javascript - Why is ionicPlatform.ready works randomly? -

i building ionic app , having problems "ionicplatform.ready" method.

i have declared in app.js, @ top :

.run(function($ionicplatform,config) {   $ionicplatform.ready(function() {     if(window.cordova && window.cordova.plugins.keyboard) {       // hide accessory bar default (remove show accessory bar above keyboard       // form inputs)       // don't remove line unless know doing. stops viewport       // snapping when text inputs focused. ionic handles internally       // nicer keyboard experience.       cordova.plugins.keyboard.hidekeyboardaccessorybar(true);       cordova.plugins.keyboard.disablescroll(true);       }     if(window.statusbar) {       statusbar.styledefault();     }      firebase.initializeapp({       apikey: config.firebase_api,       authdomain: config.firebase_auth_domain,       databaseurl: config.firebase_db_url,       storagebucket: config.firebase_storage,       messagingsenderid: config.firebase_storage     });     }); }) 

now, try log user in (used works super fine until morning decided not work anymore) :

.controller('logincontroller',['$scope',  '$ionicloading', '$timeout', '$firebasearray', 'config',  '$document', '$state', function($scope,  $ionicloading, $timeout, $firebasearray, config, $document, $state) {     // perform login action when user submits login form   $scope.dologin = function(userlogin) {         if($document[0].getelementbyid("user_name").value != "" && $document[0].getelementbyid("user_pass").value != ""){           // setup loader            $ionicloading.show({             content: 'loading',             animation: 'fade-in',             showbackdrop: true,             maxwidth: 200,             showdelay: 0           });         firebase.auth().signinwithemailandpassword(userlogin.username, userlogin.password).then(function() {              var userid = firebase.auth().currentuser.uid;           firebase.database().ref('accounts/' + userid + '/currentbusiness/').update({             name: "no current business arround",             description: "seems there's nothing arround...",              })                        $state.go("tab.account");          }, function(error) {           // error happened.           var errorcode = error.code;           var errormessage = error.message;            if (errorcode === 'auth/invalid-email') {              alert('enter valid email.');              $timeout(function () {                 $ionicloading.hide();              }, 1000);              return false;            }else if (errorcode === 'auth/wrong-password') {              alert('incorrect password.');              $timeout(function () {                 $ionicloading.hide();              }, 1000);              return false;            }else if (errorcode === 'auth/argument-error') {              alert('password must string.');              $timeout(function () {                 $ionicloading.hide();              }, 1000);              return false;            }else if (errorcode === 'auth/user-not-found') {              alert('no such user found.');              $timeout(function () {                 $ionicloading.hide();              }, 1000);              return false;            }else if (errorcode === 'auth/too-many-requests') {              alert('too many failed login attempts, please try after sometime.');              $timeout(function () {                 $ionicloading.hide();              }, 1000);              return false;            }else if (errorcode === 'auth/network-request-failed') {              alert('request timed out, please try again.');              $timeout(function () {                 $ionicloading.hide();              }, 1000);              return false;            }else {              alert(errormessage);              $timeout(function () {                 $ionicloading.hide();              }, 1000);              return false;            }         });     }else{         alert('please enter email , password');         return false;     }//end check client username password   };// end $scope.dologin()    // create callback logs current auth state    firebase.auth().onauthstatechanged(function(user) {     if (user) {       $state.go("tab.account");       // user signed in.     } else {       // no user signed in.     }   });   }]) 

now, doesn't work on devices (works on browser) unless call in controller :

var isandroid = ionic.platform.isandroid();       if(isandroid) {         firebase.initializeapp({         apikey: config.firebase_api,         authdomain: config.firebase_auth_domain,         databaseurl: config.firebase_db_url,         storagebucket: config.firebase_storage,         messagingsenderid: config.firebase_storage       });     } 

also, if later sign out of app, doesn't want come on login page because says there 2 times initialization of app (once in run , once in controller).

what missing ?
