根因分析

同一属性（例如 android:icon）在多个合并的清单文件中定义且值冲突，导致合并冲突。

English

The same attribute (e.g., android:icon) is defined in multiple merged manifest files with conflicting values, causing a merge conflict.

解决方案

  1. 在主清单的 <application> 标签中添加 tools:replace="android:icon" 以覆盖库的值
  2. 使用 tools:node="merge" 配合 tools:replace 处理多个冲突属性
  3. 添加 tools:remove 以排除来自库清单的冲突属性

无效尝试

常见但无效的做法:

  1. 40% 失败

    Removing may cause missing icon if it's required; better to use tools:replace to override.

  2. 50% 失败

    If the manifests come from libraries, you may not have direct control over them.

  3. 60% 失败

    tools:remove deletes the attribute entirely, which may not be desired.
