Sencha Touch with Phonegap

I can't get a phonegap.local.properties, config.xml and packager.json. I'd like to use the phonegap camera API!!!!!!

When I use sencha cmd(version 5.0.2.270), there is no error,,,

[INF] Creating App[INF] Adding native build to app.json[INF] Application has been initialized for native packaging. Please edit app.json and add platform(s) to build for.

Oh, and I add {"platform": "android",} and "js": [ {"path": "cordova-2.2.0.js", "remote": true}....

Is it correct? How can I uses the phonegap api?

what should I do?

Here is a part i want to use phonegap API

Ext.define('TestCamera.view.Main', {

tabBarPosition: 'bottom',

items: [
