【问题描述】：

我正在尝试将 Proguard 添加到我的 ionic cordova 项目中。除了相机cordova 插件的take_picture 方法外，一切都运行良好。 proguard 规则主要是通过试错法添加的，所以可能会出现我看不到的错误，所以如果有处理 proguard 经验的人可以提供帮助，那就太好了。

这是我的proguard规则-

-keep class com.android.vending.licensing.ILicensingService


-keepattributes *Annotation*

-keepclassmembers enum * 
    public static **[] values();
    public static ** valueOf(java.lang.String);





-renamesourcefileattribute SourceFile    
-keepattributes SourceFile,LineNumberTable

# Enable proguard with Cordova
-keep class org.apache.**  *; 
-keep public class * extends org.apache.cordova.CordovaPlugin


-keep class com.google.android.gms.dynamite.DynamiteModule$DynamiteLoaderClassLoader  java.lang.ClassLoader sClassLoader; 
-keep class com.google.android.gms.dynamite.descriptors.com.google.android.gms.flags.ModuleDescriptor  int MODULE_VERSION; 
-keep class com.google.android.gms.dynamite.descriptors.com.google.android.gms.flags.ModuleDescriptor  java.lang.String MODULE_ID; 

-keep class org.apache.cordova.CordovaBridge  org.apache.cordova.PluginManager pluginManager; 
-keep class org.apache.cordova.CordovaInterfaceImpl  org.apache.cordova.PluginManager pluginManager; 
-keep class org.apache.cordova.CordovaResourceApi  org.apache.cordova.PluginManager pluginManager; 
-keep class org.apache.cordova.CordovaWebViewImpl  org.apache.cordova.PluginManager pluginManager; 
-keep class org.apache.cordova.ResumeCallback  org.apache.cordova.PluginManager pluginManager; 
-keep class org.apache.cordova.engine.SystemWebViewEngine  org.apache.cordova.PluginManager pluginManager; 

-keep class com.google.gson.internal.UnsafeAllocator  ** theUnsafe; 
-keep class me.leolin.shortcutbadger.ShortcutBadger  ** extraNotification; 
-keep class me.leolin.shortcutbadger.impl.XiaomiHomeBadger  ** messageCount; 
-keep class me.leolin.shortcutbadger.impl.XiaomiHomeBadger  ** extraNotification; 

-dontnote org.apache.harmony.xnet.provider.jsse.NativeCrypto
-dontnote sun.misc.Unsafe

-keep class com.worklight.androidgap.push.**  *; 
-keep class com.worklight.wlclient.push.**  *; 

# Enable proguard with Google libs
-keep class com.google.**  *; 
-dontwarn com.google.common.**
-dontwarn com.google.ads.**



-keep class net.sqlcipher.**  *; 
-dontwarn net.sqlcipher.**

-keep class org.codehaus.**  *; 
-keepattributes *Annotation*,EnclosingMethod

-keepclassmembers enum * 
    public static **[] values();
    public static ** valueOf(java.lang.String);


# Remove debug logs in release build
-assumenosideeffects class android.util.Log 
    public static *** d(...);


# These classes contain references to external jars which are not included in the default MobileFirst project.
-dontwarn com.worklight.common.internal.WLTrusteerInternal*
-dontwarn com.worklight.jsonstore.**
-dontwarn org.codehaus.jackson.map.ext.*
-dontwarn com.worklight.androidgap.push.GCMIntentService
-dontwarn com.worklight.androidgap.plugin.WLInitializationPlugin

-keep class  android.**
-dontwarn android.net.SSLCertificateSocketFactory
-dontwarn android.net.http.*
-keepclasseswithmembernames class android.support.v4.content
-dontwarn org.apache.**

#-keep class org.**  *; 

任何帮助都会很棒，等待肯定的答复。

【参考方案1】：

如果有人仍然卡在这个问题上

将此行添加到您的 proguard 规则中

-keep class com.abc.xyz.BuildConfig  *; 

com.abc.xyz 是你的包名

就是这样......

稍后谢谢我...
