签名的应用程序出错！

我的应用使用了外部 Admob jar，但 proguard 正在触摸 jar：

jar 文件位于 /libs/GoogleAdMobAdsSdk-6.2.1.jar

谢谢

LogCat 错误：

Proguard returned with error code 1. See console
Warning: com.google.ads.m: can't find referenced class  
com.google.ads.internal.state.AdState

在 jar 文件中

配置proguard-project.txt：

-libraryjars /libs/GoogleAdMobAdsSdk-6.2.1.jar

-dontpreverify
-repackageclasses ''
-allowaccessmodification
-optimizations !code/simplification/arithmetic
-keepattributes *Annotation*

-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.view.View {
public <init>(android.content.Context);
public <init>(android.content.Context, android.util.AttributeSet);
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 android.os.Parcelable$Creator CREATOR;
}

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

添加后

-keep public class com.google.ads.**

到该文件，eclipse控制台仍然给出以下错误：

Proguard returned with error code 1. See console
Note: there were 160 duplicate class definitions.
Warning: com.google.ads.m: can't find referenced class

感谢您的评论。但这不适用于例如Dropbox Sdkor 其他外部 jars。这些将被 proguard 触摸或更改
听起来您不希望 proguard 更改库文件。您应该为 AdMob SDK jar 添加 -keep public class com.google.ads.**，并为其他 jar 添加类似的内容，这样这些类就不会被重命名。
做了但仍然出现错误，请参阅编辑

标签： android jar admob proguard

【解决方案1】：

我刚刚添加了

-dontwarn com.google.ads.**

到 proguard-project.txt 文件，签名的 apk 工作正常！在这里推荐（就像 Eric 之前说的）：Proguard can't find referenced class com.google.ads.internal.state.AdState

【讨论】：

这真的对我有用..我还按照 Eric Leichtenschlag 11 月 2 日 16:55 的评论添加了。谢谢你们俩..
此代码签署了应用程序，但 admob 广告确实出现并给出了 classnotfoundexception 但@peterdk 代码对我有用。

【解决方案2】：

这对我有用，看来您需要将这两项添加到 proguard 配置中：

-dontwarn com.google.ads.**
-keep class com.google.ads.**  {*;}

【解决方案3】：

-dontwarn com.google.ads.** 这里保护广告类如果您想保护您的班级，请添加 com.pkgname.**
