Disable hardware acceleration Cordova Visual Studio

Question

I´m having perfomance problems on an Android application built in Cordova with Visual Studio 2013.

I read this questions:

Phonegap - cordova is laggy and slow on android and iOS devices

How do I set a background image on the WebView on Cordova/PhoneGap for Android?

Slow page transitions on Android with hardware acceleration on

and they talk about a file "src/com/.../MyApp.java" for disable hardware acceleration with this line:

super.appView.setLayerType(WebView.LAYER_TYPE_SOFTWARE, null);

My question is: Where is this file? I´m using Visual Studio 2013, and I can't find it.

Thanks!! Sorry for my english.
