当我尝试通过此命令构建项目时发生此错误

flutter build apk --split-per-abi

我不知道那是什么？ 请帮忙。

Answer 1

构建器优化应用程序中的图像，在本例中为 png 图像。这是为了减小apk的大小。对于您的情况，它无法这样做。要在不进行优化的情况下运行，您可以将以下内容放入您的 build.gradle

android {
buildTypes {
    release {
        crunchPngs false // or true
    }
  }
}

Answer 2

我将 res/drawable 中的 .png 文件更改为 .jpg，它对我有用

Answer 3

在 buildtypes 版本中添加“crunchPngs false”解决了我的问题
