Context.startForegroundService() did not then call Service.startForeground() on Android 8.1

[FranciZ]

Your Environment

• Plugin version:1.8.0
• Platform: Android
• OS version: 8.1.0
• Device manufacturer / model: Pixel XL 2
• Nativescript version (tns info): 4.1.2
• Plugin config

{
            debug: false,
            desiredAccuracy: BackgroundGeolocation.DESIRED_ACCURACY_HIGH,
            stationaryRadius: 10,
            distanceFilter: 5,
            activityRecognitionInterval: 5000,
            notificationText: 'Loco service activated',
            notificationIcon: 'drawable/ic_notification'
}

Expected Behavior

App shouldn't crash.

Actual Behavior

App crashes throwing Context.startForegroundService() did not then call Service.startForeground() error.

This library is the only background service I'm using in the app so I'm assuming there's an issue here.

Steps to Reproduce

It's random, it happens every once in a while when putting the app to background and back to foreground.

Context

Nothing particular.

Do you have your license key configured?

[FranciZ]

I do, other than this error it works with the release apk.

[christocracy]

Show me your code you’re using to control the plugin.

[FranciZ]

Below is the code I use to start the plugin.

if (platform.isAndroid) {
permissions.requestPermission([
          android.Manifest.permission.ACCESS_FINE_LOCATION,
          android.Manifest.permission.ACCESS_COARSE_LOCATION],
        "We really need your location since it's a location based game ;)")
        .then(() => {

          // // 1. Listen to events
          BackgroundGeolocation.on('location', this.onLocation.bind(this));
          BackgroundGeolocation.on('motionchange', this.onMotionChange.bind(this));
          BackgroundGeolocation.on('http', this.onHttp.bind(this));
          BackgroundGeolocation.on('heartbeat', this.onHeartbeat.bind(this));
          BackgroundGeolocation.on('error', this.onError.bind(this));

          // 2. Configure it.
          BackgroundGeolocation.configure({
            debug: false,
            desiredAccuracy: BackgroundGeolocation.DESIRED_ACCURACY_HIGH,
            stationaryRadius: 25,
            distanceFilter: 50,
            activityRecognitionInterval: 10000,
            notificationText: 'Loco service activated',
            notificationIcon: 'drawable/ic_notification',
            url: `${config.API_HOST}/v1/game/${this.rootStore.game._id}/player/${this.rootStore.game.gamePlayerId}/location`
          }, (state) => {

            // 3. Plugin is now ready to use.
            if (!state.enabled) {
              console.log('LOCATION STARTING');
              BackgroundGeolocation.start();
            }
          });
        });
}

[christocracy]

You don’t need to worry about location permissions. The plugin handles that by itself.

This error can occur if you call #start and immediately #stop.

[FranciZ]

Thanks for the fast response. I did have that case in a while ago so that could be the reason for this error, have refactored a bit since to remove this. I still can't get the beta3 to work in release builds on 8.1 as mentioned in this issue, #117 .

[christocracy]

Show $ adb logcat of your app booting in release build.

[christocracy]

I don’t need hours of logs.

I just want a snapshot of your app booting from scratch. Shouldn’t be more than 15 seconds of logs.

[FranciZ]

:) Just ran adb logcat and this is what I got. Will reduce!

[christocracy]

Logcat is a live stream of the logs.

• Just start the stream.
• Boot your app
• when app crashes, [ctrl][c].

I deleted your previous message.

[FranciZ]

It's what I just did in the last comment which you removed. I cleared all the history, started the logcat, started the app, pressed [ctrl][c] after launching the app and pasted here. App does not crash. The background service seems to never start. No notification is present for the service and the location is not working in the app.

[christocracy]

If it doesn’t crash, show filtered plugin-only logs of your app booting.

$ adb logcat -s TSLocationManager

[FranciZ]

It's empty with 1.9.0beta4. Reverting to the 1.8.0 version it prints:
