解决android通知被禁用toast无法显示问题，参照NotificationManagerService编写,支持自定义view,兼容toast所有方法。

dependencies { compile 'com.github.huize303:simpletoast:1.1' }

Application onCreate 加入

registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {

    @Override
          public void onActivityPaused(Activity activity) {
              NotificationManagerService.getInstance().clearNotifications(activity);
          }
}
