的SplashScreenActivity行號38：設置minifyEnabled後爲真，我發現了以下錯誤

firebaseAuth = FirebaseAuth.getInstance();

我ProGuard的規則包括：

-keep class com.google.** {*;}

我試圖尋找無處不在，一無所獲。

我build.gradle：

buildTypes { 
    release { 
     minifyEnabled true 
     shrinkResources true 
     proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     signingConfig signingConfigs.config 
     proguardFile 'C:/Users/vikas/Desktop/phzVendor/phzandvendor/app/proguard-rules.pro' 
    } 
    debug { 
     minifyEnabled true 
     proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     debuggable true 
     signingConfig signingConfigs.config 
     proguardFile 'C:/Users/vikas/Desktop/phzVendor/phzandvendor/app/proguard-rules.pro' 
    } 
}

主要異常是 - java.lang.ClassCastException：com.google.android.gms.internal.zzald無法轉換爲com.google.firebase.auth.UserInfo –

請發佈您的build.gradle文件 –

我知道了，但是當minifyEnabled爲false時，它的工作就是它的工作。我認爲proguard正在混淆某些東西，這導致了這個錯誤。我不知道我必須寫什麼規則才能避免這種情況。 –

磨片設置minifyEnabled爲true這意味着proguard的啓動工程。您需要爲每個庫和應用程序提供適當的proguard配置。

對於火力點，你可以找到CONFIGS here或official docs

而且here is收集許多有用的片段爲ProGuard配置文件中的一個項目。
