为Android应用程序设置proguard项目

Question

我刚刚意识到混淆，并希望设置proguard与我的应用程序一起工作。我在日食工作，我把它我project.properties所建议的很多地方，因为这样

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

# Project target. 
target=android-23 
android.library.reference.1=../../Resources/route_planner_app_basic 

和我ProGuard的-project.txt作为

# 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:

-injars  libs 
-outjars  bin/classes-processed.jar 
-libraryjars /usr/local/java/android-sdk/platforms/android-9/android.jar

    public <init>(android.content.Context, android.util.AttributeSet, int); 
    public void set*(...); 
} 

-keepclasseswithmembers class * { 
    public <init>(android.content.Context, android.util.AttributeSet); 
} 

-keepclasseswithmembers class * { 
    public <init>(android.content.Context, android.util.AttributeSet, int); 
} 

-keepclassmembers class * extends android.content.Context { 
    public void *(android.view.View); 
    public void *(android.view.MenuItem); 
} 

-keepclassmembers class * implements android.os.Parcelable { 
    static ** CREATOR; 
} 

-keepclassmembers class **.R$* { 
    public static <fields>; 
} 

-keepclassmembers class * { 
    @android.webkit.JavascriptInterface <methods>; 
} 

# 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 *; 
#} 

当我出口它的工作罚款但是当我第一次运行应用程序时，我发现有一个错误，所以我修复了这个错误，从那时起，每次我尝试导出应用程序时，都会收到以下错误消息。

这是五个小时前，我一直拉着我的头发，因为请帮助。

Answer 1

在你的ProGuard-project.txt您包括使用下列选项的android.jar：

-libraryjars /usr/local/java/android-sdk/platforms/android-9/android.jar 

，但你似乎在Windows计算机上运行。您需要将其更改为指向安装在计算机上的android.jar的正确Windows路径。

Answer 2

好像只是应该使用SDK Manager下载/重新下载Android SDK 9。
