Clear Notifications

@gilb i do it manually with:

    public void clearNotifications(AndroidDriver driver) {
        System.out.println("  clearNotifications()");
        driver.openNotifications();
        nativeNotificationPage = new NativeNotificationPage(driver);
        assertTrue("Native notification page is NOT loaded", nativeNotificationPage.isNativeNotificationPage());
        if (nativeNotificationPage.isClearAllBtnLoaded()) {
            nativeNotificationPage.tapClearAllBtn();
        } else {
            ((AndroidDriver) driver).pressKeyCode(AndroidKeyCode.BACK);
            sleep(1);
        }
        System.out.println("  notifications cleared");
    }

where Notification Page is (you can take all locators or use it as is):

public class NativeNotificationPage extends Page {

    @AndroidFindBy(id= "com.android.systemui:id/notification_panel")
    private List<AndroidElement> notificationPanel;
    //settings data
    @HowToUseLocators(androidAutomation = LocatorGroupStrategy.ALL_POSSIBLE)
    @AndroidFindBy(id = "com.android.systemui:id/clear_all_button")
    @AndroidFindBy(id = "com.android.systemui:id/dismiss_text")
    private List<AndroidElement> clearAllBtn;


    public NativeNotificationPage(WebDriver driver) {
        super(driver);
    }

    public boolean isNativeNotificationPage() {
        System.out.println("  check 'Notification' Screen loaded");
        return  !notificationPanel.isEmpty();
    }

    public boolean isClearAllBtnLoaded() {
        return !clearAllBtn.isEmpty();
    }

    public boolean tapClearAllBtn() {
        return tapElementInList_Android(clearAllBtn, 0);
    }

}
