i had 2 functions in code, invoke automatically. both used sync data server. 

$interval(function() {         var isonline = $cordovanetwork.isonline();         if (isonline) {             $scope.syncdata();         }     }, 900000)

and 

$rootscope.$on('$cordovanetwork:online', function(event, networkstate) {         if ($scope.isloggedin) {             var onlinestate = networkstate;             console.log('online state', onlinestate);             $scope.syncdata();         }      });

will functions call in background ? functions persist after app close ? couldn't find unusual during debug. can me ?

update

i found 2 scenarios occurred:

  1. i changing network state flight mode due network issue. got message unfortunately xxx has stopped
  2. my gps disabled. trying open google maps. got message google map enable gps. @ time enabled gps, got message unfortunately xxx has stopped

as mentioned in this question, caused bug in cordova.plugins.diagnostic@3.0.2, noted issue #85 in plugin repo , resolved patch release cordova.plugins.diagnostic@3.0.4. updating plugin , rebuilding app should resolve issue:

$ cordova plugin rm cordova.plugins.diagnostic &&    cordova plugin add cordova.plugins.diagnostic@3.0.4 &&   cordova build android --release
