityNodeInfo nodeInfo : nodeInfoList) {             if (nodeInfo != null) {                 performClick(nodeInfo);                 break;             }         }     } } }

I'm new to using accessibility service. Can someone tell me if there is any mistake from my side or if it is not possible to click on a notification using accessibility service? Are there any other possibilities without using Accessibility Service to click on the Notification?
