java - java.lang.NullPointerException：当proguard启用时名称为空
问题描述
当我java.lang.NullPointerException: name is null在调试模式下启用 proguard 时，当我在没有 proguard 的情况下使用时，我的应用程序在调试 mmode 中运行良好。这是我用来启用 proguard 的片段
debug{
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
这是我得到的错误日志

解决方案
您可能需要添加此shrinkResources true
shin-code
资源收缩仅与代码收缩结合使用。在代码收缩器移除所有未使用的代码后，资源收缩器可以识别应用程序仍在使用哪些资源。当您添加包含资源的代码库时尤其如此 - 您必须删除未使用的库代码，以便库资源变得未被引用，因此可以被资源收缩器移除。
