How to configure proguard for javascript interface?

Question

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 looke

Answer 1

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

• ProGuard requires fully qualified names:

  NonObfuscateable -> com.project.NonObfuscateable

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

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

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

A more general solution for keeping annotated Javascript interface methods:

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