android - WearOS 打包：程序类型已经存在：.BuildConfig

问题描述

按照说明构建包含嵌入式 Wear apk 的应用程序的签名版本，我不断遇到错误：

Error: Program type already present: com.socialstepsapp.socialsteps.BuildConfig

在搜索完 SO 后，我得出结论，由于我的 Wear 模块与我的主应用程序模块具有相同的包名，所以有些事情失败了。但据我从文档中了解，这正是我应该做的。

我已将其包含在我的主要项目中：

wearApp project(':wear')

完整的堆栈跟踪很长：

我不确定如何解决这个问题以构建嵌入式 Wear 应用程序。

标签： androidwear-os

解决方案

我在同一个问题上徘徊了几天......最后两者似乎都是真的 - 你必须有不同的包名，但两个 apk 必须有相同的包名......

诀窍是，apk 文件的包名由 build.gradle 文件的 applicationid 定义。所以这在所有模块中必须相同。模块的包名称可以在清单中更改（作为清单标签的属性），并且每个模块的这些名称可能不同。

让我知道这是否对您也有帮助！
