ButterKnife 5.1.1预防错误

Question

我正在开发一个安卓应用程序，并且在我的应用程序中使用ButterKnife库。现在我需要保护，不幸的是，毛毛刀产生了很多错误。我尝试了很多来自互联网的解决方案，包括ButterKnife Github本身，但都不好。我正在使用ButterKnife 5.1.1，下面是我得到的错误。

我已经将我能找到的所有已知规则添加到'proguard-rules.pro‘文件中，请检查下面的内容。

# Retain generated class which implement Unbinder.
-keep public class * implements butterknife.Unbinder { public <init>(**, android.view.View); }

# Prevent obfuscation of types which use ButterKnife annotations since the simple name
# is used to reflectively look up the generated ViewBinding.
-keep class butterknife.*
-keepclasseswithmembernames class * { @butterknife.* <methods>; }
-keepclasseswithmembernames class * { @butterknife.* <fields>; }

对于黄油刀，使用8.8.1版本。

compile 'com.jakewharton:butterknife:8.8.1'
