使用ANT 1.8.2和proguarg 4.8.1构建项目时

 [proguard] Unexpected error while evaluating instruction:
 [proguard]   Class       = [android/support/v4/view/AccessibilityDelegateCompat$AccessibilityDelegateJellyBeanImpl]
 [proguard]   Method      = [newAccessiblityDelegateBridge(Landroid/support/v4/view/AccessibilityDelegateCompat;)Ljava/lang/Object;]
 [proguard]   Instruction = [18] areturn
 [proguard]   Exception   = [java.lang.IllegalArgumentException] (Can't find any super classes of [android/support/v4/view/AccessibilityDelegateCompatIcs$1] (not even immediate super class [android/view/View$AccessibilityDelegate]))
 [proguard] Unexpected error while performing partial evaluation:
 [proguard]   Class       = [android/support/v4/view/AccessibilityDelegateCompat$AccessibilityDelegateJellyBeanImpl]
 [proguard]   Method      = [newAccessiblityDelegateBridge(Landroid/support/v4/view/AccessibilityDelegateCompat;)Ljava/lang/Object;]
 [proguard]   Exception   = [java.lang.IllegalArgumentException] (Can't find any super classes of [android/support/v4/view/AccessibilityDelegateCompatIcs$1] (not even immediate super class [android/view/View$AccessibilityDelegate]))

BUILD FAILED
E:\adt-bundle-windows\sdk\tools\ant\build.xml:864: java.lang.IllegalArgumentException:     Can't find any super classes of [android/support/v4/view/AccessibilityDelegateCompatIcs$1] (not even immediate super class [android/view/View$AccessibilityDelegate])

android-support-v4.jar在课程路径和项目依赖中... 从Eclipse开始，所有but debug版本都已正常建立。 Ant显示那些错误...

如何避免这种情况？我理解如果Eclipse构建好了，Ant也必须构建......

P.S。我的项目是android-10目标，如果有人建议，我不想让它成为目标-16。

尝试将这些添加到proguard.cf中怎么样？

-libraryjars   libs/android-support-v4.jar
-dontwarn android.support.v4.**    
-keep class android.support.v4.** { *; }  
-keep interface android.support.v4.app.** { *; }  
-keep public class * extends android.support.v4.**  
-keep public class * extends android.app.Fragment

您应该在project.properties中指定目标SDK，在这种情况下包含'android.view.View $ AccessibilityDelegate'（SDK级别14或更高级别）。 ProGuard的缩小/优化/混淆至少需要用于编译应用程序和其库的基本SDK。支持库是针对这个更新的SDK编译的，因此ProGuard也需要它。

您仍然可以在AndroidManifest.xml中指定不同的目标/最小/最大SDK，以便运行该应用程序。您当然应该确保应用程序确实与那些指定的SDK兼容。

Ant + Proguard提供android-support-v4.jar错误
