 ##### Methods
 
+- __getBundleUrl()__ - Returns the path to the most recent version of your app's JS bundle file, assuming that the resource name is `index.android.bundle`. If your app is using a different bundle name, then use the overloaded version of this method which allows specifying it. This method has the same resolution behavior as the Objective-C equivalent described above.

 - __getBundleUrl(String bundleName)__ - Returns the path to the most recent version of your app's JS bundle file, using the specified resource name (e.g. `index.android.bundle`). This method has the same resolution behavior as the Objective-C equivalent described above.
 
 - __getReactPackage()__ - Returns a `ReactPackage` object that should be added to your `ReactInstanceManager` via its `addPackage` method. Without this, the `react-native-code-push` JS module won't be available to your script.
