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

<ul>
<li>ProGuard requires fully qualified names:

<code>NonObfuscateable</code> -> <code>com.project.NonObfuscateable</code></li>
<li>Compiled classes use '$' as a separator for inner classes:

<code>com.project.Activity_Webview.JavaScriptInterface</code> -> <code>com.project.Activity_Webview$JavaScriptInterface</code></li>
</ul>

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

A more general solution for keeping annotated Javascript interface methods:

<pre><code>-keepclassmembers class * {
 @android.webkit.JavascriptInterface &lt;methods&gt;;
}
</code></pre>

If you're using obfuscation, in addition to <a href="https://stackoverflow.com/a/17637530/9636">Eric Lafortune's answer</a> you also need:

<pre><code>-keepattributes JavascriptInterface
</code></pre>

In my case work only code:

-keep public class **.*$MyJavascriptInteface
-keep public class **.*$JavaScriptInterface

Java code:

<pre><code>@SuppressLint("SetJavaScriptEnabled")
public class ActivityWebView extends Activity {
 ...
 webView.getSettings().setJavaScriptEnabled(true);
 webView.addJavascriptInterface(new MyJavascriptInterface(MyActivity.this), "MyJSI");

 ....

 public class MyJavaScriptInterface {

 Context context;

 MyJavascriptInterface(Context context) {
 this.context = context;
 }

 @JavascriptInterface
 @SuppressWarnings("unused")
 public void myjavascriptfunction() {

 }
 ...
}
</code></pre>

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.

Some of the WebView class:

<pre><code>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);
 }
}
</code></pre>

What i've tried in Proguard:

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

I've also tried this (when not implementing NonObfuscateable interface:

<pre><code>-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 {
 &lt;fields&gt;;
 &lt;methods&gt;;
}
</code></pre>

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

How to configure proguard for javascript interface?

Java

我已经实现了一个Webview，它使用了JavascriptInterface。它在没有混淆的时候工作得很好，但是一旦Proguard被激活，它就不能工作了。我看了这里的其他答案，但我仍然不能让它工作。一些WebView类：public class Activity_Webview {private WebView w...
