我正在尝试在我的一个Ionic-3应用程序中使用地理围栏 . 按照https://ionicframework.com/docs/native/geofence/中的说明操作后，我修改了我的app.components.ts，现在看起来像这样：
import { Geofence } from '@ionic-native/geofence';
@Component({ templateUrl: 'app.html' }) export class MyApp {
constructor(private geofence: Geofence) {
platform.ready().then(() => {
// Okay, so the platform is ready and our plugins are available.
// Here you can do any higher level native things you might need.
statusBar.styleDefault();
splashScreen.hide();
this.startGeofence();
});
this.pages = [
]; }
startGeofence() {
// initialize the plugin
this.geofence.initialize().then(
// resolved promise does not return a value
() => {
console.log('Geofence Plugin Ready');
this.addGeofence();
},
(err) => {
console.log('Geofence Plugin failed');
console.log(err);
}
) }
private addGeofence() {
this.geofence.removeAll();
//options describing geofence
let fence = {
id: '69ca1b88-6fbe-4e80-a4d4-ff4d3748acab', //any unique ID
latitude: 41.2713354, //center of geofence radius
longitude: 18.6108311,
radius: 20, //radius to edge of geofence in meters
transitionType: 3, //see 'Transition Types' below
notification: { //notification settings
id: 3, //any unique ID
title: 'Geofencing', //notification title
text: 'my home', //notification body
openAppOnClick: true //open app when notification is tapped
}
}
this.geofence.addOrUpdate(fence).then(
() => console.log('Geofence added'),
(err) => console.log('Geofence failed to add')
);
this.geofence.onTransitionReceived().subscribe(resp => {
resp.forEach(function (geo) {
console.log("Geofence transition detected", geo);
});
console.log("geofence on transition recieved", resp);
alert(JSON.stringify(resp));
}); } }
在控制台日志中，我有以下消息：
deviceready在5秒后没有发射 . Ionic Native：4964 ms之后触发的deviceready事件Geofence Plugin Ready Geofence添加
那些显示插件的正确初始化，但是，之后没有任何反应，从不调用onTransitionReceived . 我使用的是Android 6.0智能手机 .
