如何知道，如果一个应用程序已经从谷歌播放或亚马逊下载？ [英] How to know if an app has been downloaded from Google Play or Amazon?

问题描述

有没有办法知道，如果一个应用程序已经从亚马逊或谷歌下载播放？我的应用程序，当然本身，在含义。

Is there any way to know if an application has been downloaded from Amazon or Google Play? I meant within the app itself, of course.

我已经部署了一个应用程序到两个站点，我宁愿想知道从那里得到了客户的应用程序中下载了它。我知道我可以部署不同的应用程序的每个服务，但这种广告能够避免，如果有某种方式一些维护工作，以解决它只是与应用程序内的条件使用相同的封装。

I have deployed an app to both sites and I rather like to know from where the customer has downloaded it within the application. I know I can deploy different applications to each service, but this ads some maintenance work that could be avoided if there were some manner to solve it just with a conditional within the app using the same package.

推荐答案

在code：

final PackageManager packageManager = getPackageManager();

try {
    final ApplicationInfo applicationInfo = packageManager.getApplicationInfo(getPackageName(), 0);
    if ("com.android.vending".equals(packageManager.getInstallerPackageName(applicationInfo.packageName))) {
        // App was installed by Play Store
    }
} catch (final NameNotFoundException e) {
    e.printStackTrace();
}

com.android.vending告诉你它从谷歌来了Play商店。我不知道亚马逊的Appstore是什么，但它应该很容易测试使用上述code。

"com.android.vending" tells you it came from the Google Play Store. I'm not sure what the Amazon Appstore is, but it should be easy to test using the above code.

通过ADB：

adb shell pm dump "PACKAGE_NAME" | grep "vending"

例：的

adb shell pm dump "com.android.chrome" | grep "vending"

installerPackageName=com.android.vending
