ionic + cordova-plugin-background-mode Unable to resume activity / Service not registered

[ishanthilina]

Following is the code I use to enable the background mode in my ionic app.

$ionicPlatform.ready(function() {

  cordova.plugins.backgroundMode.setDefaults({ text:'Doing heavy tasks.'});

    cordova.plugins.backgroundMode.enable();
    
    // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
    // for form inputs)
    if (window.cordova && window.cordova.plugins && window.cordova.plugins.Keyboard) {
      cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
      cordova.plugins.Keyboard.disableScroll(true);
    }
    if (window.StatusBar) {
      // org.apache.cordova.statusbar required
      StatusBar.styleDefault();
    }

    
    });

When I lock the screen when the app has focus (app is running in foreground) and try to unlock the screen again, I get the following exception.

But if I switch to another app and then lock screen, this does not happen.

What am I doing wrong?

@ishanthilina What plugin version do you use? Did you try out the latest master branch?

[jeroenverfallie]

@katzer We are receiving crash reports with the same error message, using the latest version of the plugin.

I can't reproduce the case from @ishanthilina. But the Firebase Crashlytics are presenting a considerable number of cases with this error, using the latest master branch.

The error occur on multiple android versions, but more than 50% with Android 8.

@katzer can you provide some help on this, something that we can use to try solve that error.

[Tioecomp]

Having the same problem android 8.0 and 9.0 did you have any sucess @lkonzen-garupa ?

[mirko77]

How was this fixed?

[mirko77]

Same issue on a couple of Android 9 devices. It does not happen always, it is random. Like once in three times...

[mirko77]

@lkonzen-garupa, @Tioecomp did you solve the issue?

[lkonzen-garupa]

@mirko77 yes, it was solved by stop using this plugin.
Instead we start using this one, seen to be maintened.

[mirko77]

@lkonzen-garupa thank you, I will give it a try.

[mirko77]

@lkonzen-garupa same issue with that plugin.
