离子背景地理定位停止工作

Question

点击这段代码，我可以获得gps数据和检索地址都可以在后台很好地工作，在大约20分钟后，应用程序停止做我的方面。我尝试了电池优惠和其他可能的事情，我尝试了后台服务。但在漫长的时间过后，似乎没有任何东西可以在后台获得位置。任何建议。

this.backgroundGeolocation.configure(config).then(() => {


console.log('backgroundGeolocation configconfigconfigconfigconfigconfig');

this.backgroundGeolocation.on(BackgroundGeolocationEvents.location).subscribe((location: BackgroundGeolocationResponse) => {

    console.log(location);  
    this.ngZone.run(() => {


        this.geolocationService.nativeGeocoder.reverseGeocode(location.latitude, 
        location.longitude).then((result: NativeGeocoderResult[]) =>{

      console.log("JSON.stringify(result[0]",JSON.stringify(result[0]));
            this.comunenoreplace = result[0]['locality'];
            this.comune = result[0]['locality'].replace(/[^A-Z0-9]+/ig, "-");
            this.provincia = result[0]['subAdministrativeArea'].replace(new RegExp('Città Metropolitana di|Provincia di', 'g'), '');
            this.globalLatitude = location.latitude;
            this.globalLongitude = location.longitude;


          }).catch((error: any) => console.log("reverseGeocode", error));


    });
    // IMPORTANT:  You must execute the finish method here to inform the native plugin that you're finished,
    // and the background-task may be completed.  You must do this regardless if your operations are successful or not.
    // IF YOU DON'T, ios will CRASH YOUR APP for spending too much time in the background.
   // this.backgroundGeolocation.finish;
  });
});

您可以使用https://ionicframework.com/docs/native/background-mode

它只需修改应用程序的睡眠模式，使其在后台工作(而不会终止进程)。

如果进程被终止，那么应用程序可能会停止发送数据。

然后你可以让"cordova.plugins.backgroundMode.excludeFromTaskList()"；让它从任务列表中消失(Android 5.0+)

希望这能对您有所帮助:)
