webView console Uncaught TypeError
android 4.2系统上，混淆后，webView 不能正常调用JS
LOG提示：
Web Console(28886):Uncaught TypeError: Object [object Object] has no Method
混淆后，找不到方法，我试试了很多都不行，最后加了两句，解决了，
-keepattributes *Annotation*
-keepclassmembers class * {
@android.webkit.JavascriptInterface
}
下面的是RPOGUARD官网的android Application混淆的模板，
-injars bin/classes
-injars libs
-outjars bin/classes-processed.jar
-libraryjars/usr/local/java/android-sdk/platforms/android-9/android.jar
-dontpreverify
-repackageclasses ''
-allowaccessmodification
-optimizations!code/simplification/arithmetic
-keepattributes *Annotation*
-keep public class * extendsandroid.app.Activity
-keep public class * extendsandroid.app.Application
-keep public class * extendsandroid.app.Service
-keep public class * extendsandroid.content.BroadcastReceiver
-keep public class * extendsandroid.content.ContentProvider
-keep public class * extendsandroid.view.View {

public
public
public void set*(...);
}
-keepclasseswithmembers class * {
public
}
-keepclasseswithmembers class * {

}
-keepclassmembers class * extendsandroid.content.Context {
public void *(android.view.View);
public void *(android.view.MenuItem);
}
-keepclassmembers class * implementsandroid.os.Parcelable {
static ** CREATOR;
}
-keepclassmembers class **.R$* {

}
-keepclassmembers class * {

}
这里的是我的APP参考模板
