发布版本崩溃，而调试版本按预期运行

Question

尝试在设备上运行发布版本时遇到以下异常。

   java.lang.RuntimeException: Unable to get provider com.google.firebase.provider.FirebaseInitProvider: java.lang.IllegalStateException: com.google.android.gms.measurement.AppMeasurement#getInstance has been removed by Proguard. Add keep rule to prevent it.

我正在使用以下proguard配置

-keepclasseswithmembers class * {
    public static com.google.firebase.auth.FirebaseAuth getInstance();
}
-keep public class com.google.firebase.**
-keep public class com.google.firebase.auth.FirebaseAuth

-keep public class com.google.android.gms.measurement.**
-keep public class com.google.firebase.provider.FirebaseInitProvider

您需要在Pro-guard中添加几行：

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

#GooglePlayServices
-keepnames class com.google.android.gms.** {*;}
