我更新了一个应用程序，几乎有相同的代码，在以前的版本中，我没有proguard的问题.当我启动应用程序，因为AndroidStudio我没有问题，但当我启动一个签名的应用程序在应用程序的某些部分可以显示此错误：

07-21 14:45:02.156  24372-24372/pe.gob.devida E/AndroidRuntime﹕ FATAL EXCEPTION: main

APIKey已存在且“Google Maps Android API v2”已启用
我认为问题出在proguard-rules.pro

# Add project specific ProGuard rules here.

# directive in build.gradle.

# For more details, see

-dontwarn pe.gob.devida.**
-dontwarn org.simpleframework.**

-keep public class * extends pe.gob.devida.activities.BaseActivity

# and specify the fully qualified class name to the JavaScript interface

使用Gson时，BaseActivity和BaseFragment扩展的类出现错误。

我用这个解决了我的问题：
proguard：

-renamesourcefileattribute SourceFile
-keepattributes  Signature,SourceFile,LineNumberTable
-keep public class * extends android.app.Application

你可以试试这个

-keep class * implements java.io.Serializable {
     static final long serialVersionUID;
     private static final java.io.ObjectStreamField[] serialPersistentFields;
     private void writeObject(java.io.ObjectOutputStream);
     private void readObject(java.io.ObjectInputStream);
     java.lang.Object writeReplace();
     java.lang.Object readResolve();
     private *;
     void set*(***);
     *** get*();
}
# Gson uses generic type information stored in a class file when working with fields. Proguard
# removes such information by default, so configure it to keep all of it.
-keepattributes Signature

# Gson specific classes
-keep class sun.misc.Unsafe { *; }
#-keep class com.google.gson.stream.** { *; }

# Application classes that will be serialized/deserialized over Gson
-keep class com.google.gson.examples.android.model.** { *; }
