How to use proguard in cordova android App

Question

I have a finished cordova project and i want to use proguard inorder to prevent others from reverse engineering the APK.But i have trouble doing this.

In http://developer.android.com/tools/help/proguard.html

It says that "When you create an Android project, a proguard.cfg file is automatically generated in the root directory of the project. " But i cannot find a such file. So how do i apply proguard to my app?

Thank you

You need to uncomment below lines from your project.properties file

To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

Also, if you are using Webview with JS, uncomment following lines in proguard-project.txt and specify the fully qualified class name to the JavaScript interface class:

-keepclassmembers class com.your.package.YourJSInterfaceClass {
   public *;
}
