本文介绍了一种在使用ProGuard进行Android应用签名时遇到的错误及其解决方案。主要问题是由于ProGuard无法找到引用的类，通过在配置文件中添加特定的忽略警告指令解决了此问题。

今天在为app签名发布的时候，在最后生成apk文件的时候出现了错误：

Proguard returned with error code 1. See console

控制台输出信息如下：

我的proguard.cfg文件内容如下：

-optimizationpasses 5

-dontusemixedcaseclassnames

-dontskipnonpubliclibraryclasses

-dontpreverify

-verbose

-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-keep public class * extends android.app.Activity

-keep public class * extends android.app.Application

-keep public class * extends android.app.Service

-keep public class * extends android.content.BroadcastReceiver

-keep public class * extends android.content.ContentProvider

-keep public class * extends android.app.backup.BackupAgentHelper

-keep public class * extends android.preference.Preference

-keep public class com.android.vending.licensing.ILicensingService

-keepclasseswithmembernames class * {

native <methods>;

}

-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.app.Activity {

public void *(android.view.View);

}

-keepclassmembers enum * {

public static **[] values();

public static ** valueOf(java.lang.String);

}

-keep class * implements android.os.Parcelable {

public static final android.os.Parcelable$Creator *;

}

临时解决方法：直接把

proguard.config=proguard.cfg

这个配置给删除掉，就可以成功签名生成apk了

很明显不是网上所说的路径或者空格的问题，是使用proguard时有关外来jar包所带来的问题，找不到相应的class文件

所以解决方法：根据提示，在proguard.cfg文件中添加：

-dontwarn twitter4j.internal.logging.**

-dontwarn oauth.signpost.signature.**

解决！
