我正在对我的 Android 项目进行首次 Proguard 设置并导出我的 APK 文件，但出现以下错误：（我proguard.cfg在项目根目录中也找不到任何文件）

**项目.属性：**

# 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正确设置proguard。

提前致谢。

终于在本教程的帮助下我得到了答案

我更改了以下内容：

在project.properties: 取消注释或添加这一行：

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

现在我使用了谷歌图书馆，所以我proguard.project.txt会喜欢：

在这里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

在此处添加任何项目特定的保留选项：

-keep class com.google.**
-dontwarn com.google.**

然后，您可以使用以下步骤导出 APK：

  • 右键单击项目
  • 选择导出
  • 按照步骤

如果您有任何疑问，那么您可以随意 ping 我 :)

谢谢你。

在我的情况下使用 Maven，作为依赖项google-api-client带来，导致类似的问题。guava-jdk5

Proguard 上的 Guava wiki 页面建议： https ://code.google.com/p/guava-libraries/wiki/UsingProGuardWithGuava

-dontwarn sun.misc.Unsafe
-dontwarn com.google.common.collect.MinMaxPriorityQueue

在您的 proguard-project.txt 中添加这些行

-keep public class com.google.common.**
-keep public class * extends android.app.Activity
