Android 在应用图标上设置未读消息数量

* 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

不造轮子不累赘叙述,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
