* 针对国内支持的Launcher分别开发，支持为： * ** 常见机型及是否支持 * *** 华为 支持 * 小米 支持 * OPPO 可以支持但需要申请 * VIVO 不支持 * SAMSUNG 支持 * MEIZU 不支持 * google 8.0开始支持 显示一个点，长按点弹出数字
不造*不累赘叙述，直接封装
使用方法：
1.在使用之前首先 初始化 ，三个方法的参数分别是 应用包名/启动页的Activity及Context，四个参数的构造方法第三个是notification
DesktopCornerUtil.init("com.lonbon.nytest", "com.lonbon.view.activity.WelcomeActivity", BaseApplication.context);/** * 初始化 init 建议放在Application中执行 * t is recommended to execute in Application * * @param packageNameParameter @desc 应用包名 * @param mainActivityNameParameter @desc MainActivity * @param contextParameter @desc BaseApplication context */ public static void init(String packageNameParameter, String mainActivityNameParameter, Context contextParameter) { packageName = packageNameParameter; context = contextParameter; mainActivityName = mainActivityNameParameter; }
2.设置未读数量
DesktopCornerUtil.setBadgeNumber(1);注意的是：小米系统是自动会有的，且小米和三星系统 必须在后台设置才有效，前台设置无效，比如直接在前台时diamagnetic设置为10，那么不会显示，如果后台时收到通知会自动显示10
