Menu
I use the sample provided by Google for demonstrating two way communication between JavaScript and Java ,
ref[1]:
http://code.google.com/p/apps-for-android/source/browse/trunk/Samples/WebViewDemo/src/com/google/android/webviewdemo/WebViewDemo.java
The functionality is working fine. I am able to call JavaScript function from Java and callback the Java function from JavaScript.
The problem is when I use an alert inside a JavaScript function it won`t appear, but the functionality inside the function is working properly.
Why does alert("test") inside a JavaScript function not appear in Android.
I load the JavaScript in a web-view. When I a clicking button in Android
I call the function, but it does not appear.
If anyone knows the problem, pealse help me out.
Thanks
