Android系统 小米，三星，索尼手机发送桌面快键提醒数字图标，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，即使是绘图的方式不断修改，但这种方式天生弊端，实用性很差。但幸运的是，某些ROM厂商提供了私有的API，但也带来了难度，API的不同意意味着代码量的增加和兼容性问题更加突出。
我们现在来实现桌面logo或者说icon右上角的图标，先来看2张图，第一张来自互联网，第二张来自个人实践！（由于实验条件有限，只能测试小米的(⊙o⊙)…，有兴趣的同学测试一下其他的吧）
好了，上代码
