开发移动与穿戴应用时添加Vokaturi遭遇Manifest合并错误求助

这是典型的Android Manifest合并冲突问题，我来帮你快速搞定：核心原因是你引入的OpenVokaturi-3-0-android.aar库的Manifest文件已经定义了android:theme="@style/AppTheme"，而你的wear模块自身的Manifest又指定了@android:style/Theme.DeviceDefault，两个相同属性冲突导致编译失败。

具体修复步骤 #

按照错误提示的建议，只需要修改wear模块的AndroidManifest.xml即可：

1. 首先在根manifest标签中添加tools命名空间（如果还没添加的话）：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="chun.emotionsensor">

2. 找到application标签，添加tools:replace="android:theme"属性，强制用你的wear模块主题覆盖库中的主题：

<application
    android:theme="@android:style/Theme.DeviceDefault"
    <!-- 你的其他application属性 -->
    tools:replace="android:theme">

补充说明 #

如果后续遇到其他Manifest属性冲突（比如android:label、android:icon等），可以在tools:replace中用逗号分隔多个属性，例如：

tools:replace="android:theme,android:label"

你提供的错误信息 #

Error:Execution failed for task ':wear:processDebugManifest'.
Manifest merger failed : Attribute application@theme value=(@android:style/Theme.DeviceDefault) from AndroidManifest.xml:15:9-59 is also present at [:OpenVokaturi-3-0-android:] AndroidManifest.xml:17:9-40 value=(@style/AppTheme). Suggestion: add 'tools:replace="android:theme"' to element at AndroidManifest.xml:10:5-36:19 to override.
