javascript - 如何使用 native react 启用 Proguard？

Question

我想减小我的 APK 大小
我关注了这些 https://facebook.github.io/react-native/docs/signed-apk-android
并运行 ./gradlew bundleRelease 而不是 assembleRelease
但我有错误

Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'. Job failed,

那么我该如何解决它，我是谷歌它，但问题仍然存在!
但是如果没有 Enable Proguard 它工作得很好，我得到了 (Aab & .Apk ) 所以如何解决它!

我认为这个文件有问题，但我不知道如何配置它!

proguard-rules.pro

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}

如果您希望在您的应用程序中使用“react-native-firebase”包时启用 Proguard(在 android/app/build.gradle 中为 minifyEnabled true)，您需要更新您的 proguard 规则。

在 (android/app/proguard-rules.pro)
添加以下行:

-keep class io.invertase.firebase.** { *; }
-dontwarn io.invertase.firebase.**

更多信息可以查看 https://rnfirebase.io/docs/v5.x.x/installation/android就在第 4 步之前。

如果它不起作用，您必须转到您使用的其他软件包的文档，并且必须查找其他首选项以使其设置与启用的 Proguard 兼容。
