在小米 三星 索尼 手机 ：图标上显示数字（未读消息数）：这部分代码，是从QQ5.0.apk中找的。
小米已经测试通过了，
三星和索尼的，由于没有相应的手机，没有测试，有的，可能修改一下代码（判断是什么手机的代码），
测试一下，可以在回复一下测试结果，谢谢
1.原生系统（原生的Launcher ）,只能修改快捷方式，增加和删除都会有toast提示
2.小米 三星 索尼 手机: 自定义的launcher: 发送显示未读消息数的action已经不同了。具体可以去看代码。。。
判断手机的代码：
public static void addNumShortCut(Context context,Class clazz,boolean isShowNum, String num, boolean isStroke)
{
Log.e(TAG, "manufacturer="+Build.MANUFACTURER);
if (Build.MANUFACTURER.equalsIgnoreCase("Xiaomi")){
//小米
xiaoMiShortCut(context, clazz, num);
}else if(Build.MANUFACTURER.equalsIgnoreCase("samsung")){
//三星
samsungShortCut(context, num);
}else {//其他原生系统手机
installRawShortCut(context, MainActivity.class, isShowNum, num, isStroke);
}
}
下面写好的工具类，上面的方法也在其中。
