启用 Proguard 后无法实例化 Fragment

分类：编程问答

如何解决启用 Proguard 后无法实例化 Fragment

我在启用 minified 和 proguard 后遇到运行时异常。它只发生在我使用深层链接导航到的动态特征模块中的片段上。 :app 模块中的另一个片段不会受到深层链接或使用默认底部视图导航的影响。这是日志猫：

我尝试添加从 here 获得的这一行，但不起作用。

-keepnames class androidx.navigation.fragment.NavHostFragment

有人经历过吗？我该怎么办？

更新：

shared_depencies.gradle 跨模块实现：

dependencies {
    implementation "androidx.appcompat:appcompat:$appcompat_version"
    implementation "androidx.core:core-ktx:$core_ktx_version"
    implementation "androidx.constraintlayout:constraintlayout:$constraint_version"
    implementation "androidx.navigation:navigation-fragment-ktx:$navigation_version"
    implementation "androidx.navigation:navigation-ui-ktx:$navigation_version"

    testImplementation "junit:junit:$junit_version"
    androidTestImplementation "androidx.test.ext:junit:$androidx_junit_version"
    androidTestImplementation "androidx.test.espresso:espresso-core:$espresso_version"

    implementation "androidx.multidex:multidex:$multidex_version"
    debugImplementation "com.squareup.leakcanary:leakcanary-android:$leakcanary_version"

    // UI
    implementation "androidx.recyclerview:recyclerview:$recyclerview_version"
    implementation "com.google.android.material:material:$material_version"
    implementation "io.coil-kt:coil:$coil_version"
    implementation "com.airbnb.android:lottie:$lottie_version"
    implementation "com.facebook.shimmer:shimmer:$shimmer_version"

    // Hilt
    implementation "com.google.dagger:hilt-android:$hilt_version"
    kapt "com.google.dagger:hilt-compiler:$hilt_version"
    implementation "androidx.hilt:hilt-lifecycle-viewmodel:$hilt_jetpack_version"
}

共享依赖被应用：

apply from: '../shared_dependencies.gradle'

核心模块依赖：

dependencies {
    //noinspection DifferentStdlibGradLeversion
    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"

    // Room
    api "androidx.room:room-runtime:$room_version"
    kapt "androidx.room:room-compiler:$room_version"
    androidTestImplementation "androidx.room:room-testing:$room_version"

    // Retrofit
    api "com.squareup.retrofit2:retrofit:$retrofit_version"
    api "com.squareup.retrofit2:converter-gson:$retrofit_version"
    api "com.squareup.okhttp3:logging-interceptor:$logging_interceptor_version"

    // Coroutine
    implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:$kotlin_coroutines_version"
    implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:$kotlin_coroutines_version"
    implementation "androidx.room:room-ktx:$room_version"

    // Lifecycle
    api "androidx.lifecycle:lifecycle-livedata-ktx:$lifecycle_version"
    api "androidx.activity:activity-ktx:$activity_ktx_version"
    api "androidx.fragment:fragment-ktx:$fragment_ktx_version"

    // Security
    implementation "net.zetetic:android-database-sqlcipher:$sqlcipher_version"
    implementation "androidx.sqlite:sqlite-ktx:$sqlite_version"
}

应用模块依赖

dependencies {
    implementation project(":core")
    //noinspection DifferentStdlibGradLeversion
    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
}

动态特性模块依赖：

dependencies {
    implementation project(":app")
    implementation project(":core")
    //noinspection DifferentStdlibGradLeversion
    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
}

附加信息：

  • 如果 :app 模块也被混淆，就会发生这种情况
  • 如果只有 :core 模块被混淆了，没关系
  • 动态功能模块根本没有被混淆

解决方法

结果我必须更改我在动态功能模块片段中传递给 Dagger 的上下文。因此，在我的情况下，使用 requireContext() 代替 requireActivity().appicationContext。代码应该是这样的：

DaggerFavoriteComponent.builder()
    .context(requireActivity())
    .appDependencies(
        EntryPointAccessors.fromApplication(
            requireActivity().applicationContext,FavoriteModuleDependencies::class.java
        )
    )
    .build()
    .inject(this)
