android - react-native android 应用程序在发布 apk 时崩溃

Question

我编写了一个使用 react-native-svg 的混合应用程序在 react-native View 中渲染 svg 图像。一切都很完美。今天，当我为我的应用程序创建发布 apk 并将其部署到模拟器时，它崩溃并出现错误:

只有当我从 proguard-rule.pro 文件中注释 -dontobfuscate 时，我才会看到这个问题。我想混淆我的 apk 代码(我无法控制它。)。我使用的混淆器文件与本例中所示的类似， https://github.com/magicismight/react-native-svg-example/blob/cfb788461efae0de367c97aadcc829cdeb959a8d/android/app/proguard-rules.pro

有没有人遇到过这个问题？关于如何在不启用 proguard-rules 文件中的 -dontobfuscate 的情况下阻止我的应用程序崩溃的任何建议？

编辑 我是 android 开发的新手，我是第一次尝试 proguard。关于如何调试此类问题的任何积极建议都将非常有帮助。

Answer 1

问题与proguard有关。正如现在在自述文件(或 this issue)中所述，您需要将以下行添加到您的 android/app/proguard-rules.pro 文件中:

-keep public class com.horcrux.svg.** {*;}
