Obfuscate android.support.v7.widget.GridLayout question

Question

Je suis en train d'obscurcir mon application android, où j'utilise android.support.v7.appcompat et android.support.v7.GridLayout, mais l'application plante avec le suivant exception:

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

Comment puis-je résoudre ce problème?

Answer 1

J'utilise quelque chose comme ça (il peut être trop large si).

# 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.** { *; }
