android - 区分APK文件？

Question

我有一个应用程序，我想为其分发免费和付费版本。但是，当我尝试在同一部手机上安装它们时，它们都注册为同一个应用程序。它们有不同的包名，所以我不知道如何区分它们以便它们可以作为两个应用程序安装。

当我签署它们时，它们也有完全不同的证书。

The Android SDK formally addresses the issue of a shared or common codebase with something called a library project.

Basically, the shared code is defined as a library project, then a paid and a free version are simply two different projects in your eclipse workbench, both referencing aforementioned library project.
