开启R8混淆后应用崩溃，报SecurityException权限异常求助

我们在Gradle配置中启用了R8，当将minifyEnabled设置为true时应用崩溃，抛出如下异常：

Gradle.properties配置 #

android.enableR8 = true
android.enableR8.fullMode=true
useProguard = true

build.gradle配置 #

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

解决方案 #

1. 添加ProGuard规则保留OPPO内部Telephony相关类 #

在proguard-rules.pro文件中添加以下规则，避免R8混淆或移除OPPO系统内部的telephony相关类：

-keep class com.oplus.internal.telephony.** { *; }
-dontwarn com.oplus.internal.telephony.**

2. 移除Gradle配置中的冲突项 #

当前配置同时启用了R8和ProGuard，两者存在冲突，建议删除useProguard = true配置，修改后的Gradle.properties如下：

android.enableR8 = true
android.enableR8.fullMode=true
# useProguard = true 已注释或删除

原因说明 #

com.oplus.internal.telephony是OPPO系统专属的内部包，应用调用相关接口时，R8的full优化模式可能会误处理该包的引用，导致系统校验包UID时出现不匹配的情况。添加保留规则可确保相关类不被混淆或移除，同时清理冲突的配置项能避免混淆工具的行为异常。
