即使在实施 ngCordova（cordova-plugin-badge）和 phonegap-plugin-push 之后，Android 的应用程序图标上的徽章也不会显示

Question

如果有人能帮我解决这个困扰我好几天的问题，我将不胜感激。

我有一个使用 Ionic 框架创建的混合应用程序，我已经在其上实现了推送通知（通过 phonegap-plugin-push）。推送通知工作正常，但我想要的是推送通知（即 GCM 有效负载）将徽章 count/number 发送到应用程序，应用程序将接受该 count/number 并将其显示为应用程序图标旁边的徽章。考虑到徽章已经内置，我的代码非常适合 iOS 设备，但我很难在 Android 平台上实现相同的想法（徽章）。

我知道由于 Android 平台未内置徽章，某些设备可能不受支持，但至少我希望它适用于某些设备（即三星、索尼）。我做了很多研究，最突出的是：

cordova-plugin-badge (https://github.com/katzer/cordova-plugin-badge) 文档中所述 supposed 同时适用于 iOS 和某些Android 台设备，但它对我来说根本无法在任何 Android 台设备上运行。请注意，我一直在测试的 Android 设备是来自 Genymotion 的模拟器，我已经在其上设置了 Google Play Services 并且能够接收推送通知并且功能几乎与真实设备一样设备，这会成为问题吗？
ShortcutBadger (https://github.com/leolin310148/ShortcutBadger) 仅包含 native Android 实现的文档，据称被 cordova-plugin-badge 用作上面说要扩展对混合 Android 应用程序的支持，但这根本无法帮助我。

        }

        $scope.decrease = function() {
          console.log("inside decrease");
          $cordovaBadge.hasPermission().then(function(result) {
              $cordovaBadge.decrease();
              window.alert("Good job!");

              console.log(JSON.stringify(error));   // display error message
          });
        }
    });
});

此外，问题是 app 图标 必须转换为 widget 才能使徽章起作用吗？我不确定 cordova-plugin-badge 是如何实现的，并且说明中没有说明 Android.

需要的小部件

谢谢您，任何 help/tips 不胜感激 :) 我已经解决这个问题好几天了，这很令人沮丧。

Stock Android 目前在标准启动器上不提供此功能。

某些制造商（尤其是三星）已将此功能包含在他们定制的 Android 启动器中。还有一些第 3 方启动器（例如 Nova Launcher）包含一个 API 来完成这个。
