尝试理解proguard（实际上我只是想让它工作），我从一个非常简单的hello world应用程序开始。到现在为止还挺好。然后我添加了我的谷歌云端点。没有其他的。一旦我添加了端点，proguard会抛出异常：
proguard-rules.pro所以我遇到问题的唯一原因是因为云端点I add using android studio。所以我的问题是如何为proguard配置Google Cloud Android应用程序？
由于来自Proguard的失败消息，我将-keepclassmembers class * {
@com.google.api.client.util.Key <fields>;
}
-keepattributes Signature,RuntimeVisibleAnnotations,AnnotationDefault
-keep class com.google.api.** { public *; }
-dontwarn com.google.api.**
-keep class com.google.common.** { public *; }
-dontwarn com.google.common.**
-keep class com.mycompany.cloud.Cloud.** { *; }
-dontwarn com.google.android.gms.**
-dontwarn com.google.common.cache.**
-dontwarn com.google.common.primitives.**
-keep class * extends java.util.ListResourceBundle {
protected Object[][] getContents();
}
-keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable {
public static final *** NULL;
}
-keepnames @com.google.android.gms.common.annotation.KeepName class *
-keepclassmembernames class * {
@com.google.android.gms.common.annotation.KeepName *;
}
从没有任何内容更改为具有以下内容：
