Question

I have just become aware of obfuscation and want to setup proguard to work with my application. I am working in eclipse and I set it up my project.properties as suggested many places, as such

# 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

and my proguard-project.txt as

# 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

}

}

-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 *;
#}

When I exported it worked fine the first time however I noticed a mistake when I ran the application so I fixed the mistake and since then every time I try to export the application I get the following error.

[2016-06-10 17:55:33 - route_planner_TT] Proguard returned with error code 1. See console

Answer 1

好像你应该使用SDK Manager下载/重新下载Android SDK 9。

Answer 2

在proguard-project.txt中，使用以下选项包含android.jar：

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

但您似乎在Windows计算机上工作。您需要将其更改为指向计算机上安装的android.jar的正确Windows路径。
