How can I programmatically expand status bar on samsung lollipop devices?

Question

I use this code to expand status bar:

Object sbservice = getSystemService( "statusbar" );
Class<?> statusbarManager = Class.forName( "android.app.StatusBarManager" );
Method showsb;
if (Build.VERSION.SDK_INT >= 17) {
    showsb = statusbarManager.getMethod("expandNotificationsPanel");
} 
else { 
    showsb = statusbarManager.getMethod("expand");
} 
showsb.invoke( sbservice );

With permission:

 <uses-permission android:name="android.permission.EXPAND_STATUS_BAR" />

It work well exept with the samsung lollipop device nothing happen. Does anyone know how to expand status bar on samsung lollipop device? Thanks!

Can you answer this question based on accessibility service https://stackoverflow.com/q/49734263/4813904 — Siva, Apr 10 '18 at 06:46

Finally I found it but I need to use the Accessibility service:

public class MyAccessibilityService extends AccessibilityService {
@Override
public void onAccessibilityEvent(AccessibilityEvent event) {
    Log.e("MyAccessibilityService", "get event");
    if (event.getEventType() == AccessibilityEvent.TYPE_TOUCH_INTERACTION_END) {
        switch (event.getAction()) {
            case 1:
                Log.e("MyAccessibilityService ", "home");
                performGlobalAction(AccessibilityService.GLOBAL_ACTION_HOME);
                break;
            case 2:
                Log.e("MyAccessibilityService ", "back");
                performGlobalAction(AccessibilityService.GLOBAL_ACTION_BACK);
                break;
            case 3:
                Log.e("MyAccessibilityService ", "power");
                performGlobalAction(AccessibilityService.GLOBAL_ACTION_POWER_DIALOG);
                break;
            case 4:
                Log.e("MyAccessibilityService ", "noti");
                performGlobalAction(AccessibilityService.GLOBAL_ACTION_NOTIFICATIONS);
                break;

        }


    }
}

Fire even:

AccessibilityEvent event1 = AccessibilityEvent.obtain(AccessibilityEvent.TYPE_TOUCH_INTERACTION_END);
        event1.setClassName(className);
        event1.getText().add("noti");
        event1.setAction(4);
        event1.setPackageName(packageName);
        event1.setEnabled(true);
        AccessibilityManager manager = (AccessibilityManager)context.getSystemService(Context.ACCESSIBILITY_SERVICE);
        AccessibilityRecordCompat recordCompat = AccessibilityEventCompat.asRecord(event1);
        recordCompat.setSource(v);
        if (Utility.isAccessibilityEnable(context)) {
            manager.sendAccessibilityEvent(event1);
        }

Does it works on latest Android version and all other devices?? — Siva, Apr 01 '18 at 02:14
@SivaKReddyCShiva I think it still does. The Accessibility service does not change much. — Hai nguyen thanh, Apr 02 '18 at 01:40
Thanks for the reply.. Is it possible to take screenshots after expanding the status bar — Siva, Apr 02 '18 at 01:42
