从Eclipse导出我的Android应用程序时出现错误，该应用程序将android-support-v4.jar与Proguard一起使用

Question

有人可以帮我在Android应用程序中使用ProGuard的问题吗？

这是我的控制台向我显示的内容。

我认为在罐子里可能有些不适。 如何使用下面的Proguard.cfg文件指定其他库jar

  optimizationpasses 5

 -dontpreverify
 -verbose

  -libraryjars 'E:\Himanshu\AndroidViewPager\libs\android-support-v4.jar'
  -dontskipnonpubliclibraryclasses
  -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>;
}

 -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 *;
  }

Answer 1

在proguard.cfg中添加以下内容对我有用。 我认为是因为您没有使用蜂窝，但是兼容性库中包含一些蜂窝特定的内容。

-dontwarn CompatHoneycomb -keep class android.support.v4. { *; }
-dontwarn **CompatCreatorHoneycombMR2
-dontwarn **ActivityCompatHoneycomb
-dontwarn **MenuCompatHoneycomb

另外，移除

libraryjars 'E:\Himanshu\AndroidViewPager\libs\android-support-v4.jar'

Answer 2

我遇到过同样的问题。 原来，我需要更新项目的构建目标。

看起来android-support-v4.jar的版本需要与项目构建目标版本匹配才能使proguard正常工作。 就我而言， android-support-v4.jar revision 10需要在Package Explorer Project> Properties> Android中设置构建目标Android 4.1.2 (API 16) 。

在AndroidManifest.xml ，我仍然设置了android:targetSdkVersion="13" 。 此设置似乎与问题无关。

方法void setShowAsAction(int)在兼容性库中不可用。 尝试使用菜单的xml文件参数

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@[+][package:]id/resource_name"
      android:title="string"
      android:titleCondensed="string"
      android:icon="@[package:]drawable/drawable_resource_name"
      android:onClick="method name"
      android:showAsAction=["ifRoom" | "never" | "withText" | "always" |
                            "collapseActionView"]
      .../>
</menu>
