Background Geolocation does not work under iOS #444

Closed HamzaLJ closed 6 years ago

HamzaLJ commented 6 years ago

I am using Ionic framework to develop my app, I've followed the documentation, everything works fine on Android; however on iOS it shows the blue bar that says that the app is tracking the current location on the background (only for the first 40 seconds), then that blue bar disappears and the app stop tracking the current location.

Your Environment

Expected Behavior

It should track the user current location in iOS even if the app goes to the background.

Actual Behavior

When going to the background, it shows the blue bar that says that the app is taking the current location on the background (only for the first 40 seconds), then that blue bar disappears and stop tracking the current location.

On the other hand, I have the same code working perfectly on Android devices, so I guess that there is an issue with the iOS.

Steps to Reproduce

Just follow the documentation on the following link : https://ionicframework.com/docs/native/background-geolocation/

Then run the app under iOS

Context

Track drivers location and update the database of the current driver location each 10 seconds.

This is not the Mauron85 version. Mauron85 is a fork from over 3 years ago of my original open source project.

HamzaLJ commented 6 years ago

So I need now to install the latest using cordova plugin add cordova-background-geolocation-lt ? Even purchase the license to make it work ?

christocracy commented 6 years ago

iOS is free. Android requires purchase.

You can try Android free in DEBUG builds.

As you can see, responses to issues is quite rapid here.

You'll be lucky to get any response at all from Mauron85.

christocracy commented 6 years ago

I see you re-posted your issue over at Mauron85.

You'll get no help there. You're on your own.

"You get what you pay for"

HamzaLJ commented 6 years ago

Well, I can't afford paying 300$ as I am currently a student and I'll be using the plugin for my capstone project

christocracy commented 6 years ago

If it just for a project and you're not actually submitting to play-store, you can run the Android version in DEBUG builds.

iOS is free

HamzaLJ commented 6 years ago

I know, but I am required to submit it to the playStore and let people use it and also collect their feedback about it. Not sure, if there exists a special discount for students

HamzaLJ commented 6 years ago

I've installed the plugin in iOS after removing the mauron85 version and it didn't worked at all, here is the code : 

          this.platform.ready().then((ready) => {
          this.configureBackgroundGeolocation(this);
          });

            this.configureBackgroundGeolocation() {
            // 1. Get a reference to the plugin
            this.bgGeo = (<any>window).BackgroundGeolocation;

            // 2. Listen to events
            this.bgGeo.on('location', this.onLocation.bind(this));
            this.bgGeo.on('motionchange', this.onMotionChange.bind(this));

            // 3. Configure it.
            this.bgGeo.configure({
              debug: false,
              desiredAccuracy: 0,
              distanceFilter: 10,
              autoSync: true
            }, (state) => {
              // 4. Start the plugin.
              this.bgGeo.start();
            });
          }

          onLocation(location, taskId) {
             console.log('- location: ', location);
             this.bgGeo.finish(taskId);
           }
           onMotionChange(isMoving, location, taskId) {
             console.log('- motionchange: ', isMoving, location);
             this.bgGeo.finish(taskId);
           }

When I go to the background even that blue bar does not show up, am I doing something wrong?

christocracy commented 6 years ago

Logs.

HamzaLJ commented 6 years ago

When the app goes to the background I don't receive any logs, which means that possibly the plugin does not fire when being on the background

christocracy commented 6 years ago

Why would you use debug: false when something isn't working??

See logLevel

HamzaLJ commented 6 years ago

I'll change it now to debug: true and let you know what happens

christocracy commented 6 years ago

The blue bar isn't supposed to show.

HamzaLJ commented 6 years ago

changed it to debug: true didn't changed anything

christocracy commented 6 years ago

You'll get no logs without setting logLevel: bgGeo.LOG_LEVEL_VERBOSE

HamzaLJ commented 6 years ago

Where should I set it ?

christocracy commented 6 years ago

Did you read the docs for logLevel?

HamzaLJ commented 6 years ago

I've done the following:

  this.bgGeo.configure({
       debug: true,
       desiredAccuracy: 0,
       distanceFilter: 10,
       logLevel: this.bgGeo.LOG_LEVEL_VERBOSE,
       autoSync: true
     }, (state) => {
       // 4. Start the plugin.
       this.bgGeo.start();
     });`
HamzaLJ commented 6 years ago

Yes I did. Even after adding logLevel: this.bgGeo.LOG_LEVEL_VERBOSE I still don't get any logs

christocracy commented 6 years ago

Then the plugin is not installed.

As you can see, it's already installed...

HamzaLJ commented 6 years ago

Seems that this.configureBackgroundGeolocation(this); never fires

christocracy commented 6 years ago

That would be your problem.

HamzaLJ commented 6 years ago

Weird, I've placed the following this.configureBackgroundGeolocation(this); in the exact place where mauron85 was. In the case of mauron85 it was firing without problem, but now cordova-background-geolocation-lt does not fire up

HamzaLJ commented 6 years ago

I've done some changes to be like the following : this.platform.ready().then(this.configureBackgroundGeolocation.bind(this));

It seems that it fired.

Here is what I got :

christocracy commented 6 years ago

The plugin is not installed properly. Cordova gets confused sometimes.

In your XCode project, you should see CDVBackgroundGeolocation in the /Plugins folder:

HamzaLJ commented 6 years ago

I didn't found CDVBackgroundGeolocation in the /Plugins folder

I'll re-install the plugin

christocracy commented 6 years ago

It's Cordova's responsibility to place those files into the XCode project. Sometimes it fails. You probably uninstalled Mauron85 version after installing mine. The two plugins have identically named ios files CDVBackgroundGeolocation.m/.h, since Mauron85 version is a fork of this project.

HamzaLJ commented 6 years ago

Now, it works fine only on foreground.

Background & Terminated are two completely different states. Are you terminating the app?

HamzaLJ commented 6 years ago

Not at all, only going to the background (for example opening Google maps, etc...)

HamzaLJ commented 6 years ago

Receiving the following :

🔴-[TSGeofenceManager stopMonitoringGeofences] 🔴-[SOMotionDetector stopDetection] OFF 🔴-[TSLocationManager stopUpdatingLocation] 2017-08-24 15:16:55.330214+0100 Onadi Driver[871:132422] THREAD WARNING: ['BackgroundGeolocation'] took '60.975586' ms.

Also, I am getting a notification "Stopped on terminate"

christocracy commented 6 years ago

Your app is being terminated, either by you or the OS. That's not the plugin's fault.

If you don't want tracking to cease when user or OS terminates your app, configure stopOnTerminate: false

HamzaLJ commented 6 years ago

I've solved it by accessing to the app settings and checked "Always" to enable background tracking even if the app is in the background. However, I am already setting a function that should trigger on an interval of 10 seconds but I receive a notification that says "Background fetch received" sometimes after 10 min or sometimes after 15min.. Any idea on what could be wrong?

christocracy commented 6 years ago

You do not need to use cordova-plugin-geolocation with this plugin. In fact, it's a bad idea, since cordova-plugin-geolocation requests When In Use permissions while this plugin requests Always.

Whichever plugin requests location first, that's the authorization request which will be show to the user.

This plugin has its own #getCurrentPosition method.

However, I am already setting a function that should trigger on an interval of 10 seconds

When an iOS app is in the background without locations-services on, your app is suspended. If you're hoping to do a setInterval with Javascript while your app is in the background and the device is stationary, that's not going to happen.

a notification that says "Background fetch received" sometimes after 10 min or sometimes after 15min..

This plugin requires my cordova-plugin-background-fetch plugin as a dependency. Read the docs for that plugin. This plugin is already included in your app and available to you at window.BackgroundFetch. Feel free to implement a callback as documented there. The plugin uses this plugin internally for its own purposes.

HamzaLJ commented 6 years ago

Good then, I guess that I need to remove cordova-plugin-geolocation but can I still get the current position when the user is on the foreground ?

However, for the cordova-plugin-background-fetch

It says that :

iOS Background Fetch is basically an API which wakes up your app about every 15 minutes

As of my understanding, it'll fetch each 15minutes, but I am willing to execute my function each 10 seconds. It's either my understanding is wrong or it's not possible to execute the function in background each 10 seconds when working with iOS

christocracy commented 6 years ago

but can I still get the current position when the user is on the foreground ?

Yes, as I said above: "this plugin has its own getCurrentPosition method"

but I am willing to execute my function each 10 seconds. It's either my understanding is wrong

Your understanding is wrong. As I said above: "When an iOS app is in the background without locations-services on, your app is suspended. If you're hoping to do a setInterval with Javascript while your app is in the background and the device is stationary, that's not going to happen."

christocracy commented 6 years ago

Read the plugin's Philosophy of Operation

HamzaLJ commented 6 years ago

Got it, basically. As of my understanding background fetch will happen only when the device is moving, getting a new user location and not in stationary. Please correct me if I am wrong.

christocracy commented 6 years ago

Background fetch has nothing to do with geolocation or whether the device is moving.

Please read the docs.
