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：

/**** 在应用图标的快捷方式上加数字* @param clazz 启动的activity* @param isShowNum 是否显示数字* @param num 显示的数字：整型* @param isStroke 是否加上边框* */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。
