如果proguard爲ON，則生成.apk文件時出錯

Question

我正在使用proguard來混淆代碼。 我收到以下錯誤控制檯

Proguard returned with error code 1. See console

我project.properties文件是在這裏

# 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 
# project structure. 
# 
# 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proguard的-project.txt在這裏

# 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 *; 
#} 

如何解決這個問題？

Answer 1

我固定它在我的proguard的-project.txt添加此

-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

您可以添加以下到您的ProGuard-project.txt。它爲我工作在科爾多瓦（PhoneGap）2.1：

-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.**
