Question

我将Google Play服务库添加到了我的应用程序中。一切正常，但我的apk的大小在4（！）倍从350KB增加到1.6MB。要从Google Play服务库中删除未使用的类，我决定使用ProGuard。但是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 lib时我没有出口问题，但我不能用这个库创建apk。我读了很多关于这个问题的内容，但我发现的任何解决方案都没有帮助我。

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
-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

#keep all classes that might be used in XML layouts
-keep public class * extends android.view.View
-keep public class * extends android.app.Fragment
-keep public class * extends android.support.v4.Fragment


#keep all public and protected methods that could be used by java reflection
-keepclassmembernames class * {
  public protected <methods>;
}

-keepclasseswithmembernames class * {
  native <methods>;
}

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

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


-keepclassmembers enum * {
  public static **[] values();
  public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
public static final android.os.Parcelable$Creator *;
}

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

这里是我在导出到apk后获得的错误：

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......

请帮助我！

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Google Play服务库的副本 - 您不应该直接从Android SDK目录引用该库。

https://developers.google.com/android/guides/setup

Answer 3

在生成签名版本时，我一直面临类似的问题和其他一些Prograud。经过大量的搜索，最终我能够解决我的问题。我相信人们有比下面更好的解决方案。

保留最新的SDK和支持的库。
在“/ sdk / tools / progaurd /".
复制.jar文件，例如您的应用程序在“/ sdk / tools / progaurd / libs /”文件夹中需要的“android-support-v13.jar”，“google-play-services.jar”。
在您的应用程序“libs”文件夹中复制.jar。同时删除“android-support-v4.jar”，因为它不是必需的，这里v13已经支持v4
将.jar文件添加到构建路径。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。
在应用程序project.properties文件中添加以下行。请将目标保持为“android-22”。

updateView()

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

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

最诚挚的问候，维克

Answer 4

即使我有谷歌播放服务作为一个库我仍然必须手动添加android-support-v4.jar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文件看起来像这样：

 -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.** { *; }

最后一行使得只有我的代码被混淆了。它更清洁。
