Android Proguard ExceptionInInitializerError和RuntimeException

Question

我想混淆我的.apk,我和Proguard有些麻烦.使用eclipse我启用了这个:

# To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

我正在使用4个外部库:

• Android的支持,v4.jar
• 九老的Android lib.jar
• GSON-2.2.2.jar
• 公地IO-2.4.jar

我想我在使用gson时遇到了麻烦:

private static Type MY_DATA_TYPE = new TypeToken<Pair<Map<Point, Void>, Integer>>() {}.getType();

我每次使用它:

FATAL EXCEPTION: main
java.lang.ExceptionInInitializerError at com.myapp.MyActivity.onCreate(Unknown Source)

...

Caused by: java.lang.RuntimeException: Missing type parameter.
at com.google.gson.reflect.TypeToken.getSuperclassTypeParameter(Unknown Source)
at com.google.gson.reflect.TypeToken.<init>(Unknown Source)

我正在使用这个选项,但我想它不会有帮助:

-keepattributes Exceptions, InnerClasses, *Annotation*, EnclosingMethod

-dontskipnonpubliclibraryclassmembers
-libraryjars .../libs/android-support-v4.jar
-libraryjars .../libs/nine-old-android-lib.jar
-libraryjars .../libs/gson-2.2.2.jar
-libraryjars .../libs/commons-io-2.4.jar


-keep class java.** { *; }
-keep class android.** { *; }
-keep class org.** { *; }
-keep class com.google.** { *; }
-keep class com.facebook.** { *; }
-keep class com.nineoldandroids.** { *; }

我该如何解决这个问题并创建一个可以正常工作的混淆的.apk？
谢谢你的时间.

Answer 1

猜猜这是一个gson"问题",这是解决方案:

-keepattributes Signature
-keep class sun.misc.Unsafe { *; }
-keep class com.google.gson.examples.android.model.** { *; }
