ResourceContainer.getImageByFileName extension is not compatible with isMinifyEnabled = true on Android

[epicarchitect]

ResourceContainer.getImageByFileName(fileName: String) cannot find image by name when isMinifyEnabled = true in build.gradle.

The function works fine when the source code is not changed (when isMinifyEnabled = false). However, when isMinifyEnabled = true, the names of variables in the MR class are changed and getImageByFileName(fileName) returns null.

Thanks for report! Maybe you have ideas how it can be fixed?

Here's my workaround:

fun getImageByFileName(fileName: String) = ImageResource(
        context.resources.getIdentifier(
                fileName.toLowerCase(Locale.getDefault()),
                "drawable",
                context.packageName
        )
)

And it works when isMinifyEnabled = true. But this is not an extension from ResourceContainer and my function requires a Context

Можно добавить правило для R8/proguard -keep class packageName.MR$images { *; }
