如何配置ProGuard的对JavaScript界面​​？ [英] How to configure proguard for javascript interface?

问题描述

我有一个实现了一个web视图这需要使用JavascriptInterface的。它的正常工作时，不进行模糊处理，但一旦Proguard的是积极的，这是行不通的。我在这里看了看其他的答案，但我仍然无法得到它的工作。

I have a implemented a Webview which takes use of JavascriptInterface. It's working fine when not obfuscating, but at once Proguard is active, it does not work. I've looked here at other answers, but i still can't get it working.

部分的WebView类的：

public class Activity_Webview {
private WebView webView;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        webView = (WebView) findViewById(R.id.webview);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.addJavascriptInterface(new JavaScriptInterface (), "HTMLOUT");
        webView.setWebViewClient(mWebViewClient);
    }

    public class JavaScriptInterface implements NonObfuscateable{
        @JavascriptInterface
        public void processHTML(String html) {
        handleFinishFromWebView(html);
    }
}

我已经试过在Proguard的

-keep public class * implements com.project.NonObfuscateable
-keepclassmembers class * implements NonObfuscateable {
    public void processHTML(java.lang.String);
}

我也试过这个（当不执行NonObfuscateable接口

-keep public class com.project.Activity_Webview.JavaScriptInterface
-keep public class * implements com.project.Activity_Webview.JavaScriptInterface
-keepclassmembers class * implements com.project.Activity_Webview.JavaScriptInterface {
    <fields>;
    <methods>;
}

没有任何人有什么可能是错误的想法？ 在此先感谢

Does anybody have an idea of what could be wrong? Thanks in advance

推荐答案

无论你的配置可以工作，如果他们不包含错别字：

Both your configurations could have worked if they hadn't contained typos:

• ProGuard的要求完全合格的名称：

• ProGuard requires fully qualified names:

NonObfuscateable - > com.project.NonObfuscateable

编译的类使用$作为分隔符的内部类：

Compiled classes use '$' as a separator for inner classes:

com.project.Activity_Webview.JavaScriptInterface - > com.project.Activity_Webview $ JavaScriptInterface

在控制台日志，ProGuard的打印出对这种可疑的错别字说明。

In the console log, ProGuard prints out notes about such suspected typos.

保持注释Javascript的接口方法的一个更普遍的解决方案：

A more general solution for keeping annotated Javascript interface methods:

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