Proguard阻止WebView中的Javascript工作

Question

我有一个类JSBridge (一个内部类)，它是一个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);
    }

这是很好的工作，直到我做了一个发行版与保护程序构建。我尝试跟随其他一些这样的答案，并将以下行添加到我的pro卫士文件中，但这并没有帮助。结果是我得到回调的调试版本，没有回调的发布版本。

-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接口方法使用@JavascriptInterface进行注释，则可以使用

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