ensureReady never returns

[CMahesh]

Hi,
I am starting the emulator and the using the ensureReady waiting for the promise to return on emulator completing the start. But, it is not returned only.
module.exports=(function(){

var androidhelper={};

androidhelper.startEmulator = function startEmulator(avdName){
return androidctrl.start(avdName)
.then(function(){
console.log("started")
return androidctrl.waitForDevice(avdName)
});
}
}
var m = require('./index2')
m.startEmulator('Nexus_4_API_21_1')
.then(function (result) {
console.log("started")
console.log(result);

}).caught(function(err){
console.log(err)

}).error(function(err){
console.log(err)
})
