android - 设置 Proguard 和导出 APK 时出错

Question

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:(我也没有在我的项目根目录中找到任何 proguard.cfg 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准确设置混淆器。

提前致谢。

Answer 1

最后我在这个 Tutorial 的帮助下得到了答案

我更改了以下内容:

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

现在我已经使用了 Google Library，所以我的 proguard.project.txt 会像这样:

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

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您的 APK:

• 右键单击项目
• 选择导出
• 按照步骤操作

如果你有任何疑问，那么你可以随意 ping 我 :)

谢谢。
