读取 json 文件时出错。问题是什么？

Question

在 Android Studio 中，我生成了一个 APK 文件以发布到 Google Play。但是当我从 APK 文件检查我的游戏如何运行时，当我转到菜单时，游戏崩溃了。读取 json 文件时出现错误。同时，当我通过 USB 从 Android Studio 将游戏安装到智能手机时，读取 json 文件没有错误 - 游戏运行正常。有什么问题？

检查 build.gradle 中的 minifyEnabled（模块：...）。它应该是 false 或创建 proguard 规则

buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
