我正在我的Android项目和导出我的APK文件上进行第一次proguard设置但我得到以下错误：
（我在项目根目录中也找不到任何proguard.cfg文件）

# To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):
proguard.config=proguard.cfg
# Project target.
target=android-17
android.library.reference.1=..\\librarySlideMenu
android.library.reference.2=../google-play-services_lib
请告诉我解决方案以及如何准确设置proguard。
先谢谢。

最后，在Tutorial
的帮助下，我得到了答案我改变了以下事项：
在 project.properties中： 取消注释或添加此行：
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
现在我使用了Google图书馆，因此 proguard.project.txt 就像：
在此处添加您在项目中使用的库：
-libraryjars /libs/google-api-client-1.10.3-beta.jar
-libraryjars /libs/google-api-client-android2-1.10.3-beta.jar
-libraryjars /libs/google-http-client-1.10.3-beta.jar
-libraryjars /libs/google-http-client-android2-1.10.3-beta.jar
-libraryjars /libs/google-oauth-client-1.10.1-beta.jar
-libraryjars /libs/gson-2.1.jar
-libraryjars /libs/guava-11.0.1.jar
-libraryjars /libs/jackson-core-asl-1.9.4.jar
-libraryjars /libs/jsr305-1.3.9.jar
-libraryjars /libs/protobuf-java-2.2.0.jar
-libraryjars /libs/maps.jar
-keep class com.google.**
-dontwarn com.google.**
然后您可以按照以下步骤导出APK：
如果您有任何查询，那么您可以自由地ping我：）
谢谢。
答案 1 :(得分：3)
在我的案例中使用Maven，google-api-client将guava-jdk5作为依赖项，导致类似的问题。
Proguard上的Guava维基页面建议： https://code.google.com/p/guava-libraries/wiki/UsingProGuardWithGuava
-dontwarn sun.misc.Unsafe
-dontwarn com.google.common.collect.MinMaxPriorityQueue
答案 2 :(得分：2)
在proguard-project.txt
中添加这些行-keep public class com.google.common.**
-keep public class * extends android.app.Activity
