Obfuscate android.support.v7.widget.GridLayout問題

Question

我想混淆我的Android應用程序，我使用android.support.v7.appcompat和android.support.v7.GridLayout，但應用程序崩潰與以下 例外：

android.view.InflateException: Binary XML file line #2: Error inflating class android.support.v7.widget.GridLayout

我ProGuard的-project.txt：

-dontusemixedcaseclassnames 
-dontskipnonpubliclibraryclasses 
-verbose 
-dontoptimize 
-dontpreverify 
-keepclasseswithmembernames class * { 
    native <methods>; 
} 

-keepattributes *Annotation*,EnclosingMethod,Signature 

-keep public class * extends android.app.Activity

-keepclassmembers public class * extends android.view.View {

}

} 

-keepclassmembers enum * {

} 

-keep class * implements android.os.Parcelable { 
    public static final android.os.Parcelable$Creator *; 
    public void set*(***); 
    public *** get*(); 
    public *** is*(); 
} 

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

-keep class android.support.v7.widget.** { *; } 
-keep class android.support.v7.internal.** { *; } 
-keep interface android.support.v7.internal.** { *; } 
-keep class android.support.v4.widget.** { *; } 
-keep interface android.support.v4.widget.** { *; } 
-keep class com.viewpagerindicator.** { *; } 

-keep class android.support.v4.app.** { *; } 
-keep class android.support.v4.view.** { *; } 
-keep interface android.support.v4.app.** { *; } 
-keep interface android.support.v4.view.** { *; } 

我怎樣才能解決這個問題呢？

Answer 1

我使用的是類似的東西（也可能是過於寬泛雖然）：

# Preserve all fundamental application classes. 
-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.view.View 
-keep public class * extends android.preference.Preference 
-keep public class * extends android.content.BroadcastReceiver 
-keep public class * extends android.content.ContentProvider 

# Preserve Android support libraries` classes and interfaces 
-keep class android.support.** { *; } 
-keep interface android.support.** { *; } 

Answer 2

#### -- Support Library -- 

# support-v4 
-dontwarn android.support.v4.** 
-keep class android.support.v4.app.** { *; } 
-keep interface android.support.v4.app.** { *; } 
-keep class android.support.v4.** { *; } 

# support-v7 
-dontwarn android.support.v7.** 
-keep class android.support.v7.internal.** { *; } 
-keep interface android.support.v7.internal.** { *; } 
-keep class android.support.v7.** { *; }
