Your Environment

Cordova:

cordova (Cordova CLI) : 8.1.1 (cordova-lib@8.1.0) Cordova Platforms : ios 4.5.5 Cordova Plugins : cordova-plugin-ionic-keyboard 2.1.3, cordova-plugin-ionic-webview 2.1.4, (and 12 other plugins)

System:

Android SDK Tools : 26.1.1 (/Users/mike/Library/Android/sdk) ios-deploy : 2.0.0 NodeJS : v10.11.0 (/Users/mike/.nvm/versions/node/v10.11.0/bin/node) npm : 6.4.1 OS : macOS Xcode : Xcode 10.0 Build version 10A255

## Expected Behavior
Like on my other iOS devices (iPhone SE, 6, 7) the app should stay alive in background mode to track the route and not restart. I use the aggressive tracking to print the user's exact walks on a map in foreground and background mode.

## Actual Behavior
After a short while, after opening the app which was in background mode (iPhone was locked), the app starts from scratch and the location tracking ended.

## Context
Downgrading to Uiwebview works better but the app restarts after a while again (after ~3km tracking). Downside: With Uiwebview the app is a way less efficient and needs much more memory.

iOS doesn't keep apps alive in the background. You can assume that after some time idle in the background, the OS will terminate your app to free up memory for other apps.

Also, don't use cordova-plugin-ionic-webview. That plugin is known to white-screen your app when OS boots it in the background.

Mike1707 commented 5 years ago

Hey Chris, thanks for your reply.

Do you have any ideas why the app is working for hours in background on e.g. iPhone 7 and just a few seconds on iPhone X? That seems kind of extreme for me. Also, there are in the logs some lines which look weired:

2018-10-02 10:43:41.707608+0200 MyAppTestDev[461:18010] ERROR Internal navigation rejected - <allow-navigation> not set for url='about:blank'

Could that be an indicator why the background time is so extremely different on my devices? Is there any chance to make it working for at least one hour in background mode?

Thanks in advance Mike

Edit: Do you have a recommendation for an alternative for cordova-plugin-ionic-webview? Just the Uiwebview (seems to be so old and outdated for me - Apple announced WkWebView for iOS 8 if I remember it right)?

christocracy commented 5 years ago

webview plugin. The developers of that plugin completely fail to take account of the case where apps might stay alive or get re-launched in the background.

Also, there are in the logs some lines which look weired:

No idea.

My primary iOS development device is an iPhone X. I had these issues before I removed the webview plugin.

Do you have a recommendation for an alternative for cordova-plugin-ionic-webview

No. Just get rid of it.

There's a dedicated tag "webview" in the issues, specifically for this.

Mike1707 commented 5 years ago

Okay, I will give it a try. Is there any other known plugin which can bring up problems? My actual plugin list looks as follows:

cordova-background-geolocation-lt 2.13.2 "BackgroundGeolocation"
cordova-plugin-app-version 0.1.9 "AppVersion"
cordova-plugin-background-fetch 5.4.1 "CDVBackgroundFetch"
cordova-plugin-camera 4.0.3 "Camera"
cordova-plugin-cocoalumberjack 0.0.4 "CocoaLumberjack"
cordova-plugin-device 2.0.2 "Device"
cordova-plugin-dialogs 2.0.1 "Notification"
cordova-plugin-google-analytics 1.8.6 "Google Universal Analytics Plugin"
cordova-plugin-ionic-keyboard 2.1.3 "cordova-plugin-ionic-keyboard"
cordova-plugin-ionic-webview 2.1.4 "cordova-plugin-ionic-webview"
cordova-plugin-splashscreen 5.0.2 "Splashscreen"
cordova-plugin-statusbar 2.4.2 "StatusBar"
cordova-plugin-whitelist 1.3.3 "Whitelist"
Mike1707 commented 5 years ago

Hi @christocracy

Today I found an entry on the github page of the cordova-plugin-ionic-webview for background mode. It seems they added some new functionality. Do you think this might be a solution for the issues with background tracking?

Compare: https://github.com/ionic-team/cordova-plugin-ionic-webview#wksuspendinbackground

christocracy commented 5 years ago

That option seems to have been added recently. Try it out and let me know.

Mike1707 commented 5 years ago

I have also an update for my initial issue. After upgrading to iOS 12.0.1, the background tracking seems to work again on iPhone XS. My tests worked all for hours in background mode. With 12.0.0 just for a few seconds.

christocracy commented 5 years ago

When you upgrade iOS, always restart the device after install complete.

Mike1707 commented 5 years ago

That option seems to have been added recently. Try it out and let me know.

I tried the new webview but I had other general issues. After the app suspended (without tracking), my app was not able to reach my backend anymore after waking up again. I never noticed something like that and therefore, I'll not use the webview for now!

christocracy commented 5 years ago

@Mike1707 Are you providing the plugin an #url and letting it handle uploading locations to your server?

dylanvdmerwe commented 5 years ago

The cordova-plugin-ionic-webview plugin is quite important for ionic applications (for both android and iOS apps) as it fixes many issues like scrolling. I would suggest against removing it. Please do log an issue with them so they can get it sorted rather.

Mike1707 commented 5 years ago

@Mike1707 Are you providing the plugin an #url and letting it handle uploading locations to your server?

No, I'm doing this on my own. But none of my requests worked in this case.

@dylanvdmerwe I'm going to log an issue but I need time to debug it first on my own.

christocracy commented 5 years ago

@Mike1707 Why are you posting locations "on your own"? They plugin's native HTTP service is superior at this task.

Mike1707 commented 5 years ago

Maybe I should refactor my code but until now I'm building a GeoJSON LineString Object locally and after finishing the tracking, I send this Object to my backend/database.

The purpose was to minimize the amount of backend requests.

Do you think this is bad practise?

christocracy commented 5 years ago

It seems ionic-webview have solved their issue booting in background as of version 2.0.3 (latest is 2.2.5)

Mike1707 commented 5 years ago

That are great news. Nevertheless, I have other big issues with webview and opened an issue as @dylanvdmerwe proposed (see https://github.com/ionic-team/cordova-plugin-ionic-webview/issues/215)

christocracy commented 5 years ago

Oh, lovely. I have an iPhone 6s still running iOS 11. I’ll compare that with iPhone X @ 12

obkdev commented 5 years ago

What is interesting... I was experiencing the same white screen on resume issue. I've now removed the webview plugin but my app goes white right after the splashscreen.

christocracy commented 5 years ago

Observe your JS web console for errors. Execute >window.location.reload() to observe your app booting.

obkdev commented 5 years ago

Xcode logs are giving me:

2019-03-22 16:48:00.366996+0000 LogIt-In[916:72045] Resetting plugins due to page load. 2019-03-22 16:48:00.491534+0000 LogIt-In[916:72101] NSURLConnection finished with error - code -1100

obkdev commented 5 years ago

If I've reinstalled webview 4.0.0 and now my app loads up again... Should I worry about the white screen on resume later?

christocracy commented 5 years ago

Should I worry about the white screen on resume later?

I don't know. I don't use Webview.

obkdev commented 5 years ago

I will report back when I know the answer for the next people who have the problem :)
