Auto click android

Do I need to auto click the "Start now" button or make this request only accepted once. How can I do this? I'm trying through the click with accessibility option. But how to do the click I don't know.

public class MyAccessibilityService extends AccessibilityService {

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {

        Log.e("TAG", "onAccessibilityEvent.....................................");

    }

    @Override
    public void onInterrupt() {
        Log.e("TAG", "onInterrupt.....................................");
    }


    @Override
    protected void onServiceConnected() {
        super.onServiceConnected();

        Log.e("TAG", "onServiceConnected.....................................");

        AccessibilityServiceInfo info = new AccessibilityServiceInfo();

        info.eventTypes = AccessibilityEvent.TYPE_VIEW_CLICKED | AccessibilityEvent.TYPE_VIEW_FOCUSED;

        info.feedbackType = AccessibilityServiceInfo.FEEDBACK_SPOKEN;
        info.notificationTimeout = 100;
        this.setServiceInfo(info);

    }
}
