如何在发布 apk 中使用 minifyEnable？答案

【问题标题】：How to use minifyEnable in release apk?如何在发布 apk 中使用 minifyEnable？
【发布时间】：2021-08-03 21:58:21
【问题描述】：

我正在尝试使用 Proguard 混淆我的代码，但是当我将 minifyEnable 设置为 true 时，我的发布 apk 崩溃。这是我的 build.gradle：

signingConfig signingConfigs.release
minifyEnabled enableProguardInReleaseBuilds
shrinkResources enableProguardInReleaseBuilds
proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
multiDexKeepFile file('multidex-config.txt')

（enableProguardInReleaseBuilds 为真）

我还尝试在 proguard-rules.pro 中添加一些配置：

-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }
-keep class android.support.v7.app.** { *; }
-keep interface android.support.v7.app.** { *; }

但是没有用。

日志错误：

有人可以帮我吗？提前谢谢！

标签： android react-native proguard

【解决方案1】：

build gradle 应该是这样的

minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile("proguard- 
android.txt"), "proguard-rules.pro"
multiDexKeepFile file('multidex-config.txt')'

在混淆字段名称更改后的代码中，也许您有数据字段或任何不应混淆的类，请尝试找出

非常感谢您的回复。我试过这个，但没有奏效
