我在构建中包含以下内容：

I've included the following in my build:

android {
    buildTypes {
        release {
            multiDexKeepProguard file ('multidex-keep.pro')
        }
    }
}

multidex-keep.pro：

multidex-keep.pro:

-keep class io.org.app.ui.main.** { *; }
-keep class io.org.app.ui.loading.** { *; }

推荐答案

看起来像类 io.org.app.ui.loading.LoadingFragment 是通过反射加载的，但是您的proguard文件不会阻止对该类进行混淆，因此已对其进行了重命名，这说明了为什么不能这样做

It looks like the class io.org.app.ui.loading.LoadingFragment is loaded by reflection, but your proguard file doesn't prevent that class from being obfuscated, so it has been renamed which explains why it can't be found.

我想在本地部署应用程序的发行版时应该会遇到相同的错误。

I imagine you should get the same error when you deploy the release version of your app locally.

尝试调整proguard文件以防止该类重命名。

Try tweaking the proguard file to prevent the renaming of that class.
