问题描述

开启混淆后，调用getBinding去反射时会崩溃

期望结果

如何复现

调用getBinding时报错

when (itemViewType) {
    R.layout.item_album -> {
        getBinding<ItemAlbumBinding>().apply {
            ...
        }
    }

   ...
}

希望快速解决请Fork仓库复现问题并附上链接, 否则只能等有空才能排查 凭空猜测只会让问题晦涩难懂, 浪费本项目可持续维护时间

-keep class implements androidx.viewbinding.ViewBinding {;}

在混淆规则中保留了ViewBinding后解决了

[liangjingkanji]

开启混淆, 你运行sample项目打开ViewBindingFragment界面会崩溃吗?

[aikorola]

@liangjingkanji 没试过运行项目

[liangjingkanji]

那麻烦你运行下吧, 我看混淆好像并不影响调用bind()

sample写的这么好你们都不带运行的, 不会看都没看过吧

ViewBinding封装使用反射是必须的, 并且存在缓存, 不会影响列表性能

[liangjingkanji]

无法复现问题, 此问题关闭

[liangjingkanji]

疑似AGP8开启的android.enableR8.fullMode模式导致, 但我无法复现
