ProGuard, version 5.2.1
Note: the configuration specifies that none of the methods of class 'android.util.Log' have any side effects

Note: com.google.android.gms.internal.zzast: can't find dynamically referenced class android.os.SystemProperties
Note: com.squareup.picasso.Utils: can't find dynamically referenced class com.squareup.okhttp.OkHttpClient
Note: com.google.android.gms.dynamite.DynamiteModule accesses a declared field 'MODULE_ID' dynamically
Maybe this is program field 'com.google.android.gms.dynamite.descriptors.com.google.android.gms.flags.ModuleDescriptor { java.lang.String MODULE_ID; }'
Note: com.google.android.gms.dynamite.DynamiteModule accesses a declared field 'MODULE_VERSION' dynamically
Maybe this is program field 'com.google.android.gms.dynamite.descriptors.com.google.android.gms.flags.ModuleDescriptor { int MODULE_VERSION; }'
Note: com.google.android.gms.dynamite.DynamiteModule accesses a declared field 'sClassLoader' dynamically
Maybe this is program field 'com.google.android.gms.dynamite.DynamiteModule$DynamiteLoaderClassLoader { java.lang.ClassLoader sClassLoader; }'
Note: the configuration keeps the entry point 'com.google.android.gms.ads.identifier.AdvertisingIdClient { com.google.android.gms.internal.zzcn zza(android.content.Context,com.google.android.gms.common.zza); }', but not the descriptor class 'com.google.android.gms.common.zza'
Note: the configuration keeps the entry point 'com.google.android.gms.flags.impl.FlagProviderImpl { void init(com.google.android.gms.dynamic.zzd); }', but not the descriptor class 'com.google.android.gms.dynamic.zzd'
Note: the configuration keeps the entry point 'com.google.android.gms.measurement.AppMeasurement { void registerOnScreenChangeCallback(com.google.android.gms.measurement.AppMeasurement$zzd); }', but not the descriptor class 'com.google.android.gms.measurement.AppMeasurement$zzd'
Note: the configuration keeps the entry point 'com.google.android.gms.measurement.AppMeasurement { void unregisterOnScreenChangeCallback(com.google.android.gms.measurement.AppMeasurement$zzd); }', but not the descriptor class 'com.google.android.gms.measurement.AppMeasurement$zzd'
Note: the configuration keeps the entry point 'com.google.firebase.iid.FirebaseInstanceId { com.google.firebase.iid.FirebaseInstanceId getInstance(com.google.firebase.FirebaseApp); }', but not the descriptor class 'com.google.firebase.FirebaseApp'
Note: the configuration keeps the entry point 'com.sothree.slidinguppanel.SlidingUpPanelLayout { void setScrollableViewHelper(com.sothree.slidinguppanel.ScrollableViewHelper); }', but not the descriptor class 'com.sothree.slidinguppanel.ScrollableViewHelper'
Note: the configuration keeps the entry point 'com.sothree.slidinguppanel.SlidingUpPanelLayout { void setPanelState(com.sothree.slidinguppanel.SlidingUpPanelLayout$PanelState); }', but not the descriptor class 'com.sothree.slidinguppanel.SlidingUpPanelLayout$PanelState'
Note: the configuration keeps the entry point 'com.sothree.slidinguppanel.SlidingUpPanelLayout { void setPanelStateInternal(com.sothree.slidinguppanel.SlidingUpPanelLayout$PanelState); }', but not the descriptor class 'com.sothree.slidinguppanel.SlidingUpPanelLayout$PanelState'
Note: there were 2 references to unknown classes.
You should check your configuration for typos.
(http://proguard.sourceforge.net/manual/troubleshooting.html#unknownclass)
Note: there were 3 classes trying to access generic signatures using reflection.
You should consider keeping the signature attributes
(using '-keepattributes Signature').
(http://proguard.sourceforge.net/manual/troubleshooting.html#attributes)
Note: there were 8 unkept descriptor classes in kept class members.
You should consider explicitly keeping the mentioned classes
(using '-keep').
(http://proguard.sourceforge.net/manual/troubleshooting.html#descriptorclass)
Note: there were 2 unresolved dynamic references to classes or interfaces.
You should check if you need to specify additional program jars.
(http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclass)
Note: there were 3 accesses to class members by means of introspection.
You should consider explicitly keeping the mentioned class members
(using '-keep' or '-keepclassmembers').
(http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclassmember)
Warning:there were 318 unresolved references to classes or interfaces.
You may need to add missing library jars or update their versions.
If your code works fine without the missing classes, you can suppress
the warnings with '-dontwarn' options.

我添加了此代码以从 app-release apk 中删除日志并收到类似 IOException 的错误，在此请先更正上述警告。我不知道如何纠正这个警告。我参考了很多链接，但我仍然无法解决它。
