Root Cause

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

generic

中文

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。

Workarounds

  1. 95% success Add tools:replace="android:icon" to the <application> tag in your main manifest to override library values 
    Add tools:replace="android:icon" to the <application> tag in your main manifest to override library values
  2. 90% success Use tools:node="merge" with tools:replace to handle multiple conflicting attributes 
    Use tools:node="merge" with tools:replace to handle multiple conflicting attributes
  3. 85% success Add tools:remove to exclude a conflicting attribute from a library manifest 
    Add tools:remove to exclude a conflicting attribute from a library manifest

中文步骤

  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

Dead Ends

Common approaches that don't work:

  1. 40% fail

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

  2. 50% fail

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

  3. 60% fail

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