Question

最近我用uk.co.chrisjenx.calligraphy库在我的观点上设置字体。在调试模式下，一切正常，但在发布模式下，通过单击任何活动，它具有InflateException。我需要一些帮助来处理它。。这是我的ProGuard规则：

    -keep class butterknife.** { *; }
-dontwarn butterknife.internal.**
-keep class **$$ViewBinder { *; }

-keepclasseswithmembernames class * {
    @butterknife.* <fields>;
}

-keepclasseswithmembernames class * {
    @butterknife.* <methods>;
}

-dontwarn com.squareup.okhttp.**
-keep class android.**
-dontwarn android.**
-dontwarn com.google.android.gms.**

，这是Android Studio日志：

Answer 1

尝试将此规则添加到Proguard规则文件中：

-keepclassmembernames class android.support.v7.widget.** { *; }

我不确定它是否是最佳解决方案，但它为我做了诀窍。

InflateException只是在发布模式下
