發布構建應用程序崩潰導致 proguard 規則

Question

我的應用程序中有一堆 Recycler 視圖，它們從 firestore 數據庫中獲取數據。 在我的調試應用程序中一切正常，但是當我在我的 proguard 中添加minifyEnabled true時，一切正常，但活動主機回收器失敗並出現以下 logcat 錯誤。 我完全不知道如何為 model 類添加保護規則

我剛剛做了我的堆棧跟蹤，這是錯誤

Answer 1

可能是因為proguard而有問題，請確保只是嘗試在您的發布構建類型中禁用縮小

buildTypes {
    release {
        minifyEnabled false
        ------
      }
    }

Answer 2

在您的 proguard 規則中添加以下代碼

-keep class package.to.yourmodels.** { *; }
-keepattributes *Annotation*
-keepattributes Signature
-dontwarn com.squareup.okhttp.*
-dontwarn rx.**
-dontwarn retrofit2.**
-keep class retrofit2.** { *; }
-keepattributes Exceptions
-keepattributes RuntimeVisibleAnnotations
-keepattributes RuntimeInvisibleAnnotations
-keepattributes RuntimeVisibleParameterAnnotations
-keepattributes RuntimeInvisibleParameterAnnotations
