#1

Dear Development Team,

I’m facing this problem from last 2 months while testing it on android device, and i think many developers like me is facing the same.
I request you to please resolve this and give us a solution.

Below is my code -

this.geofence.initialize().then(() =>{
            alert('Geofence Plugin Ready')
            this.addGeofence()
          },(err) => {
            alert(err)
          }) 

addGeofence(){
    let fence = [
      {
        id: 'enter',
        latitude: 28.6016271,
        longitude: 77.3519364,
        radius: 500,
        transitionType: 1,
        notification: {
          id: 1,
          title: 'You crossed a fence',
          text: 'You just arrived XYZ',
          openAppOnClick: true
        }
      },{
        id: 'exit',
        latitude: 28.6016271,
        longitude: 77.3519364,
        radius: 500,
        transitionType: 2,
        notification: {
          id: 2,
          title: 'You crossed a fence',
          text: 'You just left XYZ',
          openAppOnClick: true
        }
      }  ]
    this.geofence.addOrUpdate(fence).then(
      () => alert('Geofence added'),
     (err) => console.log('Geofence failed to add')
    )

    this.geofence.getWatched().then(
      (res) => console.log('Geofence Watching  ::' + res),
      (err) => console.log('Geofence Error is  :  ' + err)
    )

    this.geofence.onTransitionReceived().subscribe((resp) => {
      // this.number = this.number + 1;
     
      console.log("geofence on transition received");
    },(err) =>{
      alert('error'+err)
    })
  }

I am using ionic version 3.20.0
