Question

我正在使用proguard来混淆代码。我在控制台

中收到以下错误

Proguard returned with error code 1. See console

我的 project.properties 文件在这里

# This file is automatically generated by Android Tools.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file must be checked in Version Control Systems.
#
# To customize properties used by the Ant build system edit
# "ant.properties", and override values to adapt the script to your

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

# Project target.
target=android-10

我的 proguard-project.txt 就在这里

# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}

如何解决这个问题？

Answer 1

我通过在 proguard-project.txt

中添加它来修复它

-keep public class * extends com.phonegap.api.Plugin 
-keep public class org.apache.cordova.DroidGap 
-keep public class org.apache.cordova.** 
-libraryjars /Users/Nasir/Desktop/libs/commons-codec.jar
-dontwarn android.webkit.*

Answer 2

您可以将以下内容添加到proguard-project.txt中。它在Cordova（PhoneGap）2.1上为我工作：

-keep public class * extends com.phonegap.api.Plugin 
-keep public class * extends org.apache.cordova.api.Plugin 
-keep public class org.apache.cordova.DroidGap 
-keep public class org.apache.cordova.** 
-libraryjars libs/commons-codec-1.7.jar
-dontwarn android.webkit.*
-dontwarn org.apache.**

如果proguard为ON，则在生成.apk文件时出错
