无法使用ProGuard实例化AndroidPlatform类 [英] Failed to instantiate AndroidPlatform class using ProGuard

问题描述

根据Android minifyEnabled和shrinkResources时，预计Android应用程序构建的 release 版本将成功运行. com/studio/build/shrink-code?utm_source = android-studio#shrink-resources"rel =" nofollow noreferrer>文档，Crashlytics和Proguard.

It is expected for the release version of the Android app's build to run successfully when enabling minifyEnabled and shrinkResources per the Android documentation, Crashlytics, and Proguard.

此问题的代码可在开源GitHub存储库中找到倒数.

The code for this issue may be found in the open-sourced GitHub repository for Coinverse.

• 从Google Play下载后，该应用程序的 release 版本立即崩溃.

在没有minifyEnabled和shrinkResources的情况下，应用程序可以按预期的生产方式运行，并且应用程序的大小从〜4mb到〜10mb.

Without minifyEnabled and shrinkResources the app runs as expected in production, and the app size goes from ~4mb to ~10mb.

错误日志表明这是Firebase兼容性问题，因此建议您在StackOverflow上发表这篇文章. - Android上的Firebase我需要什么ProGuard配置?

The error log suggests it is an issue with Firebase compatibility and recommends this StackOverflow post. - What ProGuard configuration do I need for Firebase on Android?

ProGuard存在类似问题- transformClassesAndResourcesWithProguardForRelease失败.

There is a similar issue with ProGuard - transformClassesAndResourcesWithProguardForRelease FAILED.

摘要

启用了Crashlytics.

With Crashlytics enabled.

Crashlytics Core: Failed to execute task

未启用Crashlytics.

App.kt

尝试初始化 FirebaseHelper.kt 类时，应用的发行版崩溃.

The release version of the app is crashing when attempting to initialize the FirebaseHelper.kt class.

class App : Application() {
    val component = DaggerComponent.builder()
            .utilsModule(UtilsModule(this))
            .build()

    override fun onCreate() {
        super.onCreate()
        // Here is where the crash occurs.
        component.firebaseHelper()
        MoPub.initializeSdk(this, SdkConfiguration.Builder(AD_UNIT_ID).build(), initSdkListener())
    }

    private fun initSdkListener() = SdkInitializationListener { /* MoPub SDK initialized.*/ }
}

FirebaseHelper.kt

@Singleton
class FirebaseHelper @Inject constructor(context: Context) {
    private val LOG_TAG = FirebaseHelper::class.java.simpleName

    init {
        if (BuildConfig.BUILD_TYPE == open.name) {
            var openSharedStatus = false
            FirebaseApp.getApps(context).map { app ->
                if (app.name.equals(open.name))
                    openSharedStatus = true
            }
            if (!openSharedStatus)
                FirebaseApp.initializeApp(
                        context,
                        FirebaseOptions.Builder()
                                .setApplicationId(APP_ID_OPEN_SHARED)
                                .setApiKey(APP_API_KEY_OPEN_SHARED)

        } catch (exception: FirebaseRemoteConfigException) {
            Crashlytics.log(Log.ERROR, LOG_TAG, "initializeRemoteConfig: ${exception.localizedMessage}")
        }
    }
}

尝试解决方案

1.删除Crashlytics.

A.删除所有Crashlytics.log(...)

B.在 build.gradle(:app)

// apply plugin: 'io.fabric'

...
// implementation 'com.crashlytics.sdk.android:crashlytics:2.10.1'

C.从 build.gradle(android)

 repositories {
    ...
    // maven { url 'https://maven.fabric.io/public' }
 }
 dependencies {
     ...
     // classpath 'io.fabric.tools:gradle:1.28.0'
 }

2.使用Proguard处理模型到Firestore数据库的序列化/反序列化.

A. 添加 proguard.cfg 规则

# Add this global rule
-keepattributes Signature

-keepclassmembers class app.coinverse.analytics.models.** {
  *;
}
-keepclassmembers class app.coinverse.analytics.models.ContentAction.** {
  *;
}
-keepclassmembers class app.coinverse.analytics.models.UserAction.** {
  *;
}
-keepclassmembers class app.coinverse.analytics.models.UserActionCount.** {
  *;
}
-keepclassmembers class app.coinverse.feed.models.** {
  *;
}
-keepclassmembers class app.coinverse.feed.models.FeedViewState.** {
 *;
}
-keepclassmembers class app.coinverse.feed.models.FeedViewState.Content.** {
 *;
}
-keepclassmembers class app.coinverse.feed.models.FeedViewState.ContentToPlay.** {
 *;
}
-keepclassmembers class app.coinverse.feed.models.FeedViewState.ContentPlayer.** {
 *;
}
-keepclassmembers class app.coinverse.priceGraph.models.** {
  *;
}
-keepclassmembers class app.coinverse.priceGraph.models.ExchangeOrderData.** {
  *;
}
-keepclassmembers class app.coinverse.priceGraph.models.ExchangeOrdersDataPoints.** {
  *;
}
-keepclassmembers class app.coinverse.priceGraph.models.MaximumPercentPriceDifference.** {
  *;
}
-keepclassmembers class app.coinverse.priceGraph.models.Order.** {
  *;
}
-keepclassmembers class app.coinverse.priceGraph.models.PercentDifference.** {
  *;
}
-keepclassmembers class app.coinverse.priceGraph.models.PriceGraphData.** {
  *;
}
-keepclassmembers class app.coinverse.priceGraph.models.PriceGraphXAndYConstraints.** {
  *;
}
-keepclassmembers class app.coinverse.priceGraph.models.PricePair.** {
  *;
}
-keepclassmembers class app.coinverse.user.models.** {
  *;
}
-keepclassmembers class app.coinverse.user.models.User.** {
  *;
}
-keepclassmembers class app.coinverse.utils.** {
  *;
}
# If Enums are used in the database, use 'ADB Clear App Data and Restart', and then re-run.
-keepclassmembers enum * { *; }

B.定义模型的无参数构造函数.对于已经具有data class构造函数中定义的默认值的模型，这不是必需的.但是，如果没有显式定义无参数的构造函数，即为错误 .

B. Define models' no-argument constructors. This should not be required for models that already have default values defined in the data class constructor. However, there is an error without explicitly defining the no-argument constructor, "users does not define no argument constructor".

C.通过在上方添加Proguard规则来注释枚举，以保留枚举的成员.这些实现只需一种.

C. Handle Enums by annotating enum names with @SerializedName and adding the Proguard rule above to keep enumerations' members. Only one of these implementations should be required.

3. 为Firebase添加 proguard.cfg 规则.

-keep class com.firebase.** { *; }
-keep class org.apache.** { *; }
-keepnames class com.fasterxml.jackson.** { *; }
-keepnames class javax.servlet.** { *; }
-keepnames class org.ietf.jgss.** { *; }
-dontwarn org.w3c.dom.**
-dontwarn org.joda.time.**
-dontwarn org.shaded.apache.**
-dontwarn org.ietf.jgss.**

# Only necessary if you downloaded the SDK jar directly instead of from maven.
-keep class com.shaded.fasterxml.jackson.** { *; }

4. 添加pro-guard-rules-release.txt

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules-release.txt'
testProguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules-test.txt'

推荐答案

我遇到了类似的问题，并且从Fabric完全迁移到Firebase Crashlytics为我解决了该问题:

I've had a similar issue and fully migrating from Fabric to Firebase Crashlytics fixed the issue for me: https://firebase.google.com/docs/crashlytics/get-started-new-sdk?platform=android&authuser=0
