Question

The method for kiosking an application by disabling pull and click of the status bar does not work on android 8. As anserwed on How to disable status bar click and pull down in Android? .

I have tested it on android 7 and less and it works, but the status bar still pulls down when pulled on android 8.

I didnt find any solution for the same. Please let me know if there is any solution that works for oreo also.

Thanks!

I am using below code in MainActivity .

//Global Declaration
Handler collapseNotificationHandler;

@Override
    public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    Log.d(tag, "window focus changed");

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        collapseNow();
    }
}

Collapse Method

public void collapseNow() {

    try {
        // Initialize 'collapseNotificationHandler'
        if (collapseNotificationHandler == null) {
            collapseNotificationHandler = new Handler();
        }

        // Post a Runnable with some delay - currently set to 300 ms
        collapseNotificationHandler.postDelayed(new Runnable() {

            @Override
            public void run() {

                // Use reflection to trigger a method from 'StatusBarManager'
                Object statusBarService = getSystemService("statusbar");
                Class<?> statusBarManager = null;

                try {
                    statusBarManager = Class.forName("android.app.StatusBarManager");
                } catch (ClassNotFoundException e) {
                    e.printStackTrace();
                }

                Method collapseStatusBar = null;
                try {
                    // Prior to API 17, the method to call is 'collapse()'
                    // API 17 onwards, the method to call is `collapsePanels()`
                    if (Build.VERSION.SDK_INT > 16) {
                        collapseStatusBar = statusBarManager.getMethod("collapsePanels");
                    } else {
                        collapseStatusBar = statusBarManager.getMethod("collapse");
                    }
                } catch (NoSuchMethodException e) {
                    e.printStackTrace();
                }

                collapseStatusBar.setAccessible(true);

                try {
                    collapseStatusBar.invoke(statusBarService);
                } catch (IllegalArgumentException e) {
                    e.printStackTrace();
                } catch (IllegalAccessException e) {
                    e.printStackTrace();
                } catch (InvocationTargetException e) {
                    e.printStackTrace();
                }
                // Currently, the delay is 10 ms. You can change this
                // value to suit your needs.
                collapseNotificationHandler.postDelayed(this, 10L);
            }
        }, 10L);
    } catch (Exception e) {
        e.printStackTrace();
    }
}
