以编程方式确定应用程序是否为 MarketPlace 版本
我有一个在 MarketPlace 内外提供的应用程序。
有没有办法从代码中确定应用程序来自哪里？
我有一些间接方法...
1）我可以简单地从它们是否勾选了“允许安装非市场应用程序”来推断...
2）或者我可以单独制作构建并在代码中明确它。
I have an application that's offered in and outside of the MarketPlace.
Is there a way of determining from within the code where the application came from?
I've got a few indirect methods ...
1) I could simply infer from whether they have "Allow installation of non-Market applications" ticked ...
2) Or I could just make separate builds and make it explicit in the code.

如果
PackageManager.getInstallerPackageName ()为您的应用程序返回com.google.android.feedback，然后该应用程序由 Android Market 安装。If
PackageManager.getInstallerPackageName()returnscom.google.android.feedbackfor your application, then it was installed by the Android Market.在每个版本的
android:versionName中明确说明。如果代码可供人们编译自己的 APK，请将
android:versionName设置为“自定义”，并在为市场构建时临时更改它。Make it explicit in the
android:versionNameof each release.And if the code is available for people to compile their own APKs, set the
android:versionNameto "custom" and just change it temporarily when building for the Market.鉴于当您擦除应用程序的缓存时，市场应用程序甚至不知道应用程序来自何处，我非常怀疑是否有任何其他方法可以找到答案。
Given that the Market application won't even know where an application came from when you wipe its cache, I very much doubt there is any other way to find out.
