Android 设置logo上的badgenumber

Android 设置logo上的badgenumber

简介

在Android系统中，众所周知不支持BadgeNumber，虽然第三方控件BadgeView可以实现应用内的数字提醒，但对于系统的图标，特别是app的logo图标很难实现数字标志，好在小米，三星，索尼手机支持发送桌面快键提醒数字图标

}

注意lancherActivityClassName 必须被配置为 启动页对应得Activity
也就是包含<category android:name="android.intent.category.LAUNCHER" />的Activity
