I found a solution for some regular background activity!

Hi, Even I’m facing the same doubt ? any solution you found ?

No, I did not find a solution else

You are also facing issues on receiving notifications when app is killed in Android 8 and above ?

No, I believe that we don’t have the same problem, in my case I don’t receive any notification, I want simply that my application keep running even if the screen is sleeping. There is no error in my code but I want to apply the @boltex’s solution but it doesn’t work and I don’t know where I must put the code above

please, help me… where I should implement this code:

if( ionic.Platform.isAndroid() ){
cordova.plugins.backgroundMode.enable();

window.powerManagement.dim(function() {
  console.log('Wakelock acquired');
}, function() {
  console.log('Failed to acquire wakelock');
});
window.powerManagement.setReleaseOnPause(false, function() {
  console.log('setReleaseOnPause successfully');
}, function() {
  console.log('Failed to set');
});
}
  initializeApp() {
    this.platform.ready().then(() => {
      this.powerManagement.dim().then(
        res => console.log('Wakelock acquired'),
        () => {
          console.log('Failed to acquire wakelock');
        }
      );
      this.powerManagement.setReleaseOnPause(false).then(
        res => console.log('setReleaseOnPause successfully'),
        () => {
          console.log('Failed to set');
        }
      );
      this.statusBar.styleDefault();
      this.splashScreen.hide();
    });
  }

You can put it in app.component.ts ( I am using v4 )

I put code here, and edit. My screen didn’t close but background app still work like 5 mins. It is not a completely solution for Android v8.
