PackageManager.getInstallerPackageName() 可以告诉我我的应用程序是从亚马逊应用商店安装的吗?

我计划在亚马逊应用商店和 Google Play 上发布我的应用，并且我的应用中有一些东西需要根据应用是否从亚马逊应用商店安装而略有不同.如果我正确理解了 PackageManager.getInstallerPackageName(String packageName) 方法，它会告诉我安装我的应用程序的应用程序的名称.对?如果是这样，如果我的应用是从亚马逊应用商店安装的，那么有人知道此方法返回的值是多少吗?如果不是，有谁知道我可以使用其他任何方法来确定我的应用是否是从亚马逊应用商店安装的?

I plan on publishing my app on Amazon app store as well as Google Play, and have some things in my app that need to behave slightly different depending on whether the app was installed from Amazon app store or not. If I understood the PackageManager.getInstallerPackageName(String packageName) method correctly, it tells me the name of the application that installed my app. Right? If so, does anyone know what the value returned by this method would be if my app was installed from Amazon app store? If not, does anyone know any other methods I can use to determine whether my app was installed from the Amazon app store?

注意:我知道关于 Stack Overflow 的其他问题已经得到回答，暗示使用PackageManager.getInstallerPackageName(String packageName) 到确定安装我的应用程序的应用程序的名称.然而，搜索 Stack Overflow 和其他地方，我一直无法确定返回的 valuePackageManager.getInstallerPackageName(String packageName) 将在如果应用是从亚马逊应用商店安装的.

Note: I am aware of other questions on Stack Overflow which have been answered alluding to the usage of PackageManager.getInstallerPackageName(String packageName) to determine the name of the application that installed my app. However, searching Stack Overflow and elsewhere, I have not been able to determine what the value returned by PackageManager.getInstallerPackageName(String packageName) would be in case the app was installed from the Amazon app store.
