Android R8瞬间崩溃

Question

我正在尝试使用 R8 完整模式 构建我的应用程序的发布版本，但它导致崩溃。更具体地说，当通过 Android Studio 安装时，构建将完全正常运行，或者它会立即崩溃并在下面添加堆栈跟踪。

有时它会在配置更改后立即发生，例如 debuggable false 到 debuggable true，有时会在连续构建相同的 gradle 配置后发生，这很奇怪，我无法确定它的行为.

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

Proguard 文件：

-keepclassmembers class fqcn.of.javascript.interface.for.webview {
       public *;
}

## kotlin
-dontwarn org.jetbrains.annotations.**
-keep class kotlin.Metadata { *; }

-dontwarn kotlin.reflect.jvm.internal.**
-keep class kotlin.reflect.jvm.internal.* { *; }

-keepclassmembers class kotlin.Metadata {
   public <methods>;
}

-keepnames @dagger.hilt.android.lifecycle.HiltViewModel class * extends androidx.lifecycle.ViewModel

应用程序是用

构建的

Android Studio 4.2.1
AGP 版本 4.2.1
Gradle版本gradle-6.7.1-all

由于包含 Jetpack Compose，我们还添加了：

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
        kotlinOptions {
            jvmTarget = "1.8"
            freeCompilerArgs += [
                    "-Xallow-jvm-ir-dependencies",
                    "-P",
                    "plugin:androidx.compose.compiler.plugins.kotlin:suppressKotlinVersionCompatibilityCheck=true"
            ]
        }
}


compileOptions {
        coreLibraryDesugaringEnabled true
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
}

coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs:1.1.5'

此外还包括 multiDexEnabled true 和 implementation "org.jetbrains.kotlin:kotlin-reflect:1.5.10" 这可能是一个可能的解决方案。

Answer 1

回答我自己的问题。解决方法是在您的混淆器中添加以下规则-rules.pro:

-keepclassmembers class kotlin.SafePublicationLazyImpl {
    java.lang.Object _value;
}
