I have a problem that im searching for a solution since two days ago. After frustrating searchs, i will post here:

Im using last AndroidStudio version and im using a galaxy s4 mini for test.
When i debug it, everything works correct and a toast is showed.
The problem is when i generate a RELEASE application with command: ~/Server/gradle-1.8/bin/gradle assembleRelease
The application open, but when i touch the link that call my native function, it dont work and nothing happen. But with debug mode, it works.
Can anyone help me?
An image to understand better:
If Gradle is configured to use ProGuard, the @JavascriptInterface
annotations need to be explicitly preserved.
-keep public class com.mypackage.MyClass$MyJavaScriptInterface

-keepclassmembers class com.mypackage.MyClass$MyJavaScriptInterface {
<methods>;
}
-keepattributes JavascriptInterface
