Checking first time app launch using Cordova 3.0

Is there a way in Cordova 3.0 to check if that's the first time the application runs without using the DB for that purpose.

You must use sessionStorage instead of localStorage.

The correct code will be:

var count = window.sessionStorage.getItem('hasRun');

if (count) {
  console.log("second time app launch");
} else {
  // set variable in localstore
  window.sessionStorage.setItem('hasRun', 1);
  console.log("first time app launch");
}

It's because localStorage is persistent while sessionStorage ain't..

You could use localStorage to check for a variable. Try something like this:

in docummentready event:

if(window.localStorage.getItem('has_run') == '') {
    //do some stuff if has not loaded before
    window.localStorage.setItem('has_run', 'true');
}

Dawson Loudon's solution didn't work for me but try this:

var count = window.localStorage.getItem('hasRun');

if(count){
   console.log("second time app launch");
}else{
  // set variable in localstore
  window.localStorage.setItem('hasRun',1);
  console.log("first time app launch");
}
