Proguard的無法工作

Question

停止使用Javascript在網頁視圖我有一個類JSBridge（一個內部類），這是一個JavaScript接口：

private class JsBridge implements JsCallback { 

    /** 
    * @param handlerName method required 
    * @param jsonData data passed through from javascript 
    * @param jsCallback A callback to trigger when handler specified by handlername has finished, could be null 
    */ 
    @JavascriptInterface 
    public void callHandler(final String handlerName, final String jsonData, final String jsCallback) { 
     Log.d(App.TAG, "Bridge call from JS, received " + handlerName); 
    } 

    @JavascriptInterface 
    public void onPageLoad(final String pageName) { 
     Log.d(App.TAG, "Bridge call from JS, received onPageLoad - we have the page name " + pageName); 
    } 

，直到我做一個發佈版本使用ProGuard這工作得很好。我試過下面的一些其他的答案，並添加了以下幾行到我的proguard文件，但它沒有幫助。結果是我得到回調的調試版本，發佈版本我沒有回調。

-keep public class * implements com.mixcloud.player.view.JsCallback 

-keepclassmembers class * implements com.mixcloud.player.view.JsCallback { 
    <methods>; 
} 
-keep public class * implements com.mixcloud.player.view.JsCallback 

-keepattributes *Annotation* 
-keepattributes JavascriptInterface 
-keep public class com.mixcloud.player.view.JSRefreshWebView 
-keep public class com.mixcloud.player.view.JSRefreshWebView$JsBridge 
-keep public class * implements com.mixcloud.player.view.JSRefreshWebView$JsBridge 
-keepclassmembers class * implements com.mixcloud.player.view.JSRefreshWebView$JsBridge { 
    <methods>; 
}

如果您的JavaScript接口方法與@JavascriptInterface註釋，你可以用

-keepclassmembers class * { 
    @android.webkit.JavascriptInterface <methods>; 
}
