Proguard 使用 Google Play 服务库返回错误

Question

我将 Google Play 服务库添加到我的应用程序中。一切正常，但我的 apk 大小从 350KB 增加到 1.6MB，增加了 4 倍（！）。为了从 Google Play Services 库中删除未使用的类，我决定使用 ProGuard。但现在我无法运行项目或将其导出到 apk，因为 ProGuard 返回错误。当我不使用 GPS 库时，导出没有问题，但我无法使用该库创建 apk。 我阅读了很多关于这个问题的信息，但我找到的任何解决方案都对我没有帮助。

这是我的 proguard-project.txt（推荐 here）

-keep class * extends java.util.ListResourceBundle {
    protected Object[][] getContents();
}

-keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable {
    public static final *** NULL;
}

-keepnames @com.google.android.gms.common.annotation.KeepName class *
-keepclassmembernames class * {
    @com.google.android.gms.common.annotation.KeepName *;
}

-keepnames class * implements android.os.Parcelable {
    public static final ** CREATOR;
}

这是我的 proguard.cng

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify

}

}

-keepclasseswithmembernames class * {

}


-keepclassmembers enum * {

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

-keep class * implements android.os.Parcelable {

}

-dontwarn **CompatHoneycomb
-dontwarn org.htmlcleaner.*
-dontwarn com.google.android.gms.**
-keep class com.google.android.gms.common.GooglePlayServicesUtil {*;}
-keep class com.google.ads.** { *;}

这里是我导出到 apk 后得到的一个错误：

我的本​​地配置可能有问题... 我尝试了 -keep 和 -dontwarn 不同的课程，但现在没有任何帮助......

请帮帮我！

Answer 1

将 android-support-v4.jar 添加到您的项目中

Answer 2

如果您使用 Eclipse ADT：您应该引用您复制到开发工作区的库 Google Play Services 的副本 - 您不应该直接从 Android SDK 目录引用该库。

Answer 3

在生成签名版本时，我遇到了类似的问题，而 Prograud 几乎没有其他问题。经过大量搜索，我终于能够解决我的问题。我相信人们有比下面一个更好的解决方案。

1. 保留最新的 SDK 和支持的库。
2. 在“/sdk/tools/progaurd/”中创建一个文件夹“libs”。
3. 将应用程序所需的 .jar 文件（例如“android-support-v13.jar”、“google-play-services.jar”）复制到“/sdk/tools/progaurd/libs/”文件夹中。李>
4. 将 .jar 复制到您的应用程序“libs”文件夹中。 同时删除“android-support-v4.jar”，因为它不是必需的，这里 v13 已经支持 v4
5. 将 .jar 文件添加到您的构建路径。 同时从构建路径中删除“android-support-v4.jar”，因为它不是必需的，这里 v13 已经支持 v4。
6. 在您的应用程序 project.properties 文件中添加以下行。请仅将目标保留为“android-22”。

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt
# Project target.
target=android-22
android.library.reference.1=../../dev/sdk/extras/google/google_play_services/libproject/google-play-services_lib

1. 我的 Progaurd 文件“proguard-android.txt”。请根据您的要求进行更改。

Answer 4

即使我有 google play 服务作为库，我仍然必须手动将 android-support-v4.jar 添加到我的 libs 文件夹并右键单击并添加到 Eclipse 中的构建路径。

我的 proguard 文件如下所示：

 -optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontwarn com.google.**
-dontpreverify
-dontwarn android.support.v4.**
-dontwarn org.apache.commons.codec.binary.Base64
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*





-keep class !mycode.** { *; }

最后一行使它只有我的代码被混淆了。它更清洁。
